Just to chime in, this is something that we're suffering with here at ERDC as well..<br><br>The new Cray XT3 we've setup operates with 2 OS's: The main login nodes (Where everything is compiled) runs SUSE Linux. The trick is that jobs that want to make use of all 4096 processors have to run distributed across the Catamount nodes, which is not Linux compatible (not even close, honestly). The way to compile for those nodes (in my feeble understanding of things) is to use the same compiler but add a -catamount option. This has given us alot of headaches here as stuff compiled for catamount won't run on the login nodes, and vice versa.
<br><br>So, VTK/Cmake is currently restricted to login/interactive nodes only. So any steps made toward separating "target" and "build" Architectures would be extremely valuable in this regard :)<br><br>
