Machine ClassAd Attributes¶

AcceptedWhileDraining: Boolean which indicates if the slot accepted its current job while the machine was draining.

Activity

String which describes HTCondor job activity on the machine. Can have one of the following values:

"Idle": There is no job activity
"Busy": A job is busy running
"Suspended": A job is currently suspended
"Vacating": A job is currently checkpointing
"Killing": A job is currently being killed
"Benchmarking": The startd is running benchmarks
"Retiring": Waiting for a job to finish or for the maximum retirement time to expire

Arch

String with the architecture of the machine. Currently supported architectures have the following string definitions:

"INTEL": Intel x86 CPU (Pentium, Xeon, etc).
"X86_64": AMD/Intel 64-bit X86

CanHibernate: The condor_startd has the capability to shut down or hibernate a machine when certain configurable criteria are met. However, before the condor_startd can shut down a machine, the hardware itself must support hibernation, as must the operating system. When the condor_startd initializes, it checks for this support. If the machine has the ability to hibernate, then this boolean ClassAd attribute will be True. By default, it is False.

ClockDay: The day of the week, where 0 = Sunday, 1 = Monday, …, and 6 = Saturday.
ClockMin: The number of minutes passed since midnight.

CondorLoadAvg: The load average contributed by HTCondor, either from remote jobs or running benchmarks.

CondorVersion: A string containing the HTCondor version number for the condor_startd daemon, the release date, and the build identification number.

ConsoleIdle: The number of seconds since activity on the system console keyboard or console mouse has last been detected. The value can be modified with SLOTS_CONNECTED_TO_CONSOLE as defined in the condor_startd Configuration File Macros section.

Cpus: The number of CPUs (cores) in this slot. It is 1 for a single CPU slot, 2 for a dual CPU slot, etc. For a partitionable slot, it is the remaining number of CPUs in the partitionable slot.

CpuFamily: On Linux machines, the Cpu family, as defined in the /proc/cpuinfo file.
CpuModel: On Linux machines, the Cpu model number, as defined in the /proc/cpuinfo file.

CpuCacheSize: On Linux machines, the size of the L3 cache, in kbytes, as defined in the /proc/cpuinfo file.

CurrentRank: A float which represents this machine owner’s affinity for running the HTCondor job which it is currently hosting. If not currently hosting an HTCondor job, CurrentRank is 0.0. When a machine is claimed, the attribute’s value is computed by evaluating the machine’s Rank expression with respect to the current job’s ClassAd.
DetectedCpus: Set by the value of configuration variable DETECTED_CORES

DetectedMemory: Set by the value of configuration variable DETECTED_MEMORY. Specified in MiB.

Disk: The amount of disk space on this machine available for the job in KiB (for example, 23000 = 23 MiB). Specifically, this is the amount of disk space available in the directory specified in the HTCondor configuration files by the EXECUTE macro, minus any space reserved with the RESERVED_DISK macro. For static slots, this value will be the same as machine ClassAd attribute TotalSlotDisk. For partitionable slots, this value will be the quantity of disk space remaining in the partitionable slot.

Draining: This attribute is True when the slot is draining and undefined if not.

DrainingRequestId: This attribute contains a string that is the request id of the draining request that put this slot in a draining state. It is undefined if the slot is not draining.

DotNetVersions

The .NET framework versions currently installed on this computer. Default format is a comma delimited list. Current definitions:

"1.1"
for .Net Framework 1.1

"2.0"
for .Net Framework 2.0

"3.0"
for .Net Framework 3.0

"3.5"
for .Net Framework 3.5

"4.0Client"
for .Net Framework 4.0 Client install

"4.0Full"
for .Net Framework 4.0 Full install

DynamicSlot: For SMP machines that allow dynamic partitioning of a slot, this boolean value identifies that this dynamic slot may be partitioned.

EnteredCurrentActivity: Time at which the machine entered the current Activity (see Activity entry above). On all platforms (including NT), this is measured in the number of integer seconds since the Unix epoch (00:00:00 UTC, Jan 1, 1970).

ExpectedMachineGracefulDrainingBadput: The job run time in cpu-seconds that would be lost if graceful draining were initiated at the time this ClassAd was published. This calculation assumes that jobs will run for the full retirement time and then be evicted without saving a checkpoint.

ExpectedMachineGracefulDrainingCompletion: The estimated time at which graceful draining of the machine could complete if it were initiated at the time this ClassAd was published and there are no active claims. This is measured in the number of integer seconds since the Unix epoch (00:00:00 UTC, Jan 1, 1970). This value is computed with the assumption that the machine policy will not suspend jobs during draining while the machine is waiting for the job to use up its retirement time. If suspension happens, the upper bound on how long draining could take is unlimited. To avoid suspension during draining, the SUSPEND and CONTINUE expressions could be configured to pay attention to the Draining attribute.

ExpectedMachineGracefulQuickBadput: The job run time in cpu-seconds that would be lost if quick or fast draining were initiated at the time this ClassAd was published. This calculation assumes that all evicted jobs will not save a checkpoint.

ExpectedMachineQuickDrainingCompletion: Time at which quick or fast draining of the machine could complete if it were initiated at the time this ClassAd was published and there are no active claims. This is measured in the number of integer seconds since the Unix epoch (00:00:00 UTC, Jan 1, 1970).

FileSystemDomain: A domain name configured by the HTCondor administrator which describes a cluster of machines which all access the same, uniformly-mounted, networked file systems usually via NFS or AFS. This is useful for Vanilla universe jobs which require remote file access.
HasDocker: A boolean value set to True if the machine is capable of executing docker universe jobs.

HasEncryptExecuteDirectory: A boolean value set to True if the machine is capable of encrypting execute directories.

HasFileTransfer: A boolean value that when True identifies that the machine can use the file transfer mechanism.

HasFileTransferPluginMethods: A string of comma-separated file transfer protocols that the machine can support. The value can be modified with FILETRANSFER_PLUGINS as defined in condor_starter Configuration File Entries.

HasUserNamespaces: A boolean value that when True identifies that the jobs on this machine can create user namespaces without root privileges.

Has_sse4_1: A boolean value set to True if the machine being advertised supports the SSE 4.1 instructions, and Undefined otherwise.

Has_sse4_2: A boolean value set to True if the machine being advertised supports the SSE 4.2 instructions, and Undefined otherwise.

has_ssse3: A boolean value set to True if the machine being advertised supports the SSSE 3 instructions, and Undefined otherwise.

has_avx: A boolean value set to True if the machine being advertised supports the avx instructions, and Undefined otherwise.

has_avx2: A boolean value set to True if the machine being advertised supports the avx2 instructions, and Undefined otherwise.

has_avx512dnni: A boolean value set to True if the machine being advertised support the avx512dnni instructions.

HasSelfCheckpointTransfers: A boolean value set to True if the machine being advertised supports transferring (checkpoint) files (to the submit node) when the job successfully self-checkpoints.

HasSingularity: A boolean value set to True if the machine being advertised supports running jobs within Singularity containers.

HasVM: If the configuration triggers the detection of virtual machine software, a boolean value reporting the success thereof; otherwise undefined. May also become False if HTCondor determines that it can’t start a VM (even if the appropriate software is detected).

IsWakeAble: A boolean value that when True identifies that the machine has the capability to be woken into a fully powered and running state by receiving a Wake On LAN (WOL) packet. This ability is a function of the operating system, the network adapter in the machine (notably, wireless network adapters usually do not have this function), and BIOS settings. When the condor_startd initializes, it tries to detect if the operating system and network adapter both support waking from hibernation by receipt of a WOL packet. The default value is False.

IsWakeEnabled: If the hardware and software have the capacity to be woken into a fully powered and running state by receiving a Wake On LAN (WOL) packet, this feature can still be disabled via the BIOS or software. If BIOS or the operating system have disabled this feature, the condor_startd sets this boolean attribute to False.

JobBusyTimeAvg: The Average lifetime of all jobs, including transfer time. This is determined by measuring the lifetime of each condor_starter that has exited. This attribute will be undefined until the first time a condor_starter has exited.

JobBusyTimeCount: The total number of of jobs used to calulate the JobBusyTimeAvg attribute. This is also the the total number times a condor_starter has exited.

RecentJobBusyTimeAvg: The Average lifetime of all jobs that have exited in the last 20 minutes, including transfer time. This is determined by measuring the lifetime of each condor_starter that has exited in the last 20 minutes. This attribute will be undefined if no condor_starter has exited in the last 20 minutes.

RecentJobBusyTimeCount: The total number of jobs used to calulate the RecentJobBusyTimeAvg attribute. This is also the the total number times a condor_starter has exited in the last 20 minutes.

This is determined by measuring the lifetime of each condor_starter s that has exited in the last 20 minutes. This attribute will be undefined if no condor_starter has exited in the last 20 minutes.

RecentJobBusyTimeMin: The Minimum lifetime of all jobs, including transfer time. This is determined by measuring the lifetime of each condor_starter that has exited. This attribute will be undefined if no condor_starter has exited in the last 20 minutes.

JobDurationAvg: The Average lifetime time of all jobs, not including time spent transferring files. This attribute will be undefined until the first time a job exits. Jobs that never start (because they fail to transfer input, for instance) will not be included in the average.

JobDurationCount: The total number of of jobs used to calulate the JobDurationAvg attribute. This is also the the total number times a job has exited. Jobs that never start (because input transfer fails, for instance) are not included in the count.

JobDurationMax: The lifetime of the longest lived job that has exited. This attribute will be undefined until the first time a job exits.

JobDurationMin: The lifetime of the shortest lived job that has exited. This attribute will be undefined until the first time a job exits.

RecentJobDurationAvg: The Average lifetime time of all jobs, not including time spent transferring files, that have exited in the last 20 minutes. This attribute will be undefined if no job has exited in the last 20 minutes.

RecentJobDurationCount: The total number of jobs used to calulate the RecentJobDurationAvg attribute. This is the total number of jobs that began execution and have exited in the last 20 minutes.

RecentJobDurationMax: The lifetime of the longest lived job that has exited in the last 20 minutes. This attribute will be undefined if no job has exited in the last 20 minutes.

RecentJobDurationMin: The lifetime of the shortest lived job that has exited in the last 20 minutes. This attribute will be undefined if no job has exited in the last 20 minutes.

JobPreemptions: The total number of times a running job has been preempted on this machine.

JobStarts: The total number of jobs which have been started on this machine since the condor_startd started running.

JobUserPrioPreemptions: The total number of times a running job has been preempted on this machine based on a fair share allocation of the pool since the condor_startd started running.

JobVM_VCPUS: An attribute defined if a vm universe job is running on this slot. Defined by the number of virtualized CPUs in the virtual machine.

KeyboardIdle: The number of seconds since activity on any keyboard or mouse associated with this machine has last been detected. Unlike ConsoleIdle, KeyboardIdle also takes activity on pseudo-terminals into account. Pseudo-terminals have virtual keyboard activity from telnet and rlogin sessions. Note that KeyboardIdle will always be equal to or less than ConsoleIdle. The value can be modified with SLOTS_CONNECTED_TO_KEYBOARD as defined in the condor_startd Configuration File Macros section.

KFlops: Relative floating point performance as determined via a Linpack benchmark.

LastDrainStartTime: Time when draining of this condor_startd was last initiated (e.g. due to condor_defrag or condor_drain).

LastDrainStopTime: Time when draining of this condor_startd was last stopped (e.g. by being cancelled).

LastHeardFrom: Time when the HTCondor central manager last received a status update from this machine. Expressed as the number of integer seconds since the Unix epoch (00:00:00 UTC, Jan 1, 1970). Note: This attribute is only inserted by the central manager once it receives the ClassAd. It is not present in the condor_startd copy of the ClassAd. Therefore, you could not use this attribute in defining condor_startd expressions (and you would not want to).

LoadAvg: A floating point number representing the current load average.

Machine: A string with the machine’s fully qualified host name.

MachineMaxVacateTime: An integer expression that specifies the time in seconds the machine will allow the job to gracefully shut down.

MaxJobRetirementTime: When the condor_startd wants to kick the job off, a job which has run for less than this number of seconds will not be hard-killed. The condor_startd will wait for the job to finish or to exceed this amount of time, whichever comes sooner. If the job vacating policy grants the job X seconds of vacating time, a preempted job will be soft-killed X seconds before the end of its retirement time, so that hard-killing of the job will not happen until the end of the retirement time if the job does not finish shutting down before then. This is an expression evaluated in the context of the job ClassAd, so it may refer to job attributes as well as machine attributes.
Memory: The amount of RAM in MiB in this slot. For static slots, this value will be the same as in TotalSlotMemory. For a partitionable slot, this value will be the quantity remaining in the partitionable slot.
Mips: Relative integer performance as determined via a Dhrystone benchmark.

MonitorSelfResidentSetSize: The amount of resident memory used by this daemon in KiB.

MonitorSelfSecuritySessions: The number of open (cached) security sessions for this daemon.

MonitorSelfTime: The time, represented as the number of second elapsed since the Unix epoch (00:00:00 UTC, Jan 1, 1970), at which this daemon last checked and set the attributes with names that begin with the string MonitorSelf.

MyAddress: String with the IP and port address of the condor_startd daemon which is publishing this machine ClassAd. When using CCB, condor_shared_port, and/or an additional private network interface, that information will be included here as well.

MyType: The ClassAd type; always set to the literal string "Machine".

Name: The name of this resource; typically the same value as the Machine attribute, but could be customized by the site administrator. On SMP machines, the condor_startd will divide the CPUs up into separate slots, each with with a unique name. These names will be of the form “slot#@full.hostname”, for example, “slot1@vulture.cs.wisc.edu”, which signifies slot number 1 from vulture.cs.wisc.edu.

Offline<name>: A string that lists specific instances of a user-defined machine resource, identified by name. Each instance is currently unavailable for purposes of match making.

OfflineUniverses

A ClassAd list that specifies which job universes are presently offline, both as strings and as the corresponding job universe number. Could be used the the startd to refuse to start jobs in offline universes:

RetirementTimeRemaining: An integer number of seconds after MyCurrentTime when the running job can be evicted. MaxJobRetirementTime is the expression of how much retirement time the machine offers to new jobs, whereas RetirementTimeRemaining is the negotiated amount of time remaining for the current running job. This may be less than the amount offered by the machine’s MaxJobRetirementTime expression, because the job may ask for less.

SingularityVersion: A string containing the version of Singularity available, if the machine being advertised supports running jobs within a Singularity container (see HasSingularity).

SlotID

For SMP machines, the integer that identifies the slot. The value will be X for the slot with

name="slotX@full.hostname"

For non-SMP machines with one slot, the value will be 1.

SlotType: For SMP machines with partitionable slots, the partitionable slot will have this attribute set to "Partitionable", and all dynamic slots will have this attribute set to "Dynamic".

SlotWeight: This specifies the weight of the slot when calculating usage, computing fair shares, and enforcing group quotas. For example, claiming a slot with SlotWeight = 2 is equivalent to claiming two SlotWeight = 1 slots. See the description of SlotWeight in condor_startd Configuration File Macros.

StartdIpAddr: String with the IP and port address of the condor_startd daemon which is publishing this machine ClassAd. When using CCB, condor_shared_port, and/or an additional private network interface, that information will be included here as well.

State

String which publishes the machine’s HTCondor state. Can be:

"Owner"
The machine owner is using the machine, and it is unavailable to HTCondor.

"Unclaimed"
The machine is available to run HTCondor jobs, but a good match is either not available or not yet found.

"Matched"
The HTCondor central manager has found a good match for this resource, but an HTCondor scheduler has not yet claimed it.

"Claimed"
The machine is claimed by a remote condor_schedd and is probably running a job.

"Preempting"
An HTCondor job is being preempted (possibly via checkpointing) in order to clear the machine for either a higher priority job or because the machine owner wants the machine back.

"Drained"
This slot is not accepting jobs, because the machine is being drained.

TargetType: Describes what type of ClassAd to match with. Always set to the string literal "Job", because machine ClassAds always want to be matched with jobs, and vice-versa.

TotalCondorLoadAvg: The load average contributed by HTCondor summed across all slots on the machine, either from remote jobs or running benchmarks.

TotalCpus: The number of CPUs (cores) that are on the machine. This is in contrast with Cpus, which is the number of CPUs in the slot.

UidDomain: a domain name configured by the HTCondor administrator which describes a cluster of machines which all have the same passwd file entries, and therefore all have the same logins.

VirtualMemory: The amount of currently available virtual memory (swap space) expressed in KiB. On Linux platforms, it is the sum of paging space and physical memory, which more accurately represents the virtual memory size of the machine.

VM_AvailNum: The maximum number of vm universe jobs that can be started on this machine. This maximum is set by the configuration variable VM_MAX_NUMBER.

VM_Guest_Mem: An attribute defined if a vm universe job is running on this slot. Defined by the amount of memory in use by the virtual machine, given in Mbytes.
VM_Memory: Gives the amount of memory available for starting additional VM jobs on this machine, given in Mbytes. The maximum value is set by the configuration variable VM_MEMORY.

VM_Networking: A boolean value indicating whether networking is allowed for virtual machines on this machine.

VM_Type: The type of virtual machine software that can run on this machine. The value is set by the configuration variable VM_TYPE

VMOfflineReason: The reason the VM universe went offline (usually because a VM universe job failed to launch).

VMOfflineTime: The time that the VM universe went offline.

WindowsBuildNumber: An integer, extracted from the platform type, representing a build number for a Windows operating system. This attribute only exists on Windows machines.

WindowsMajorVersion: An integer, extracted from the platform type, representing a major version number (currently 5 or 6) for a Windows operating system. This attribute only exists on Windows machines.

WindowsMinorVersion: An integer, extracted from the platform type, representing a minor version number (currently 0, 1, or 2) for a Windows operating system. This attribute only exists on Windows machines.

In addition, there are a few attributes that are automatically inserted into the machine ClassAd whenever a resource is in the Claimed state:

ClientMachine: The host name of the machine that has claimed this resource

RemoteAutoregroup: A boolean attribute which is True if this resource was claimed via negotiation when the configuration variable GROUP_AUTOREGROUP is True. It is False otherwise.

RemoteGroup: The accounting group name corresponding to the submitter that claimed this resource.

RemoteNegotiatingGroup: The accounting group name under which this resource negotiated when it was claimed. This attribute will frequently be the same as attribute RemoteGroup, but it may differ in cases such as when configuration variable GROUP_AUTOREGROUP is True, in which case it will have the name of the root group, identified as <none>.

RemoteOwner: The name of the user who originally claimed this resource.

RemoteUser: The name of the user who is currently using this resource. In general, this will always be the same as the RemoteOwner, but in some cases, a resource can be claimed by one entity that hands off the resource to another entity which uses it. In that case, RemoteUser would hold the name of the entity currently using the resource, while RemoteOwner would hold the name of the entity that claimed the resource.

PreemptingOwner: The name of the user who is preempting the job that is currently running on this resource.

PreemptingUser: The name of the user who is preempting the job that is currently running on this resource. The relationship between PreemptingUser and PreemptingOwner is the same as the relationship between RemoteUser and RemoteOwner.

PreemptingRank: A float which represents this machine owner’s affinity for running the HTCondor job which is waiting for the current job to finish or be preempted. If not currently hosting an HTCondor job, PreemptingRank is undefined. When a machine is claimed and there is already a job running, the attribute’s value is computed by evaluating the machine’s Rank expression with respect to the preempting job’s ClassAd.

TotalClaimRunTime: A running total of the amount of time (in seconds) that all jobs (under the same claim) ran (have spent in the Claimed/Busy state).

TotalClaimSuspendTime: A running total of the amount of time (in seconds) that all jobs (under the same claim) have been suspended (in the Claimed/Suspended state).

TotalJobRunTime: A running total of the amount of time (in seconds) that a single job ran (has spent in the Claimed/Busy state).

TotalJobSuspendTime: A running total of the amount of time (in seconds) that a single job has been suspended (in the Claimed/Suspended state).

There are a few attributes that are only inserted into the machine ClassAd if a job is currently executing. If the resource is claimed but no job are running, none of these attributes will be defined.

JobId: The job’s identifier (for example, 152.3), as seen from condor_q on the submitting machine.

JobStart: The time stamp in integer seconds of when the job began executing, since the Unix epoch (00:00:00 UTC, Jan 1, 1970). For idle machines, the value is UNDEFINED.

LastPeriodicCheckpoint: If the job has performed a periodic checkpoint, this attribute will be defined and will hold the time stamp of when the last periodic checkpoint was begun. If the job has yet to perform a periodic checkpoint, or cannot checkpoint at all, the LastPeriodicCheckpoint attribute will not be defined.

There are a few attributes that are applicable to machines that are offline, that is, hibernating.

MachineLastMatchTime: The Unix epoch time when this offline ClassAd would have been matched to a job, if the machine were online. In addition, the slot1 ClassAd of a multi-slot machine will have slot<X>_MachineLastMatchTime defined, where <X> is replaced by the slot id of each of the slots with MachineLastMatchTime defined.

Offline: A boolean value, that when True, indicates this machine is in an offline state in the condor_collector. Such ClassAds are stored persistently, such that they will continue to exist after the condor_collector restarts.

Unhibernate: A boolean expression that specifies when a hibernating machine should be woken up, for example, by condor_rooster.

For machines with user-defined or custom resource specifications, including GPUs, the following attributes will be in the ClassAd for each slot. In the name of the attribute, <name> is substituted with the configured name given to the resource.

Assigned<name>: A space separated list that identifies which of these resources are currently assigned to slots.

Offline<name>: A space separated list that indicates which of these resources is unavailable for match making.

Total<name>: An integer quantity of the total number of these resources.

For machines with custom resource specifications that include GPUs, the following attributes may be in the ClassAd for each slot, depending on the value of configuration variable MACHINE_RESOURCE_INVENTORY_GPUs

and what GPUs are detected. In the name of the attribute, <name> is substituted with the prefix string assigned for the GPU.

<name>BoardTempC: For NVIDIA devices, a dynamic attribute representing the temperature in Celsius of the board containing the GPU.

<name>Capability: The CUDA-defined capability for the GPU.

<name>ClockMhz: For CUDA or Open CL devices, the integer clocking speed of the GPU in MHz.

<name>ComputeUnits: For CUDA or Open CL devices, the integer number of compute units per GPU.

<name>CoresPerCU: For CUDA devices, the integer number of cores per compute unit.

<name>DeviceName: For CUDA or Open CL devices, a string representing the manufacturer’s proprietary device name.

<name>DieTempC: For NVIDIA devices, a dynamic attribute representing the temperature in Celsius of the GPU die.

<name>DriverVersion: For CUDA devices, a string representing the manufacturer’s driver version.

<name>ECCEnabled: For CUDA or Open CL devices, a boolean value representing whether error correction is enabled.

<name>EccErrorsDoubleBit: For NVIDIA devices, a count of the number of double bit errors detected for this GPU.

<name>EccErrorsSingleBit: For NVIDIA devices, a count of the number of single bit errors detected for this GPU.

<name>FanSpeedPct: For NVIDIA devices, a value between 0 and 100 (inclusive), used to represent the level of fan operation as percentage of full fan speed.

<name>GlobalMemoryMb: For CUDA or Open CL devices, the quantity of memory in Mbytes in this GPU.

<name>OpenCLVersion: For Open CL devices, a string representing the manufacturer’s version number.

<name>RuntimeVersion: For CUDA devices, a string representing the manufacturer’s version number.
