Would a better solution be something like: char default_credential[8] = "12345"; char *bar = strdup(default_credential) ? On May 22, 2014, at 12:52 AM, George Bosilca wrote: > This is more subtle that described here. It's a vectorization problem > and frankly it should appear on all loop-base

2014-05-22 Thread Bibrak Qamar
Hi, I am facing problem in running Open MPI using TCP (on 1G Ethernet). In practice the bandwidth must not exceed 1000 Mbps but for some data points (for point-to-point ping pong) it exceeds this limit. I checked with MPICH it works as desired. Following is the command I issue to run my program o
