[svn-r9287] Purpose:
Add recomendation that users add the "-qxlf90=autodealloc" flag to
FFLAGS when building parallel on the IBM SP platform.
Description:
See above.
Solution:
Added the suggestion. Also cleaned up a few minor typos in passing.
Platforms tested:
none needed -- documentatin change only.
Misc. update:
