Resource Manager Extensions

• Resource Manager Extension Specification
• Resource Manager Extension Values
• Resource Manager Extension Examples

All resource managers are not created equal. There is a wide range in what capabilities are available from system to system. Additionally, there is a large body of functionality that many, if not all, resource managers have no concept of. A good example of this is job QoS. Since most resource managers do not have a concept of quality of service, they do not provide a mechanism for users to specify this information. In many cases, Moab is able to add capabilities at a global level. However, a number of features require a per job specification. Resource manager extensions allow this information to be associated with the job.

Resource Manager Extension Specification

Specifying resource manager extensions varies by resource manager. TORQUE, OpenPBS, PBSPro, Loadleveler, LSF, S3, and Wiki each allow the specification of an extension field as described in the following table:

Resource Manager	Specification Method	Example
TORQUE 2.0+	-l	> qsub -l nodes=3,qos=high sleepy.cmd
TORQUE 1.x/OpenPBS	-W x=	> qsub -l nodes=3 -W x=qos:high sleepy.cmd OpenPBS does not support this ability by default but can be patched as described in the PBS Resource Manager Extension Overview.
Loadleveler	#@comment	#@nodes = 3 #@comment = qos:high
LSF	-ext	> bsub -ext advres:system.2
PBSPro	-l	> qsub -l advres=system.2 Use of PBSPro resources requires configuring the server_priv/resourcedef file to define the needed extensions as in the following example: advres type=string qos type=string sid type=string sjid type=string
Wiki	comment	comment=qos:high

Resource Manager Extension Values

Using the resource manager specific method, the following job extensions are currently available:

ADVRES
Format:	[<RSVID>]
Default:	---

GRES and SOFTWARE
Format:	comma delimited list of generic resources where each resource is specified using the format <RESTYPE>[{+|:}<COUNT>][@<TIMEFRAME>]
Default:	---
Description:	Indicates generic resources required by the job on a per task basis. If a <COUNT> is not specified, the resource count defaults to 1. If the <TIMEFRAME> is specified, the generic resource is consumed from the start of the job until <TIMEFRAME> expires; otherwise the resource is consumed during the entire life of the job.
Example:	> qsub -W x=GRES:tape+2,matlab+3@2:00 testj.txt Note: When specifying more than 1 generic resource with -l the '%' character must be used to deliminate them. > qsub -l gres=tape+2%matlab+3 testj.txt > qsub -l software=matlab:2 testj.txt

Default:	---
Description:	Specifies how node resources should be accessed. (See Node Access Policies for more information). Note: The naccesspolicy option can only be used to make node access more constraining than is specified by the system, partition, or node policies. If the effective node access policy is shared, naccesspolicy can be set to singleuser, if the effective node access policy is singlejob, naccesspolicy can be set to singletask.
Example:	> qsub -l naccesspolicy=singleuser bw.cmd > bsub -ext naccesspolicy=singleuser lancer.cmd Job can only allocate free nodes or nodes running jobs by same user.

Default:	FALSE
Description:	Specifies that the requested nodecount should be treated as a requested node equivalency amount.
Example:	> qsub -l nodes=2000 -W x=NODESCALING:TRUE Job will run on the equivalent of 2000 nodes (meaning the job may run on fewer nodes if the nodes are faster and vice versa).
NODESET
Format:	<SETTYPE>:<SETATTR>[:<SETLIST>]
Default:	---
Description:	Specifies nodeset constraints for job resource allocation. (See the NodeSet Overview for more information.)

Example:	> qsub -l nodesetdelay=300,walltime=16000 bw.cmd
NODESETISOPTIONAL
Format:	<BOOLEAN>
Default:	---
Description:	Specifies whether the nodeset constraint is optional. (See the NodeSet Overview for more information.) Requires SCHEDCFG[] FLAGS=allowperjobnodesetisoptional

Example:	> qsub -l nodes=1,partition=math:geology The job must only run in the math partition or the geology partition.
PREF
Format:	[{feature|variable}:]<STRING>[:<STRING>]... If feature or variable are not specified, then feature is assumed
Default:	---
Description:	Specifies which node features are preferred by the job and should be allocated if available. If preferred node criteria are specified, Moab favors the allocation of matching resources but is not bound to only consider these resources. Preferences are not honored unless the node allocation policy is set to PRIORITY and the PREF priority component is set within the node's PRIORITYF attribute.
Example:	> qsub -l nodes=1,pref=bigmem The job may run on any nodes but prefers to allocate nodes with the bigmem feature.
QoS
Format:	<STRING>
Default:	---
Description:	Requests the specified QoS for the job.
Example:	> qsub -l walltime=1000,qos=highprio biojob.cmd
QUEUEJOB
Format:	<BOOLEAN>

Default:	---
Description:	Indicates required node attributes.
Example:	> qsub -l reqattr=matlab=7.1 testj.txt
RESFAILPOLICY
Format:	one of CANCEL, HOLD, IGNORE, NOTIFY, or REQUEUE
Default:	---

Example:	resfailpolicy=ignore For this particular job, ignore node failures.
RMTYPE
Format:	<STRING>
Default:	---
Description:	One of the resource manager types currently available within the cluster or grid. Typically, this is one of PBS, LSF, LL, SGE, SLURM, BProc, and so forth.
Example:	rmtype=ll Only run job on a Loadleveler destination resource manager.
SIGNAL
Format:	<INTEGER>[@<OFFSET>]
Default:	---
Description:	Specifies the pre-termination signal to be sent to a job prior to it reaching its walltime limit or being terminated by Moab. The optional offset value specifies how long before job termination the signal should be sent. By default, the pre-termination signal is sent one minute before a job is terminated
Example:	> msub -l signal=32@120 bio45.cmd
SPRIORITY
Format:	<INTEGER>
Default:	0
Description:	Allows Moab administrators to set a system priority on a job. (similar to setspri)
Example:	> qsub -l nodes=16,spriority=100 job.cmd
TASKDISTPOLICY
Format:	RR or PACK
Default:	---
Description:	Allows users to specify task distribution policies on a per job basis. (See Task Distribution Overview)
Example:	> qsub -l nodes=16,taskdistpolicy=rr job.cmd

Default:	0
Description:	Specifies the time at which Moab should cancel a queued or active job. (See Job Deadline Support.)
Example:	> msub -l nodes=10,walltime=600,termtime=12:00_Jun/14 job.cmd
TPN
Format:	<INTEGER>[+]
Default:	0
Description:	Tasks per node allowed on allocated hosts. If the plus (+) character is specified, the tasks per node value is interpreted as a minimum tasks per node constraint; otherwise it is interpreted as an exact tasks per node constraint. Note on Differences between TPN and PPN: There are two key differences between the following: (A) qsub -l nodes=12:ppn=3 and (B) qsub -l nodes=12,tpn=3 The first difference is that ppn is interpreted as the minimum required tasks per node while tpn defaults to exact tasks per node; case (B) executes the job with exactly 3 tasks on each allocated node while case (A) executes the job with at least 3 tasks on each allocated node—nodeA:4,nodeB:3,nodeC:5 The second major difference is that the line, nodes=X:ppn=Y actually requests X*Y tasks, whereas nodes=X,tpn=Y requests only X tasks.
Example:	> msub -l nodes=10,walltime=600,tpn=4 job.cmd
TRIG
Format:	<TRIGSPEC>
Default:	---
Description:	Adds trigger(s) to the job. (See the Trigger Specification Page for specific syntax.) Job triggers can only be specified if allowed by the QoS flag trigger.

Example:	> msub -l trl=2@500:4@250:8@125:16@62 job.cmd or > qsub -l trl=2:3:4
TRL (Format 2)
Format:	<INTEGER>-<INTEGER>
Default:	0
Description:	Specifies a range of task requests that require the same walltime. (See Malleable Jobs.)
Example:	> msub -l trl=32-64 job.cmd For optimization purposes Moab does not perform an exhaustive search of all possible values but will at least do the beginning, the end, and 4 equally distributed choices in between
TTC
Format:	<INTEGER>
Default:	0
Description:	Total tasks allowed across the number of hosts requested. TTC is supported in the Wiki resource manager for SLURM. Compressed output must be enabled in the moab.cfg file. (See SLURMFLAGS for more information). NODEACCESSPOLICY should be set to SINGLEJOB and JOBNODEMATCHPOLICY should be set to EXACTNODE in the moab.cfg file.
Example:	> msub -l nodes=10,walltime=600,ttc=20 job.cmd In this example, assuming all the nodes are 8 processor nodes, the first allocated node will have 10 tasks, the next node will have 2 tasks, and the remaining 8 nodes will have 1 task each for a total task count of 20 tasks
VAR
Format:	<ATTR>:<VALUE>
Default:	---
Description:	Adds a generic variable to the job.
Example:	VAR=applicationtype:blast

Resource Manager Extension Examples

If more than one extension is required in a given job, extensions can be concatenated with a semicolon separator using the format <ATTR>:<VALUE>[;<ATTR>:<VALUE>]...

Example 1

#@comment="HOSTLIST:node1,node2;QOS:special;SID:silverA"

Job must run on nodes node1 and node2 using the QoS special. The job is also associated with the system ID silverA allowing the silver daemon to monitor and control the job.

Example 2

# PBS -W x=\"NODESET:ONEOF:NETWORK;DMEM:64\"

Job will have resources allocated subject to network based nodeset constraints. Further, each task will dedicate 64 MB of memory.

Example 3

>  qsub -l nodes=4,walltime=1:00:00 -W x="FLAGS:ADVRES:john.1"

Job will be forced to run within the john.1 reservation.
