Numbers are in hours
CPUs at CHTC are noticibly slower than CPUs at NRAO. For example, their set of c20xx machines (e20{03..18}) each have two Intel Xeon Silver 4114 2.20GHz processors and 0.5TB to 1TB of memory, while their large memory machines (mem3, mem2001, mem2002) each have four Intel Xeon E7-4820 v4 2.00GHz processors and 2TB to 4TB of memory.

Wallclock time from start to finish for the small data set (test.ms)
- NRAO: 26.5
- NRAO/CHTC: 111.5 so this job spent about as much time waiting for nodes as running
- NRAO/AWS: 27.3
