There is no way for condor to do this. To do this completely would 
require solving the halting problem, which is beyond the scope of our 
research.

In practice, though, there are some approaches that may help. The 
program that tries to execute an instruction which doesn't exist should 
get killed with SIGILL (Illegal instruction). If this program is the 
top-level process in your job (i.e. there is no wrapper script), Condor 
will at least see that the program got a SIGILL, and you can 
administratively do something about that. (Put the job on hold, retry on 
a different machine model number etc.)
