[Opm] MPI Parallel OPM Flow - SPE 10 Model 2 Hangs

[sindimo]

Hi,

I am running OPM Flow with MPICH MPI on RedHat 7 (installed via yum through
OPM repo, version 2018.04).

I am able to successfully run in parallel  some of the test models  (norne,
spe5, spe9), however spe10model2 always hangs when I try to launch it. It
seems it hangs during the cell partitioning as below. It just partially
does the partitioning on a subset of the processes only (example below
where I have 4 processes and it hangs after doing 2 partitions, I've also
tried with 8 processors and it shows similar behavior). Any help with this
is much appreciated as I need to run SPE10 for some work I am doing, many
thanks!

Sincerely,

Mohamad
