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

Looking at the web page for POP (http://climate.lanl.gov/Models/POP/
index.shtml), it looks like POP 1.2 is pretty ancient. I gather from
your text that later versions work ok ("POP 2").
My first guess -- knowing nothing about the POP code itself -- is
that there is a bug in the POP 1.2 code such that it is passing a bad
parameter to MPI_CART_SHIFT, and that later versions (POP 2) fixed
the problem.
Do you know if this is the case?

I am having a problem running pop 1.2 (Parallel Ocean Model) with
OpenMPI version 1.1.2 compiled with PGI 6.2-4 on RH EL-4 Update 4
(configure result attached)
The error is as follows:
mpirun -v -np 4 -machinefile node18.dat pop
[node18:11220] *** An error occurred in MPI_Cart_shift

3 additional processes aborted (not shown)
The application runs fine with MPICH 1.2.6 and other applications
(POP 2) run fine with OpenMPI
Any suggestions
Thanks
