Big Sinusoidal scaling study

[ian-bertolacci]

Blocked by #3 #1
For #4

Perform scaling study on Ocelote using the 'big' sinusoidal benchmarks.
Ocelote has 2 Xeon Westmere-EP X5650s each with (according to intel's product sheets) has 6 cores each with 2 hyper-threads, for a total of 12 cores and 24 hyper-threads.

Testing should be done to illuminate differences along different paritionings of the cpus (ie, between chip boundaries, and hyper-threads).
A suggested set of thread counts: 1, 2, 4, 6, 8, 12, 16, 24. (@mstrout please comment)

Because time-steps are not parallel, currently suggest 1, maybe 2 time-steps.

Should conduct multiple trials, but because these tests can take over an hour on the high end, will need to be few if any additional trials. (@mstrout please comment)

Deliverables:

• Data package:
  • Raw outputs from each run.
  • Collected data in json format:
    • runtime measured by time or bin/time (either is fine)
    • Per-rank memory as reported by amps memory allocator
    • Note: True OS view of memory occupation is challenging here see issue Report all ranks of ParFlow /proc/status? #7
  • information about parflow software stack.

Done when:

• The data package is considered sufficient, and is uploaded here and probably somewhere else.
