Thanks for all the replies so far (public and private). Just to clarify:
the argument is Compaq Tru64 vs linux for a large (~1000 node) cluster of
alphas. NT is not in the running, so old ammo from the desktop wars
won't help here.
What I'm looking for is someone who is running a large number of nodes and
has gathered statistics reflecting the average number of system crashes over
time. Obviously this depends on hardware, workload, power, etc.; however
a good MTBF for any cluster of linux systems would help build a little
Simply pointing to the many large HPC linux clusters in use all over the
world, or even at other U.S. energy labs apparently isn't convincing enough.
