rocSOLVER-3.12.0 for ROCm 4.2.0

Added

• Multi-level logging functionality
• Implementation of the Thin-SVD algorithm
• Reductions of generalized symmetric- and hermitian-definite eigenproblems:
  • SYGS2, SYGST (with batched and strided_batched versions)
  • HEGS2, HEGST (with batched and strided_batched versions)
• Symmetric and hermitian matrix eigensolvers:
  • SYEV (with batched and strided_batched versions)
  • HEEV (with batched and strided_batched versions)
• Generalized symmetric- and hermitian-definite eigensolvers:
  • SYGV (with batched and strided_batched versions)
  • HEGV (with batched and strided_batched versions)

Optimizations

Changed

• Sorting method in STERF as original quick-sort was failing for large sizes.

Removed

• Removed hcc compiler support

Fixed

• Fixed GELS overwriting B even when info != 0
• Error when calling STEQR with n=1 from batched routines
• Added roc::rocblas to the roc::rocsolver CMake usage requirements
• Added rocblas to the dependency list of the rocsolver deb and rpm packages

Known Issues

• Thin-SVD implementation is failing in some cases (in particular m=300, n=120) due to a possible bug in the gemm_batched routines of rocBLAS.

rocSOLVER-3.9.0 for ROCm 4.1.0

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
