[CIG-MC] pgi compilers

[Bianco, Todd]

Hello All,

To Walter: The /etc/redhot-release is CentOS 4.5, so Redhat 4.X, I suppose.

I have the code compiled and running using OpenMPI built on PGI compilers,
but I have to add

#define NULL 0

to Parsing.c and Pan_problems_misc_functions.c. Adding the new definition of
NULL in global_defs.h will cause other parts of the code to generate errors.


I have not tested the code thoroughly for unintended behavior, but I
compared a two parallel runs, one using MPI built on GNU and one using MPI
built on PGI compilers. There are only very small differences between the
output of the different runs, which may be do to the randomization of tracer
locations in the version I use. For example comparing the vertical velocity
field between the two runs, there is a difference of <0.001% in some
locations. I will write to you if I notice any strange behavior with the PGI
compiler, or with the different definitions of NULL.

Regards,
Todd
