Using PBS, you can give the opterons the "64bit" property, and then
64-bit jobs can ask for "64bit" nodes.

The IBM e325 is a rack-mount Opteron. Sun's V20z is a rack-mount. The
HP ProLiant DL145 and DL585 are rack-mounts. Those are all top-tier
vendors. In the 2nd tier, pretty much all the vendors have rack-mount
Opterons.
