[Nek5000-users] Simulation hanging at 'mapping elements to processors'

[nek5000-users at lists.mcs.anl.gov]

Hello,

I am trying to run a simulation that has ~500,000 elements on 1280 processors with lx1=4 for debugging purposes. My simulation hangs after outputting 'mapping elements to processors’. I generated the mesh with Cubit and then used the exo2nek script to get the re2 file. Genmap runs fine on the re2 file.

I was wondering if this problem has been encountered in the past, and what I could do to fix it.

Thanks,
Marco
