Any jobs you submit will have a default requirements expression to
say "require the same OS and Arch as the submit machine". x86_64 machines
have a different Arch than IA32 machines. 

If that's the case, jobs will never match with the IA32 machines, and 
they'll always stay idle.

You can check this by:

1. condor_q -analyze will tell you what how many machines match and how
many don't match.

2. You can check the negotiator log on the central manager to see how
many machines it is considering for matchmaking. 

3. You can check the schedd log on the submit machine to see if you're
running into some problem that prevents running new jobs.
