Ocean Modeling Discussion

Both grids are large. The nest has a refinement factor of 3.
Parent grid rho points: 556 x 541
Nested grid rho points: 542 x 407

I was running on a single node with 16 processors (4x4). I removed TIME_INTERP_FLUX and the timing has remained approximately the same. Thank you for you help!

Hi all,
Thank you for your response. I have run the same model using both 2-way and 1-way nesting. The 1-way nesting code does not seem to speed up the model run time very much.

# time steps # of nodes run time
(16 cpu/node)
2-way nesting 100 1 ~ 54 min
1-way nesting 100 1 ~ 52 min

Is anyone ...

Hi all,
I am running an online nesting configuration and finding a tremendous slow-down in computational speed when transitioning from offline to online nesting. Here are some numbers I have calculated:


Run # of time steps # of nodes Total run time
(16 cores per node)
Parent grid 1000 1 ~ 37 min ...
