MPICH2 Version: 1.2
MPICH2 Release date: Unknown, built on Mon Oct 19 17:12:54 EDT 2009
MPICH2 Device: ch3:nemesis
MPICH2 configure: --prefix=/home/truedas/local/ --enable-debuginfo
MPICH2 CC: gcc -O2
MPICH2 CXX: c++ -O2
MPICH2 F77: g77 -O2
MPICH2 F90: ifort -O2
So indeed, I have overlooked the g77 entries in the configure log or
searched for the wrong thing, sorry. Why does it choose different
compilers for the two Fortran flavors, and what should I do to make the
Intel compiler work with MPE?
