Wow, that's quite a .sig. :-)
Open MPI will automatically stripe large messages across however many
NICs you have. So you shouldn't need to use multiple threads.
The threading support in the OMPI v1.2 series is broken; it's not
worth using. There's a big warning in configure when you
Hi everyone,
I have installed openmpi-1.2.3. My system has two ethernet ports. Thus, I am
trying to make use of both ports to speed up the communication process by using
openmp to split into two threads. However, this implementation always cause
error. Then I realized that I need to build
