[mpich-discuss] NASA NAS Paralllel Benchmarks

[chan at mcs.anl.gov]

Your CompileFT.out shows that you are using NAS 2.4 and your mpif77
is compiled with g77 which seems to complain that 2 common blocks
ucom and sumcomm are too large.  If you want to continue using NAS 2.4
and g77, you may want to try 1) decrease your problem size, i.e. class size,
2) find some way (compiler options) to tell g77 or the linker to allow
bigger common block. 3) or use some other fortran compiler, like gfortran
or ifort, see if they allow bigger common block (I think we do our
nightly testing with NAS 3.3 with gfortran with no problem, but don't
know what size of the problem we tested.)
