ScaLAPACK¶
About¶
ScaLAPACK is a doc:lapack replacement/enhancement that runs on parallel distributed memory machines (using MPI).
Supported versions¶
To check which ScaLAPACK versions and build types are currently supported on Discoverer, execute on the login node:
module avail scalapack
The recipe used for compiling the programming code of ScaLAPACK on Discoverer is publicly available at:
https://gitlab.discoverer.bg/vkolev/recipes/-/tree/main/scalapack
Warning
Intel oneAPI comes with its own ScaLAPACK library, which is included in MKL. We do not recommend the use of that ScaLAPACK library installation. There is a general problem with using Intel MPI library on Discoverer compute nodes, which affects the MPI-based MKL subroutines.
Loading/Compiler affinity¶
