Hi,

I am working on a cluster and want to run 12 processes for standard Linpack test to measure its performance.

I have made appropriate changes to HPL.dat input file.

However, I need to set OMPI_MCA_ns_nds_vpid and RANK environment variables for execution.

I would be very glad to receive some guidance on values of these variables and their use.

Best Regards,

Aditya Vasal
