I am running a simple test and using the -bind-to-core or -bind-to-socket options. I think the CPU binding is working fine, but I see these warnings about not being able to bind to memory. Is this expected? This is trunk code (266128)
[dt]$ mpirun --report-bindings -np 2 -bind-to-core connectivity_c -------------------------------------------------------------------------- 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.

I see this on two different clusters. ----------------------------------------------------------------------------------- This email message is for the sole use of the intended recipient(s) and may contain confidential information.
