Actually, this begs for a questionnaire. I think the list is large and
diverse enough that we can ask actual users as to 1) which generation
of CPUs they are using 2) the amount of nodes they're using 3) whether
single or multiuser jobs 4) what is their problem domain 5) how much
memory 6) which interconnect technology 7) please add here anything
you deem interesting (but please do not let this snowball into Spanish

If anyone is willing to create a webform for this questionnaire/poll
( probably doesn't allow nonmembers to vote), we can also
ask CCL (computational chemistry list), which almost exclusively
consists of users.

Anybody is willing to give it a spin? I think the data would come very
handy for cluster vendors on-list, too.
