Details:
Line 1 – Just a standard line that needs to be at the top of the file
Line 2 – The -J sets the name of the job, in this case to ANSYS_FLUENT. This doesn’t impact on the job and doesn’t have to be unique. It helps distinguish tasks when looking in squeue (LINK)
Line 3 – This requests you are allocated 1 compute node.
Line 4 – This requests 28 slots on the node. (the full compute node)
Line 5 and 6 – These set the output and error files. The log file will contain Fluent console output, the error file will contain information that may be useful if things don’t work as expected (at a cluster level)
Line 7 – This requests the job runs on one of the compute nodes on the compute queue.
Line 8 – this requests the job runs exclusively on a node i.e (no other jobs)
Line 9 – Comment
Line 10 – Remove all currently running modules
Line 11 – Load Intel MPI module
Line 12- Load Ansys Version 17.2
Line 13 – Turns the Fluent GUI off
Line 14 – Tells fluent where Intel MPI is located
Line 15 – Intel MPI level of error messages
Line 16 – Sets the Omnipath interconnect message protocol
Line 17 – Tells Intel MPI not to fallback to Ethernet
Line 18 - 20 – Checks number of tasks and sets number of processes
Line 21 – Prints Node range to output file
Line 22 – 23 – Prints number of processes to output file
Line 24 – Comment
Line 25 – Produces a hostfile listing nodes to run on
Line 26 – Tells fluent the architecture of the CPU (in this case amd64)</br>
Line 27 – Appends to the library path psm2 library file
Line 28 – This is the run command. Note -i specifies the name of the input journal file
