`setup-matlab@v2`: issues with Parallel Computing Toolbox #94

Closed zaikunzhang closed 6 months ago

zaikunzhang commented 7 months ago

Hi @mcafaro ,

How does the built-in cache of setup-matlab@v2 distinguish different caches? Does it respect the with, especially release and products? As far as I have observed, it does not respect products. This seems to be a bug.

Thank you for taking a look.

Best regards, Zaikun

It caches MATLAB by platform, architecture, release and products. Yes, it should respect the release and products provided in with. If you add or remove a product from the products list, we have to recreate the cache from scratch.

Please also remember that the GitHub cache is limited to 10 GB and 7 days.

OK. My observation was wrong. Now I see the real problem: in previous versions, setup-matlab installs "Parallel Computing Toolbox" by default (I cannot find the documentation anymore, but I remember reading it somewhere). But this is not the case in the latest version. Am I right? Thanks.

mcafaro commented 7 months ago

That is right. v2-beta required Parallel Computing Toolbox, so it would install it by default. v2 no longer has that requirement. v2 only installs MATLAB by default.

I added "Parallel_Computing_Toolbox" to the products. It was installed, but did not work.

I find that all parfor loops receive the following message: 

2024-02-13T03:14:27.9851980Z Starting parallel pool (parpool) using the 'Processes' profile ...
2024-02-13T03:14:41.0675949Z Parallel pool using the 'Processes' profile is shutting down.

Nothing happens between these two lines. Is this expected or a bug?

mcafaro commented 7 months ago

There is a known issue with parpool at the moment. We are working on it.

Hi @zaikunzhang ,

The issues with Parallel Computing Toolbox should now be resolved. Please let us know if you continue to see them.

Thanks, David
