Hi Ralph, Since the ticket #4240 has been already set as fixed, I'm sending this email to you. ( I don't konw I could add comments to the fixed ticket)
When I tried to bind the process to l3chace, it didn't work like below: (the host mangae has the normal topology - not inverted) [mishima@manage openmpi-1.7.4]$ mpirun -np 2 -bind-to l3cache -report-bindings ~/mis/openmpi/demos/myprog -------------------------------------------------------------------------- No objects of the specified type were found on at least one node: Type: Cache Node: manage The map cannot be done as specified. -------------------------------------------------------------------------- "-bind-to l1cache/l2cahce" doesn't work as well. At least, I confirmed that the openmpi-1.7.4 works with "-bind-to l3cache". Regards, Tetsuya Mishima
