Hi Folks, I just now subscribed to the hwloc user mail list, but I suspect that requires human intervention to get on, and that might not mean something happening till next week.
Alas google has failed me in helping to understand the message. So, I decided to post to Open MPI devel list and see if I get a response. Here's what I see with with Open MPI 2.1.1: srun -n 4 ./hello_c Invalid knl_memoryside_cache header, expected "version: 1". Invalid knl_memoryside_cache header, expected "version: 1". Invalid knl_memoryside_cache header, expected "version: 1". Invalid knl_memoryside_cache header, expected "version: 1".

Thanks for any help, Howard
