GPU test does not seem to run in the bot

[jpata]

In the PR #31704 I tried to run a basic unit test on the GPU using "please test". However, despite saying "enable gpu" and the test running with "ENABLE_BOT_TESTS = GPU", the test log shows that CUDA was not properly initialized.

I had the same error locally before updating the nvidia driver to the latest 455 version - possibly it's the same problem on the test infrastructure, but I was not able to check.

===== Test "test_calo_rechit" ====
Failed to initialise the CUDA runtime, the test will be skipped.

@jpata , for GPU enabled tested, bot runs two tests

• Normal PR validation tests
• GPU based tests

For #31704 bot ran the normal tests but due to a typo in bot did not start the GPU based test. Anyway, this is fixed and there is pending job in jenkins for GPU tests https://cmssdt.cern.ch/jenkins/job/ib-run-pr-tests/ . Whenever we get hold to a HTCondor GPU resources then the test will start

Thanks @smuzaffar for the clarification. So in principle the procedure we followed in #31704 should work to also successfully run the CUDA-based tests that run when doing scram b runtests?

[smuzaffar]

bot currently only running GPU based relvals for PRs, In future I will also enable running of unit tests too

Can this issue be closed?

[jpata]

yes, seems so, thanks.
