We have an unusual situation with our updated cluster. We have both 32
bit and 64 bit nodes. But here is what we want to do :
1) Run old 32 bit programs on our new 64 bit nodes (Suse linux 9.1)
2) Run old 32 bit program on our old 32 bit nodes
3) Run recompiled 64 bit programs on our new 64 bit nodes.
We use OpenPBS and our admin has defined an os64 queue for the 64 bit
nodes. The problem we're having is how to define in the users
.bashrc or .cshrc the correct LAM path. We have tried setting the
LAMHOME
environment variable in the PBS submit script, but the .bashrc or
.cshrc don't seem to see the value (its blank). We need to add the
correct LAM to the path so lamboot can find all required routines (like
hboot) and
if we are running 32 bit executables on the 64 bit nodes, we need to add
the 32 bit lam to the path, not the 64 bit lam.
I'm hoping someone here has run into this and can give me some ideas
about
how to solve this.
Thanx,
Bernie Borenstein
