[MITgcm-support] scalability of high-resolution runs

[Dimitris Menemenlis]

Dear Maura, there is some specific CS50 set-ups available here:
http://mitgcm.org/viewvc/MITgcm/MITgcm_contrib/high_res_cube/code-mods/

I am not aware of publications that describe scalability/speed-up analysis for CS510.
It's really machine dependent.  But CS510 is a relatively small configuration for
modern hardware and scalability is typically near-linear (for high-end, low-latency
hardware) provided you include the overlap regions (and blank tiles, if any)
in your scaling estimates.

If you wanted to aim for even higher-resolution global MITgcm set-ups, there is
a bunch of lat-lon-cap configurations available here:
