https://community.intel.com/t5/Intel-MPI-Library/Program-launched-with-mpirun-does-nothing/m-p/977172#M3423 <P>Hi,</P> <P>I have a program (myprogram.exe) that I run with Intel MPI through a queue system (Slurm). This program runs perfectly in some of the nodes, and it does nothing on the rest of the nodes: no program output, no MPI initialization output. I've checked process running when I launch it on different nodes. In the nodes where it works, I can see only one "pmi_proxy" process. In the nodes where it doesn't work I can see (ntasks +1) pmi_proxy process, where ntasks is the number of tasks for mpirun. In the nodes where it works after starting the pmi_proxy, the n myprogram.exe. start. In the nodes where it doesn't work after starting the (ntasks +1) pmi_proxy it blocks.</P> <P>Any suggestion?</P> <P>Regards,&nbsp;</P> <P>Miguel</P> <P></P> Thu, 20 Dec 2012 17:06:14 GMT Miguel_M_ 2012-12-20T17:06:14Z https://community.intel.com/t5/Intel-MPI-Library/Program-launched-with-mpirun-does-nothing/m-p/977172#M3423 <P>Hi,</P> <P>I have a program (myprogram.exe) that I run with Intel MPI through a queue system (Slurm).

Please run again with [plain]-verbose -genv I_MPI_DEBUG 5[/plain] and attach the output as a file (or send it to me directly if you'd prefer it stay private).
