Q:  I'm compiling a shared library to be used for the NAS Parallel 
Benchmarks.  What do I do?

A:  This works:

        ./wrap.py -f -g -o end2end.c end2end.w
        mpicc -DPIC -fPIC -I.. -DARCH_SANDY_BRIDGE -DARCH_062D -c end2end.c 
        mpicc -shared -Wl,-soname,libend2end.so -o ../lib/libend2end.so ../msr_core.o ../msr_rapl.o ../blr_util.o end2end.o 
        mpicc -L../lib -o harness.end2end harness.c -lend2end

Items of interest:

1)  The flags to wrap.py will generate fortran wrappers and well as re-entry guards.
2)  DPIC must be used along with fPIC.
3)  The above relies on LD_LIBRARY_PATH being correct and it probably shouldn't.
