<p dir="ltr">Dear Luis,</p>
<p dir="ltr">It looks like the problem is not in Wien2k. I would recommend to make sure that you can get a list of host names correctly before proceeding with wien. There are slight difference between various mpi implementation in a way of passing the host name list.</p>

<br>
Can you run other MPI codes under SGI scheduler on your cluster? In any case, I would suggest first to try the simplest check<br>
<br>
mpiexec -n $NSLOTS hostname<br>
<br>
this is what we use for Wien2k<br>
<br>
mpiexec -machinefile _HOSTS_ -n _NP_ _EXEC_<br>
<br>
the next line is also useful to ensure a proper CPU load<br>
<br>
setenv MV2_ENABLE_AFFINITY 0<br>
<br>
<br>
I hope this will help<br>

Dear WIEN2k community,<br>
<br>
I am trying to use WIEN2k 12.1 in a SGI cluster. When I perform<br>
parallel calculations using just "one" node, I can use mpirun and<br>
everything goes fine (many thanks to Prof. Marks and his SRC_mpiutil<br>
directory).<br>
On the other hand, when I want to use more than one node, I have to<br>
use mpiexec_mpt and the calculation fails. I also tried the mpirun for<br>
more than one node, but this is not the proper way in a SGI system and I<br>
did not succeed.<br>
Well, I would like to know if anyone has experience in using WIEN2k<br>
with mpiexec_mpt and could give me any hint.<br>
I can give more information. This is only an initial ask for help.<br>
All the best,<br>
Luis<br>
<br>
