This will be difficult because it happens only with 64 processes and I
am on a cray where I can not run gdb.
I will try to run the same on my quadcore, but am not sure what I get.

Is it possible to replace calls to parmetis with chaco or party for
"internal" usage (and NOT explicit partitioning that I do myself)? Is
it supported/good idea?

Many thanks
