Re: [OMPI devel] memory bind warning with -bind-to-core and -bind-to-socket

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 conne
