We've been through the mill on the 32 vs 64 bit issues in our group meetings
here too many times. It comes down to the fact that we need 64 bit
applications, but the only way that we could do it was as a new head node. An
ugly compromise, but way above my pay-grade.
I have a wrapper shell script that does add -m32 to compiler commands that don't
already have -m64 on them, but I don't trust it to be bulletproof when
interacting with more complex drivers like mpicc. My question is based on the
way that the automake tools do pick up certain flags from the environment when
building LAM-MPI and embed them into the mpicc wrappers. It would seem like
there ought to be a way to expand that set. I'm sure it could be done in the
source, but it would be nice to see if a short-cut exists.
Thanks,
Andy
