ICLDisco / dplasma

DPLASMA is a highly optimized, accelerator-aware, implementation of a dense linear algebra package for distributed heterogeneous systems. It is designed to deliver sustained performance for distributed systems where each node featuring multiple sockets of multicore processors, and if available, accelerators, using the PaRSEC runtime as a backend.

getrf_1d result suspicious on Guyot #115

Open abouteiller opened 5 months ago

abouteiller commented 5 months ago

Describe the bug

Result is suspicious when running ctest dgetrf_1d_mpi, the failure is deterministic, but happens only on the Guyot system (w/o GPU). Same setup will never fail on Leconte. Using variants of gcc/11,12,13; using openblas vs mkl, causes the same errors in the same cases.
