Error initializing SCOTCH graph.

0 votes

I am running FEniCS 1.6 on centOS6 and get this error with every python code that I try to run in parallel. The code works in serial on the same cluster without error.

*** Error: Unable to partition mesh using SCOTCH.
*** Reason: Error initializing SCOTCH graph.

Dr. Mortensen also experienced this error while testing 1.7 dev version.

Can anyone please guide on how to get rid of this error.

The system admin has attempted a global installation of FEniCS, but he installed 1.6 instead of 2016.

The only solution is to use the ParMETIS mesh partitioner, but what puzzles me is why scotch won't work.

Got some insight here.
