Resource Usage

CPU Time

• With limited CPU time, user cares about average solution time

• Measure average CPU time over problems solved
  • Average over all problems ≈ number of problems not solved

Wall Clock Time

• Of direct interest to users

• Measure average wall clock time over problems solved

Memory Use

• Of interest when sharing memory with other processes

• Measure average and maximal footprint

• Excessive memory use increases wall clock times
• Use wall clock limits to limit memory use
