    This is unmodified Arkouda
    I'm also using the chapel module on Swan (Cray-XC)
    I filed an issue for this: Bears-R-Us/arkouda#955
    I think you are fine to comment out the failed assertion here until we fix it since the types are actually correct, just fully qualified versus the short name versions.

    We will NOT be having the Arkouda Weekly Call today because of a conflicting meeting.

    Another error, this time in tests/categorical_test.py::CategoricalTest::testSaveAndLoadCategorical
    Does h5ls exist on the machine you're running the test on? i.e. which h5ls ?
    Louis Jenkins
    :o I don't have that
    Oh wait
    I didn't have module loaded
    Shall I try it again?
    For clarity: I am running on both a Cray-XC and an older infiniband machine
    I would expect it to work as long as h5ls is installed and accessible
    Also because it's relevant I was considering taking on this ticket Bears-R-Us/arkouda#452 which would remove the need for h5ls installation
    Louis Jenkins
    Cool, it worked!

    It is unfortunate that the client does not have a way of backing out when the server is unavailable in between tests. It seems to happen at random times, but client is just hanging.
    If you are running the unit tests on a multi-locale system the hangling client is generally indicative of the server dying for some reason. How many locales are you running on? (There are a few known issues with running unit tests with small amounts of data on systems with num_locales > num_data_elements and I'm wondering if that's what you're running into.
    I'd also advocate for running a specific test file / class with the -v flag on first to get an idea of what test is failing, then running it with the -s flag to capture the output.
    python3 -m pytest tests/categorical_test.py::CategoricalTest -v
    Louis Jenkins
    The default number of locales which is 2
    I'll try the -s flag

    It works fine down to testEquality

    This one is on a Cray-XC

    Are you pip installing from pypi or are you building your own client package to install (https://github.com/Bears-R-Us/arkouda#install-ak).

    You shouldn't install from pypi as we have not updated that in quite some time and it will not work with the current server.

    :o I see, I got it now, thanks

    hi all - new to this project. i have just been playing with arkouda for the past month or so.

    i am having an issue with using a system where 256 threads are available (2 x 64 core processors with hyperthreading) and am only getting 128ish arkouda threads. how is the number of arkouda threads spun up decided for a given system? it seems there is a default value that applies to smaller machines but not this machine i am trying. Is there a max number of threads? Is there a flag to specify how many threads to spin up when starting the server? Thanks!

    Elliot Ronaghan
    Arkouda is backed by Chapel, and by default Chapel uses physical cores only and not hyperthreads (which generally do not help performance of HPC Applications). You can control this value manually with CHPL_RT_NUM_THREADS_PER_LOCALE, but generally speaking using logical threads will not help performance and may in fact hurt. See https://chapel-lang.org/docs/usingchapel/tasks.html#controlling-the-number-of-threads for more info.

    Thanks Elliot! that’s helpful

    @mhmerrill Hey Mike! Hope all is well. Where do we find the link with the weekly Arkouda meeting presentations on GitHub? I want to reference a student to one of the first ones you gave, but I am having trouble finding it on GitHub, thanks!
    I found it
    Hi All, Mike asked me to pass on the following message:
    ATTENTION: We will NOT be having the Arkouda Weekly Call today.
    He expects things to resume as normal next week. Thanks!
    Louis Jenkins
    I think I found reason why it was hanging during those tests from before; the walltime is set to a default 300 seconds; is there a way to specify the test use a walltime for each test?
    Louis Jenkins
    Also interestingly enough, the memory limit does not seem to increase per-locale Nevermind

    I'm fairly certain the reason for hanging/failure was the server process dying and the client ZMQ socket waiting for reconnection. If that's the case the test will never actually complete and should be considered failed as soon as the server process dies.

    However, if you want to try to increase the time out you can install the pytest-timeout plugin and it enables the cmd line arg --timeout=300 where the value is in seconds. An alternative is to try and use pytest marks to set something on a specific test @pytest.mark.timeout(10, "slow", method-"thread") (from the pytest docs)

    Does anyone have a subject they would like to discuss at today's Arkouda weekly call?
    Michael Merrill
    Sorry for the late notice but since we don't have a topic... ATTENTION: We will NOT be having the Arkouda Weekly Call today.
    kay doh
    @glitch can you let me know if you are online?
    Michael Merrill
    Good Morning! We will NOT be having an Arkouda Weekly Call today.
    We will resume next Tuesday at 1pm!
    I just got a chapel 1.25.0 built and (I think) running on my cluster with gasnet (ibv conduit) to try with arkouda. For getting the arkouda part, should I clone master and follow the instructions? Or is there a release someplace that I missed?

    @dgrichardson : I think in practice most Arkouda devs and power users clone master for Arkouda. And I believe it’s currently in a clean state based on recent nightly testing runs.
    Thanks. I'll clone master.
