Jeff,
Thanks for your reply. Yes POP 1.2 is dead w.r.t. development but our
application still uses it. The 1.2 to 2.0 transition
involves a lot of physical differences and for a while at least we are
stuck with 1.2.

Can't say if there is a bug that was fixed since there was a lot of
re-engineering going to 2.0. . But I do know that POP 1.2 works
fine with the MPICH MPI implementation. Wouldn't you expect that a bad
parameters would produce the same error with MPICH?

Thanks much
Axel
