rough notes on running regression tests on BG

darshan-test/regression/README.BG.txt

+See README.txt for general instructions.  This file contains notes for testing on the Blue Gene platform 
+(more specifically: cetus.alcf.anl.gov).  This example assumes that you are using the MPICH profile conf
+method to add instrumentation.
+
+To run regression tests:
+
+- compile and install both darshan-runtime and darshan-util in the same directory
+  examples:
+
+  # darshan runtime
+  ../configure --with-mem-align=16 --with-log-path=/projects/SSSPPg/carns/darshan-logs --prefix=/home/carns/working/darshan/install-cetus --with-jobid-env=COBALT_JOBID --with-zlib=/soft/libraries/alcf/current/gcc/ZLIB --host=powerpc-bgp-linux CC=/bgsys/drivers/V1R2M2/ppc64/comm/bin/gcc/mpicc
+  make install
+
+  # darshan util
+  ../configure --prefix=/home/carns/working/darshan/install
+  make install
+
+- start a screen session by running "screen"
+  note: this is suggested because the tests may take a while to complete depending on scheduler 
+  availability
+
+- within the screen session, set your path to point to a stock set of MPI compiler scripts
+  export PATH=/bgsys/drivers/V1R2M2/ppc64/comm/bin/gcc:$PATH
+
+- run regression tests
+  ./run-all.sh /home/carns/working/darshan/install-cetus /projects/SSSPPg/carns/darshan-test bg-profile-conf
+  note: the f90 test is expected to fail due to a known problem in the profiling interface for the 
+    F90 MPICH implementation on Mira.
