Thanks, Jeff
No, I am using the same version of fortran compiler g95, and using mpif77
wrapper. Here is the env used when compiling application.
SYSTEM = g95-lam
COMMENT = g95 Fortran compiler for LAM version of MPI
LAMHG77 = g95
DEFS = -Dmpi -Dg95 -Dg95_lam
FC = mpif77
FC_NOMPI = g95
FFLAGS = -fno-underscoring -O
FFLAGS2 = -fno-underscoring -O
Regards,
Chen
