Picongpu: ADIOS plugin deactivated in the example Hemera profiles

[steindev]

I cannot use the ADIOS plugin for data output anymore. I believe this possibility was removed with #3395. If so, the documentation (https://picongpu.readthedocs.io/en/latest/usage/plugins.html) should be updated as well.

I think you are confusing two things @steindev . The native (old) ADIOS plugin still exists and uses ADIOS1. And you can use it in principle, just there may be issues with modern openPMD API-based tools. Then independently of that one, there is the openPMD plugin which can use either HDF5 or ADIOS2 backends. Before recently, it could have also used ADIOS1, and only that was disabled.

The native (old) ADIOS plugin still exists and uses ADIOS1.

But picongpu --help does not provide any --adios options anymore. But I just see that the adios/1.13.xxx module is not loaded anymore. It was thrown out of the .profile with #3393. As the native ADIOS1 plugin is still available, this module should be part of the .profile. Blame @PrometheusPi.

picongpu --help only provides options that are valid for how that particular instance was built (which depends on the system and the used .profile). Maybe the adios1 module should not have been excluded from the example .profile (I don't know the details of that decision). But regardless those files are just examples, as a user you normally take the example and modify for your needs, which can be e.g. adding that module back.

Ahh but loading both modules at the same time is not possible at hemera. They did not realize that adios and adios2 should be two separate modules :disappointed:

Offline discussion with @PrometheusPi: There is still an open support ticket with our IT. He will take care of it.

Solved with #3411, closing.
