Convert all global (uncoupled) and regional tests to use quilting restart #1946
Conversation
Regression test passed one Hera: |
I'm curious. Why aren't you making this change to the coupled tests? |
@junwang-noaa suggested that at this point we should only change uncoupled tests. |
I trust her judgement, but I'm still curious about the reason. If she's willing to share it, I'd be grateful. |
@SamuelTrahanNOAA The purpose of the moving restart writing from forecast to write grid component is to save forecast time. In the coupled configuration, only fv3 is using write grid component while other components are still doing IO on the forecast grid component. So at restart time even though fv3 can move on with forecast but it has to wait for other components to finish writing their restart files, some of which may take longer time than fv3. Also for the higher resolution case than C96, writing restart files may require increase write group since now write grid comp takes longer time to finish. So we won't get speed up |
Ah, well, perhaps one day the other coupled components will have quilt servers, too. |
@DusanJovic-NOAA we are considering to combine in #1972 (mom6 update) and #1974 (upp hash update) to this pr. All no baseline change. Can you combine in those PRs? |
Done. |
I added code change, so we can resolve issue 1440 when this PR is merged. |
Looks good after those changes, thanks! |
My mistake on the review requests, sub prs still need to get merged in. |
The FV3 PR is already approved. Someone needs to press the Merge button. |
@jiandewang All test are done. Can you merge in the MOM6 pr? |
NOAA-EMC/fv3atm#713 was merged |
just merged
|
MOM6 PR was merged as well: NOAA-EMC/MOM6@a36cb73 |

Description
All global (uncoupled) and regional test are converted to use quilting restart. Two regression tests, one global (control_p8) and one regional (hrrr_control) are also running with FMS I/O restart in addition to quilting restart. All other tests that are currently running quiting restart (tests with '_qr' in the name) are removed.
