Dear Eric, David,
I have install gromacs on Compaq Alpha SC45 here (42 nodes each node
with 4cpu).
It works well for small system.
But when my system is increased to 61K , problems happens
Fatal error: calloc for fr->vdwtab (nelem=204864, elsize=8, file
force.c, line 750): Not enough space
Error on node 1, will try to stop all the nodes

What's your ideas?
I test memory with command limit, it turns out:

cputime         unlimited
filesize        unlimited
datasize        4194304 kbytes
stacksize       3465214 kbytes
coredumpsize    0 kbytes
memoryuse       4089768 kbytes
vmemoryuse      4194304 kbytes
descriptors     4096
