It doesn't appear that that platform is supported yet.

But based on my familiarity with 64-bit Linux you should be able to run 32-bit 
binaries side-by-side with 64-bit ones if you have a properly compiled kernel 
and the right libraries (don't ask me how to configure this, though).  Thus, I 
don't see why you couldn't run 32-bit Condor with 64-bit jobs (at the very least 
vanilla environment jobs).

This is supported by the mailing list traffic:

"If you're not going to use checkpointing, you could probably use the dynamic 
Redhat 9 binaries for IA32 and it should just work. "

Unfortunately, though this poor fellow reports that his "Starter died with a 
SEGFAULT" - I presume on his 64-bit Opteron systems.

The short answer is "I don't know," but it appears as if people are running 
Condor on 64-bit machines.
