Request 37GB RAM for this one-slot job qsub -l mem_free37G jobscript Grid Engine will compare to the lower of the two mem_free values on. NAME qconf - Sun Grid Engine Queue Configuration SYNTAX qconf options DESCRIPTION Qconf allows the system administrator to add delete and modify the current Sun Grid Engine configuration including queue management host management complex management and user management.

Random Grid Engine tips and tricks.

Grid engine qconf. You can use the job number to monitor the jobs status and progress within the queue as well see in the next section. Only root or the cluster administrator may modify sge_conf. Qconf allows the system administrator to add delete and modify the current Grid Engine configuration including queue management host management complex management and user management.

Qconf also allows you to examine the current queue configuration for existing queues. 1qconf -aattr queue pe_list dummy allq 2qconf -dattr queue pe_list make allq 3qconf -rattr queue pe_list make allq 4qconf -mattr queue load_thresholds np_load_avg4 allq 5qconf -purge queue slots allqhost 6BONUS. As you can see the default load comes from the compute nodes and are reported in larger intervals configurable in the load_report_time to the master process and hence the scheduler.

To do so make the h_vmem complex consumable and give it a default value that is probably slightly less than the lowest memorycore that you have on execution hosts eg. Qconf -am user-name The -am option add manager adds one or more users to the list of grid engine system managers. Qconf -aattr queue slots host4 allq.

See qconf1 for more details. For more information see the qquota1 and qconf1 man pages. The -cwd option to qsub tells Sun Grid Engine that the job should be executed in the same directory that qsub was called.

Configuration changes can be made globally such that they apply to all cluster hosts or individually. You can see the actual selection in the qstat -j output. Qconf -sh displays the Sun Grid Engine administrative host list nodes that submit jobs.

Qconf -me yourhost hostname yourhost load_scaling NONE complex_values gpu2GPU1 GPU2 Then when requesting -l gpu1 the Univa Grid Engine scheduler will select GPU2 if GPU1 is already used by a different job. Qconf is the command used for most administrativetasks. The last argument to qsub is the command to be executed hostname in this case Notice that the qsub command when successful will print the job number to stdout.

In Grid Engine the load can be set in the load_formula qconf -msconf when load based scheduling is turned on in the queue_sort_method set to load. This HOWTO contains a selection of the most frequently usedoptions. Qstat -F -f -u and then search for mem_free.

See About Hosts and Daemons for more information. The qconf command is used by Altair Grid Engine administrators to display or modify the configuration of the cluster. Altair Grid Engine supports multiple features related to cgroups.

Sge_conf defines the global and local Sun Grid Engine configurations and can be shownmodified by qconf1 using the -sconf-mconf options. By default the root accounts of all trusted hosts are grid engine system managers. To limit resources through the N1 Grid Engine 61 software use the qquota and qconf commands or the QMON graphical interface.

Qconf -sc grep h_vmem h_vmem h_vmem MEMORY. Adding and removing administrative privileges from a host. About Resource Quota Sets.

Common Administrative Tasks for GridEngine. See complex 5 and the definition of memory_specifier. Qconf -ah gives hostadministrative privileges.

Qconf -sel displays the Sun Grid Engine execution host list nodes that run jobs. SYNTAX qconf options DESCRIPTION Qconf allows the system administrator to add delete and modify the current Univa Grid Engine configuration including queue management host management complex management and user management. You can use the -hold_jid option to make jobs run only when other jobs have finished rather than having jobs start and sit waiting for other tasks to complete.

Qconf -sc You can see current values for the execution hosts with qstat -F eg. Resource quota sets enable you to specify the maximum resource consumption for any job requests. The following work with Son of Grid Engine SGE 819 as configured on the University of Sheffields ShARC and Iceberg clusters.
