I forgot to mention that I tried the hello.c version instead of Java and it too failed in a similar manner, but
1. On a single node with --mca btl ^tcp it went up to 24 procs before failing 2. On 8 nodes with --mca btl ^tcp it could go only up to 16 procs On Tue, Mar 11, 2014 at 5:06 PM, Saliya Ekanayake <esal...@gmail.com> wrote: > I just tested with "ml" turned off as you suggested, but unfortunately it > didn't solve the issue. > > However, I found that by explicitly setting --mca btl ^tcp the code worked > on upto 4 nodes with each running 8 procs.
