To submit an Abaqus analysis job to all the queues under LSF, please follow the procedure described below, for both serial and parallel runs. In the examples given, we assume that you already have an Abaqus input file, sample.inp created using Abaqus, and it is in the /lsftmp/demo_dir directory that you created and you have permission to write in this directory.
Basic submission procedure
For serial (single processor) runs of Abaqus (for queues ia64, linux and linux64), issue the following commands
prompt:> cd /lsftmp/demo_dir prompt:> abaqus job=sample queue=queue_name
Where queue_name is a suitable queue that can be obtained by checking the appropriate LSF queues with the following commands:
prompt:> bqueues
For more detailed descriptions of each queue:
prompt:> bqueues -l
Please note that due to the difference of OS, you need to be logged into a host of the same platform to submit to the respective queues, i.e.:
-
Itanium systems: queues are ia64 - login to cougar1 or cougar2
-
Linux (Xeon) systems: queues are linux - login to atlas0 or atlas1
-
Linux (EM64T) systems: queues are linux64 - login to atlas2
Specifying a parallel job
The parallel job run submitted to LSF is similar to the serial job, except that an additional flag is used (cpus=N) and an additional step needs to be performed. Create a new text file containing the abaqus submission command:
prompt:> abaqus job=sample queue=queue_name cpus=N
Note that additional LSF options can be placed in the same file prefixed with the #BSUB keyword. Again, the following needs to be observed:
-
Itanium systems: queues are ia64_4p, ia64_large - login to cougar1 or cougar2
-
Linux (Xeon) systems: queues are linux_parallel, linux64_parallel - login to atlas0 or atlas1
-
Linux (EM64T) systems: queue is linux64_parallel - login to atlas2
-
Linux (EM64T) dual-core and quad-core systems: queue is mcore_parallel - login to atlas3-c01
Select the value of N according to the requirements of the queues, for example, for ia64_4p, set cpus=4.
