v2.3.0
32e1f44

Changes:

  • Increased minimum CMake version to 3.18 and adapted to use CUDA as a language, making it possible to compile with HPC SDK
  • Improved performance of compute_values_kernel by ~1.3x
  • Optimised block tuning for aggressive coarsening
  • Added an exact coarse solve, accessible via the default scope flag "exact_coarse_solve"
  • Fixed issue where latency hiding could be enabled/disabled asymmetrically across available ranks
  • Fixed bug with SpGEMM fallback that deleted cuSPARSE handle incorrectly
  • Fixed bug with use of shared memory in estimate_c_hat_kernel

Tested configurations:

  • Linux x86-64:
    -- Ubuntu 20.04, Ubuntu 18.04
    -- gcc 7.4.0, gcc 9.3.0
    -- OpenMPI 4.0.x
    -- CUDA 11.0, 11.2
  • Windows 10 x86-64:
    -- MS Visual Studio 2019 (msvc 19.28)
    -- MS MPI v10.1.2
    -- CUDA 11.0

Note that while AMGX has support for building in Windows, testing on Windows is very limited.
