Condor is Complementary to Traditional Batch Systems

• Good for backfill and using "spare" CPU cycles.
• Therefore, good for running jobs that can fill gaps flexibly.
• So, jobs which individually do not require great resources, e.g., RAM or diskspace:
  • can run "anywhere";
  • can be checkpointed and migrated easily — requires re-linking.
• Large numbers of small jobs, e.g., parameter sweeps, are ideal.

Sometimes better to use Condor, sometimes SGE. . .
