Greetings: I am now seeing the following message for all my calls to mpirun on ompi master. This started with last night's MTT run. Is this intentional?
[rvandevaart@ivy0 ~]$ mpirun -np 1 hostname -------------------------------------------------------------------------- WARNING: a request was made to bind a process. While the system supports binding the process itself, at least one node does NOT support binding memory to the process location. Node: ivy0 This usually is due to not having the required NUMA support installed on the node. In some Linux distributions, the required support is contained in the libnumactl and libnumactl-devel packages. This is a warning only; your job will continue, though performance may be degraded. -------------------------------------------------------------------------- ivy0.nvidia.com On another note, I noticed on both 1.8 and master that we get different number of nodes if we specify the hostname. This is not too big a deal, but surprised me.
