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.
