[Nek5000-users] NEK gets stuck

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

Hi Stefan,

The machine is up now and I checked for the memory usage. The RAM usage is
well within the installed memory. The same problem occurs even with power of
two processors.

How does one toggle the multigrid solver?

Thanks,
Mani
