Orion is built on RedHat Enterprise Linux ver. 6 with the Rocks Cluster distribution. This combination allows us to harness the power of the hardware we have, maintain broad-based software compatibility and ease administration of the system.

Compute jobs are distributed to the processing systems by way of Torque and Maui. For some pointers on setting up your workload for Torque/Maui, please see the Torque Wiki. You can also reference the Rocks-provided documentation.

More basic information about Torque/PBS can be found at the following sites

Submitting a Abaqus job to the cluster is a little different than how you traditionally submit a job. Instead of creating and submitting a bash script via qsub you will use the "abaqus" command. When you run the abaqus command it will create all the output files in the directory you ran the command from. It is strongly suggested that you create a new directory for each job being submitted.

Create a test job

   Create an test input file
       * abaqus fetch -j e4
   Run abaqus with the proper settings
       * abaqus -j e4testjob memory="24 gb" -input e4.inp -cpus 24 -queue production.q:wall2560

example:    abaqus -j JobName memory="24 gb" -input INPUT_FILE.inp -cpus 36 -queue production.q:wall50400

Command Arguments

-j           =>  Job Name
memory  =>  Amount of allocated RAM
-input     =>  The input file
-cpus     =>  Amount of CPUs
-queue   =>  Queue name
:wall      =>  Walltime in minutes
