Hello TELEMAC community,

I've recently compiled a parallel installation of TELEMAC using Cygwin, OpenMPI, and gfortran, but cannot successfully launch a simulation in parallel. Below are the listings that are returned when trying to launch validation 037_weirs:

I've also included the configuration file used (compliments of Gourish #8526) as well as some commonly asked for xx.log files.

Any idea why my simulation won't run?

Thank you,
Chris

sebourban OFFLINE Administrator Principal Scientist Posts: 814 Thank you received: 219	It seems to fail on /bin/mpiexec. - Are you sure, it exist ? - Are you sure the service is running (smpd?) ? - Are your sure the credential have been registered ? - I have not yet tried running TELEMAC under cygwin, but should you not have something like /cygdrive/bin/mpiexec ? Hope this helps.

I hadn't initialized/registered the smpd service properly and that was one of my problems. Aside from that, I've switched from OpenMPI (had a hard time tracking down all the auto-install file locations within Cygwin) to MPICH2, compiling from source using the 'gforker' configuration. With that, I am able to successfully run local parallel simulations on my machine using a Cygwin/MPICH2/gfortran/python configuration.

Thank you for the troubleshooting tips.

Best regards,
-Chris
