Default walltime too short on Gaea? #206

Closed climbfuji closed 4 years ago

climbfuji commented 4 years ago

When running a C768 case on gaea, I need issue the following sequence of commands. I believe these are all expected except the adjustment of the walltime for the actual model run. Can we set the default walltime to 1 hour on gaea? The debug queue on gaea has a walltime limit of 1 hour, i.e. no changes required to the queue configuration.

./cime/scripts/create_newcase --case GFSv16betaC768 --compset GFSv16beta --res C768 --workflow ufs-mrweather
cd GFSv16betaC768/
./case.setup 2>&1 | tee log.setup
./case.build 2>&1 | tee log.build
./xmlchange STOP_OPTION=nhours
./xmlchange STOP_N=24
./case.submit 2>&1 | tee log.submit

@uturuncoglu Can you make this update?

uturuncoglu commented 4 years ago

@ligiabernardet @climbfuji of course we could set a default value for it but it requires CIME PR. You could also adjust them using following commands easily,

./xmlchange JOB_WALLCLOCK_TIME=00:30:00
./xmlchange USER_REQUESTED_WALLTIME=00:30:00

So, if you still need it (and also other changes in CIME side if you need), let me know.

I don't know what is better, updating CIME again (it hasn't been tagged yet anyway) or adding more documentation.

uturuncoglu commented 4 years ago

@climbfuji since it is one line command, i think that we could add it to the doc and note but it is up to you.

ligiabernardet commented 4 years ago

OK, we can add it to the documentation. I think a FAQ would work - unless you have a better idea.

Since we are talking about this, could you explain why two variables are needed to change the wall clock? What is the difference between JOB_WALLCLOCK_TIME and USER_REQUESTED_WALLTIME, and under what circumstances would they have different values?

@ligiabernardet Sorry for the confusion. We just need to change the JOB_WALLCLOCK_TIME.

ligiabernardet commented 4 years ago

@uturuncoglu What is USER_REQUESTED_WALLTIME?

uturuncoglu commented 4 years ago

@ligiabernardet USER_REQUESTED_WALLTIME is an internal value that should not be changed by the user. it's just used internally to keep track. Sorry for confusion.

ligiabernardet commented 4 years ago

@panll Can you please add this FAQ and remove USER_REQUESTED_WALLTIME from User's Guide?
