[Pvfs2-developers] Using MPE with BMI?

[Scott Atchley]

Ok, I got this working. I had to recompile mpich2 with CFLAGS="- 
DCLOG_NOMPI", add "-lmpe-nompi" to bmx_mx's LIBS in Makefile.in and  
then rerun PVFS2's configure, make and make install.

I am now trying to find a Java that will let me view the log. :-P
