Dear Prof. Marks,<div><br></div><div> Thank you very much for your prompt answer.</div><div> I am using openmpi, but I believe that I am facing some of the tricky issues you mentioned. I work in a SMP machine and the calculation starts fine. After some tens of iterations, MPI suddenly asks for a password and everything goes down to the drain.</div>
<div> I am using open mpi 1.6. Do you recommend any older version ??</div><div> All the best,</div><div> Luis Ogando</div><div><br></div><div><br></div><div><br><br><div class="gmail_quote">2013/2/20 Laurence Marks <span dir="ltr"><<a href="mailto:L-marks@northwestern.edu" target="_blank">L-marks@northwestern.edu</a>></span><br>

Some versions of openmpi have problems although that is probably the<br>
best option for the future. There are some tricky issues with openmpi<br>
related to how your flavor of ssh works, there is no standard and some<br>
do not propogate kill commands which means that they can leave<br>
orphans.<br>
<br>
An alternative is mvapich. In a benchmark that I did a few months ago<br>
the Intel mpi was much better for AVX instructions, but that may have<br>
changed.<br>
<br>
Openmpi is easy to compile; mvapich can be a little trickier.<br>
<br>
N.B., if you have fast connections, e.g. infiniband, they are more<br>
than fast enough and I have never seen this as rate limiting with<br>
Wien2k. With ethernet it matters.<br>
