Segfault in ELPA #3297
Comments
What happens if you run the test with a single thread? The pdbg-toolchain (single thread) passes with ELPA but the psmp-testers (two threads) do not. |
The psmp binary also crashes with a single thread and rank. Those binaries that don't segfault, produce wrong results instead. Note that I had to lower the threshold in my original PR. Either this bug is quite old or ALMO somehow assumes a block size of 32. |
It seems that this is not so much an issue with ALMO, but rather with ELPA (or our integration of it). As a workaround I've now switched regtest-almo-2/ion-pair.inp to scalapack. |
Hey, guys, can someone advise how to install ELPA, every time I try it crashes on me. |
@qmpotential Is it about the installation process or when you try to run it? What is your output? If it is unrelated, then please open a issue. |
Since #3184 the QS/regtest-almo-2/ion-pair.inp has been segfaulting:
I found that changing the OT preconditioner from
FULL_ALL
toFULL_KINETIC
mitigates the problem.Does anybody have an idea what might be going on?
