I say atmosphere only, actually these runs are running CLASSIC. From the GAJobs page it look I want mi-ag338 for N96 and mi-ag372 for N216 (both vn10.2).
I'm sure the testing has been done already to establish that two threads is best, but it'll be interesting to see how much better it is
Job is mi-ag338 (N96) for 10 days (on XCE)
so this suggest there isn't much in it, but maybe 2 threads is marginally better (1 thread job is 1.4% slower here).
The job for doing this is mi-ag372.
