LSB_AFFINITY_HOSTFILE not set #18

Hi, I am using LSF on LLNL's Lassen cluster. Link is https://hpc.llnl.gov/hardware/compute-platforms/lassen. The script seems to require the environment variable LSB_AFFINITY_HOSTFILE to be set. But, this environment variable is not set on Lassen. My software engineering expertise and LSF knowledge is extremely limited. If you can help define and describe it, I can try contacting our local experts to find an appropriate equivalent setting on Lassen.

Thank you very much for any help.
