Re: Profiling COAWST with 2-way coupled ROMS/SWAN

hi john, thanks for this. we've already been tracking the coupling and whether ROMS or SWAN is waiting. It seems the "Unused 03" is related to ROMS waiting. We tried a simple case where there were a total of 180 processors and split them so that swan had 20, 24, and 30. At 30 SWAN and ROMS were ...

Profiling COAWST with 2-way coupled ROMS/SWAN

Dear all, To figure out optimal tiling and processor allocation for a COAWST two-way coupled ROMS & SWAN run, we have been doing some tests and looking at the profile output of the ROMS log. Mostly it is very clear but there is a an item called "Unused 03" which is the largest fraction of time at ...

time-dependent bottom fluxes in roms?

hi all, in the past we've done simulations where we specified constant bottom tracer fluxes in roms via specifying ana_btflux.h. This works great. However, now we want to have time-dependent bottom tracer flux (and fresh water flux) that represents the source of an ocean outfall. These fluxes would ...

output of ROMS memory usage

hi all, i am not sure which category to post this in - so I chose benchmarks. In this ticket, https://www.myroms.org/projects/src/ticket/783 Hernan shows that ROMS can output how much memory is allocated for each grid and tile that works w/ ROMS 3.7 An example of this output is below from Hernan's ...
