# Build options for PGI compiler on Linux AMD64 platform
#
# tested with PGI version 10.9 on baudelaire (Linux 2.6.34.7-61.fc13.x86_64), using:
#   -  sh,bash:
#     > export PGI=/srv/software/pgi/pgi-10.9
#     > export PATH=$PGI/linux86-64/10.9/bin:$PATH
#     > export MANPATH=$MANPATH:$PGI/linux86-64/10.9/man
#     > export LM_LICENSE_FILE=$PGI/license.dat
#   - csh,tcsh:
#     > setenv PGI /srv/software/pgi/pgi-10.9
#     > set path=($PGI/linux86-64/10.9/bin $path)
#     > setenv MANPATH "$MANPATH":$PGI/linux86-64/10.9/man
#     > setenv LM_LICENSE_FILE $PGI/license.dat
#
# and tested also with MPI on acesgrid (Fedora Core 15), using:
#       module load pgi     (Version 11.7)
#   and with mpich2:
#       module load mvapich2
#   or  with openmpi:
#       module load openmpi
