- Install a driver and toolkit appropriate for your system (SDK is not necessary)

NVIDIA reports that cuSOLVERMp 0.4.2 through 0.8.0 contain an STEDC defect
affecting non-power-of-two block sizes and certain 2D process grids. Because
`Syevd` and `Sygvd` use STEDC internally, affected versions may fail or hang
during distributed diagonalization. ABACUS therefore requires cuSOLVERMp 0.9.0
or newer when `ENABLE_CUSOLVERMP=ON`. The recommended stack is cuSOLVERMp 0.9.0
with cuBLASMp 0.9.1. See the
[cuSOLVERMp 0.9.0 release notes](https://docs.nvidia.com/cuda/cusolvermp/release_notes/index.html#cusolvermp-v0-9-0)
for the upstream fix details.
