Error using Gkeyll on Arch Linux (after 30/07/2023) #147

Open Kooper95 opened 11 months ago

Kooper95 commented 11 months ago

Hello,

We recently encountered an issue with running Gkeyll on the newest version of Arch Linux. If Gkeyll is initialised using OpenMPI and more than 2 workers, then the simulation will fail. Or, if 1 to 2 workers are used on a non-uniform grid then the grid file is not written to a local file.

For those looking for a fix, we downgraded packages (all packages on our local machines) to their state at 30/07/2023 which solves the issue.

Presumably this is an error relating to "adios 1.13.1.post5" interacting with the new glibc library (2.38-1 and later). A file containing the full output is below.

Thanks @Kooper95 It's very possible that new Linux and OpenMpi versions throw errors related to ADIOS 1, since it is no longer maintained. We will likely move to ADIOS 2 in the near future.
