nekmpi: Issue on parallel computing

[Ananth Narayan S am24d038]

Hello Nek5000 users

Lately, I have been working on few examples to learn NEK5000. In those case, I mostly use parallel computing, but I have made my own solver for Electrohydrodynamics. Earlier nekmpi was working but I was making few changes (which I couldn't keep track of unfortunately) and nekmpi <caseName> 4 displays as below:

Starting time loop ...

     DT/DTCFL/DTFS/DTINIT   0.150E+02   0.466-309   0.466-309   0.150E+02
Step      1, t= 1.5000000E+01, DT= 1.5000000E+01, C=  0.000 0.0000E+00 0.0000E+00
             Solving for Hmholtz scalars

I wait for atleast 5-10 minutes but no progress further. But upon using serial processing, nek <caseName>, the solver works as expected. I suspect on boundary conditions. You may assume the solution is stable at large time steps.

I would like to know the possible issues, and please let me know for additional information's

Thank you

Ananth.
