# On one p690 run, we have these two results: 
#           Temperature calculations    4243.5252    426.0988      0.0117
#           Temperature calculations     336.4992     32.3458      0.0077
# The difference being 
#  1. number of processors: 4 and 16
#  2. the compile flags: debug and speed
# Also, the first run quit sooner; i.e. at a different place
# The first run stopped on a floating point overflow
# The second run stopped on a seg fault.
#
# -qsave is the default for Fortran77, -qnosave for Fortran90
# take -qextchk out for the final compile
# Need -qhalt=s, else the compiler stops on the multiple errors from MPI calls.
