<div dir="ltr">Hi,<br><br> There is no much info available regarding the error. I got this code for benchmarking.

I don't quite understand what the problem here is. It looks like the application is calling MPI_Abort(). MPICH2 kills the processes belonging to the application, when MPI_Abort() is called. Do you expect a different behavior?<br>

Hi All,<br>
<br>
I've compiled a home developed C application, with MPICH2-1.0.7, GNU compilers on Cent OS 5 based Rocks 5 cluster.<br>
<br>
Command used and error are as follows:<br>

$ /opt/mpich2/gnu/bin/mpirun -machinefile ./mach28 -np 8 ./run3 ./<a href="http://run3.in" target="_blank">run3.in</a> <<a href="http://run3.in" target="_blank">http://run3.in</a>> | tee run3_1a_8p<div class="Ih2E3d">

<br>
It is recommended to run this job for 48 and 96 process/cores. But cluster has only 8 cores.<br>
Is this lower no of processes causing the above error?<br>
<br>
Thank you,<br>
