+#######################
+
+# Script to set up the environment for tests on this platform.  Must export
+# the following environment variables:
+# 
+# DARSHAN_CC: command to compile C programs
+# DARSHAN_CXX: command to compile C++ programs
+# DARSHAN_F90: command to compile Fortran90 programs
+# DARSHAN_F77: command to compile Fortran77 programs
+# DARSHAN_RUNJOB: command to execute a job and wait for its completion
+
+# This script may load optional modules (as in a Cray PE), set LD_PRELOAD
+# variables (as in a dynamically linked environment), or generate mpicc
+# wrappers (as in a statically linked environment).
+
+# Notes specific to this platform (workstation-dynamic)_
+########################
+# This particular env script assumes that mpicc and its variants for other 
+# languages are already in the path, and that they will produce dynamic
+# executables by default.  Test programs are compile usign the existing
+# scripts, and LD_PRELOAD is set to enable instrumentation.
+
+# The runjob command is just mpiexec, no scheduler
+
+export DARSHAN_CC=mpicc
+export DARSHAN_CXX=mpicxx
+export DARSHAN_F77=mpif77
+export DARSHAN_F90=mpif90
+FULL_MPICC_PATH=`which mpicc`
+
+# This is a hack.  In order to instrument Fortran programs with LD_PRELOAD,
+# we must prepend libfmpich.so to the LD_PRELOAD variable, but with a fully
+# resolve path.  To find a path we locate mpicc and speculate that
+# libfmich.so can be found in ../lib.
+export LD_PRELOAD=`dirname $FULL_MPICC_PATH`/../lib/libfmpich.so:$DARSHAN_PATH/lib/libdarshan.so:$LD_PRELOAD
