[Trilinos-Users] MueLu stucks with subcommunicators

[Frey Matthias (PSI)]

Hi Jonathan

With the master branch it seems to work. :) I will test tomorrow more intensively and let you know. However, I'd like to use a normal release, thus, I might try with 12.14.1.

Thanks,
Matthias

Hi Matthias,

    Could you try MueLu from the master branch on github? Release 12.10.1 is fairly old.

Regards,
Jonathan

Hi

I use Tpetra and MueLu in a rather larger project where MueLu is used to solve Ax=b. It runs fine in 'normal' parallel execution. However, when I want to run several instances (e.g. when I use a genetic algorithm for optimization) by splitting the communicator MueLu gets stuck in the SetupHierarchy call. I checked the communicators and they are fine.

Has anyone experienced the same?

I'm using Trilinos release 12.10.1

Best,
Matthias
