Changes:

  • Modified CommunicatorGrid to avoid blocking calls to MPI_Comm_dup. It now returns communicator pipelines. (#993)
  • Added support for Intel oneMKL and the intel-oneapi-mkl spack package. (#1073) (*)

Performance improvements:

  • Reduced the size of the matrix-matrix multiplications in the tridiagonal eigensolver to cover only the non deflated part of the eigenvectors. (#951 #967 #996 #997 #998)
  • Introduced stackless threads where appropriate. (#1037)

Bug fixes:

  • Use drop_operation_state to avoid stack overflows. (#1004)

Notes:

(*) At the time of the release the spack spec blaspp~openmp ^intel-oneapi-mkl threads=openmp doesn't build. If you rely on multithreaded BLAS we suggest to use blaspp+openmp ^intel-oneapi-mkl threads=openmp until spack/spack#42087 gets merged.
