01:13 <weilewei> Though I search around, is there any way to use make test to run one particular test? In ctest, I can use ctest -R test_name, the regular expression

01:16 <hkaiser> weilewei: sure

01:16 <hkaiser> make targetname, where targetname is whatever is defined in the cmakefiles, should autocomplete

01:18 <hkaiser> i.e. make test.unit.lcos.apply_local or somesuch

01:20 <weilewei> bash-4.2$ make tests.regressions.modules.collectives.distributed.mpi.multiple_gather_ops_2001make: *** No rule to make target `tests.regressions.modules.collectives.distributed.mpi.multiple_gather_ops_2001'. Stop.

01:21 <weilewei> I had this problem...

01:22 <weilewei> but i can

01:22 <weilewei> make tests.unit.modules.affinity.parse_affinity_options

01:22 <hkaiser> weilewei: yah, don't write "mpi." this is not part of the target name

01:24 <weilewei> If I skip mpi, it is still no rule to make target.. I guess more portions of the name need to skip?

01:26 <hkaiser> weilewei: here: https://github.com/STEllAR-GROUP/hpx/blob/master/libs/collectives/tests/regressions/CMakeLists.txt#L36

01:26 <hkaiser> this means that your target has the name tests.regression.modules.collectives.multiple_gather_ops_2001

01:27 <hkaiser> or test. (no 's')

01:27 <hkaiser> no, it's tests.

01:28 <hkaiser> see here https://github.com/STEllAR-GROUP/hpx/blob/master/cmake/HPX_AddTest.cmake#L177 and here https://github.com/STEllAR-GROUP/hpx/blob/master/cmake/HPX_AddTest.cmake#L163

01:32 <weilewei> aha, make tests.regressions.modules.collectives.multiple_gather_ops_2001 is the correct one

01:33 <weilewei> however, `make sometest` just builds the target but not run it. `make test` actually runs test

01:34 <hkaiser> weilewei: you can't just run a single test, I believe

01:35 <weilewei> Ok, I cannot then

01:35 <weilewei> I can only use ctest -R some_test to run

01:35 <hkaiser> weilewei: but you can use hpxrun.py to run things manually

01:35 <hkaiser> yah, that should work as well

01:35 <weilewei> It occurs strange to me, some mpi tests pass when I am on an interactive node, but not pass when I submit the job directly

01:36 <hkaiser> how do they fail?

01:36 <weilewei> hkaiser that's what i use

01:37 <weilewei> https://gist.github.com/weilewei/c87ad87b42244244b12ece27a81a3ace

01:37 <hkaiser> that's a matter of how you request the node from the system

01:38 <hkaiser> apparently it gives you just one core

01:39 <weilewei> One core? I need to adjust it

01:41 <weilewei> Oh, I `#BSUB -alloc_flags smt1` simultaneous multithreading level to 1

01:42 <weilewei> Also, I wish to have jsrun option added to runwrapper in hpx, but how can the parser pick up jsrun from system environment automatically? I am willing to try a PR for this file: https://github.com/STEllAR-GROUP/hpx/blob/c36107e13c47ff6a4ea91c9b42238f9face49145/cmake/templates/hpxrun.py.in#L249

01:43 <weilewei> Otherwise, currently, I am manually replace mpiexe as jsrun in /bin/hpxrun.py

01:51 <hkaiser> weilewei: hpx picks up some environment variables itself

01:51 <weilewei> hkaiser so will it pickup jsrun?

01:52 <hkaiser> I don't know what env variables are set by jsrun

01:52 <hkaiser> you might want to jsrun a small script that prints the environemnt

01:52 <weilewei> Oh, ok, but I think on summit, hpx script picks up mpiexe, not None

01:53 <hkaiser> no idea what you're talking about

01:54 <weilewei> sorry, let me rephrase, I would like to have a run_jsrun similar to run_mpi in https://github.com/STEllAR-GROUP/hpx/blob/c36107e13c47ff6a4ea91c9b42238f9face49145/cmake/templates/hpxrun.py.in#L71

01:54 <hkaiser> hpxrun.py is a simple pythong script, feel free to modify it as needed

01:56 <weilewei> hkaiser Thanks! I will explore a bit

02:23 <weilewei> I think my question is how can HPXRUN_RUNWRAPPER has `none`, `mpi`, 'srun' three options, but how can HPXRUN_RUNWRAPPER env var knows it is using mpi or srun? And what I would like to have is that it has the 4th option for jsrun... sorry if I throw this question again... otherwise I could not let mpi tests pass on Summit where uses jsrun

02:25 <weilewei> This line is passing `mpi` to the python script, I think, https://github.com/STEllAR-GROUP/hpx/blob/c36107e13c47ff6a4ea91c9b42238f9face49145/cmake/HPX_AddTest.cmake#L114

19:32 <weilewei> So I wrote some code adding jsrun function in hpxrun.py but the script still picks up mpiexe on Summit, any suggestion? Thanks!

19:32 <weilewei> https://github.com/STEllAR-GROUP/hpx/compare/add-jsrun

19:33 <weilewei> Wondering how does it pick up srun, if the script can pick up srun automatically, so can jsrun...? I guess

19:40 <simbergm> weilewei AFAIK it doesn't pick up srun automatically

19:40 <weilewei> simbergm hmm, got it

19:40 <weilewei> So, I need to run `hpxrun.py -r jsrun` then?
