Mixing Athlons and Opterons

[wacki]

Is it possible to have a cluster that has nodes from Althon computers and Opteron based computers and access them as a whole, or access them seperately depending on if you need 64 bit computing or not?\

Example:
You have a cluster with 20 dual athons and 20 dual Opterons.

You are running Blast (a 32 bit program) it runs on all 40 computers.

Then you run Bayes (needs 64 bit computing) it runs on the 20 Opterons only.

Maybe you're better of with posting this in the CPU/processor or Operating System forum

Ya, it looks like no one is going to answer. Thx for advice.

I don't think that it's nobody answering. I guess nobody just knows!

I think if you had a system like Mosix, you could set up two separate clusters, but if you ran a 32 bit app, you'd have to find a way to distribute it over both clusters (very hard, maybe not possible), or just run two separate copies (may or may not work depending on the app and what it's designed to do).
