Hi Russ,

For starters, I always compile with the "_r" compilers, for
threadf-safe code, i.e.  "xlc_r", "xlf_r", etc.  I use the same flags
for blackforest and bluesky, but I use the "qarch=auto" option so that
it optimizes the build for the particular architecture (bluesky is a
power 4 and blackforest is a power 3, and "-qarch=auto" will detect
this automatically). That said, here are the flags I use for 64-bit
and 32-bit builds. The main difference between the two is the
"-bmaxdata:2000000000 -bmaxstack:256000000" option which is needed for
32 bit:

setenv OBJECT_MODE 64
setenv CC xlc_r
setenv CPPFLAGS -DNDEBUG
setenv CFLAGS '-O -D_LARGE_FILES -O -qmaxmem=-1 -qarch=auto'
setenv FC xlf_r
setenv FFLAGS '-O -qarch=auto'
setenv F90 xlf90_r
setenv F90FLAGS '-O -qsuffix=f=f90 -qmaxmem=-1 -qarch=auto'
setenv CXX xlC_r
setenv CXXFLAGS '-O -D_LARGE_FILES -O -qmaxmem=-1 -qarch=auto'


setenv OBJECT_MODE 32
setenv CC xlc_r
setenv CPPFLAGS -DNDEBUG
setenv CFLAGS '-D_LARGE_FILES -O -qmaxmem=-1 -qarch=auto -bmaxdata:2000000000 
-bmaxstack:256000000'
setenv FC xlf_r
setenv FFLAGS '-O -qarch=auto -bmaxdata:2000000000 -bmaxstack:256000000'
setenv F90 xlf90_r
setenv F90FLAGS '-qmaxmem=-1 -qsuffix=f=f90 -qarch=auto -bmaxdata:2000000000 
-bmaxstack:256000000'
setenv CXX xlC_r
setenv CXXFLAGS '-D_LARGE_FILES -O -qmaxmem=-1 -qarch=auto -bmaxdata:2000000000 
-bmaxstack:256000000'
