One warning I get with I_MPI_DEBUG set to 5 is this odd one:
[0] MPID_nem_ofi_init(): cannot load default ofi library libfabric.so, error=libfabric.so.1: cannot open shared object file: No such file or directory
I *THINK* this is saying we don’t have the OFI library installed. Is this something to worry about or just ignore it?
Would OFI give any performance benefit on Omni-Path fabric? What little I know is that OFI helps with portability but nothing else.
