There are a number of batch farms (i.e. collections of compute nodes) located in the NEH and FEH. Depending on your data access you may need to submit jobs to a specific farm, by specifying a specific queue. This can be accomplished by submitting to the appropriate LSF batch queue. Refer to the table below. Multi-core OpenMPI jobs should be run in either the psnehmpiq or psfehmpiq batch queue, see the following section on "Submitting OpenMPI Batch Jobs". Simulation jobs should be submitted to the low priority queues psfehidle and psfehidle.
Experimental Hall | Queue | Nodes | Data | Comments |
---|---|---|---|---|
NEH | psnehq | psana11xx,psana12xx | ana01, ana02 | Jobs <= 6 cores |
| psnehmpiq | psana11xx,psana12xx | ana01, ana02 | OpenMPI jobs > 6 cores, preemptable |
| psnehidle | psana11xx,psana12xx |
| Simulations, preemptable, low priority |
FEH | psfehq | psana13xx,psana14xx | ana11, ana12 | Jobs <= 6 cores |
| psfehmpiq | psana13xx,psana14xx | ana11, ana12 | OpenMPI jobs > 6 cores, preemptable |
| psfehidle | psana13xx,psana14xx |
| Simulations, preemptable, low priority |
The batch farms listed above consist of eighty nodes with the following general specifications:
LSF (Load Sharing Facility) is a job scheduler provided by Platform Computing. It is used at SLAC to execute user batch jobs on the various batch farms. A short list of useful LSF commands follows:
Report status of ALL jobs (running, pending, finished, et cetera) submitted by the current user:
bjobs -w -a
Report only running or pending jobs submitted by user "radmer":
bjobs -w -u radmer
Report running or pending jobs for all users in the psnehq queue:
bjobs -w -u all -q psnehq
Report current node usage on the two NEH batch farms:
bhosts -w ps11farm ps12farm
The following links give more detailed LSF usage information:
