New Features
Added

  • Eigensolver routines for symmetric/hermitian matrices:
    STERF, STEQR
  • Linear solvers for general non-square systems:
    GELS (API added with batched and strided_batched versions. Only the overdetermined non-transpose case is implemented in this release. Other cases will return rocblas_status_not_implemented status for now.)
  • Extended test coverage for functions returning info
  • Changelog file
  • Tridiagonalization routines for symmetric and hermitian matrices:
    LATRD
    SYTD2, SYTRD (with batched and strided_batched versions)
    HETD2, HETRD (with batched and strided_batched versions)
  • Sample code and unit test for unified memory model/Heterogeneous Memory Management (HMM)

Optimizations

  • Improved performance of LU factorization of small and mid-size matrices (n > 2048)

Changed

  • Raised minimum requirement for building rocSOLVER from source to CMake 3.8
  • Switched to use semantic versioning for the library
  • Enabled automatic reallocation of memory workspace in rocsolver clients

Removed

  • Removed -DOPTIMAL from the roc::rocsolver CMake usage requirements. This is an internal rocSOLVER definition, and does not need to be defined by library users

Fixed

  • Fixed runtime errors in debug mode caused by incorrect kernel launch bounds
  • Fixed complex unit test bug caused by incorrect zaxpy function signature
  • Eliminated a small memory transfer that was being done on the default stream
  • Fixed GESVD right singular vectors for 1x1 matrices

Known Issues

  • None
