Wow, that's quite a .sig. :-)

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 enab

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 openm
