rocSOLVER 3.27.0 for ROCm 6.3.0

Added

• 64-bit APIs for existing functions:
  • LACGV_64
  • LARF_64
  • LARFG_64
  • GEQR2_64 (with batched and strided_batched versions)
  • GEQRF_64 (with batched and strided_batched versions)
  • POTF2_64 (with batched and strided_batched versions)
  • POTRF_64 (with batched and strided_batched versions)
  • POTRS_64 (with batched and strided_batched versions)
• Support added for the gfx1151, gfx1200, and gfx1201 architectures

Changed

• The rocSPARSE library is now an optional dependency at runtime. If rocSPARSE
  is not available, rocSOLVER's sparse refactorization and solvers functions
  will return rocblas_status_not_implemented.

Optimized

• Improved the performance of LARFG, LARF, and downstream functions such as GEQR2 and GEQRF on wave64 architectures
• Improved the performance of BDSQR and GESVD
• Improved the performance of STEDC and divide and conquer Eigensolvers

Resolved issues

• Fixed a memory allocation issue in SYEVJ that could cause failures on clients that manage their own memory.
• Fixed a synchronizarion issue with SYEVJ that could led to a convergence failure for large matrices.
• Fixed a convergence issue in STEIN stemming from numerical orthogonality of the initial choice of eigenvectors.
• Fixed a synchronization issue in STEIN.

Known issues

• A known issue in STEBZ can lead to errors in routines based on bisection to compute eigenvalues for symmetric/hermitian matrices (for example, SYEVX/HEEVX and SYGVX/HEGVX), as well as singular values (for example, BDSVDX and GESVDX).

rocSOLVER 3.26.2 for ROCm 6.2.4

Added

• GFX1151 Support

Fixed

• Fixed synchronization issue in STEIN.

Optimized

• Improved performance of Cholesky factorization.
• Improved performance of splitlu to extract the L and U triangular matrices from the result of sparse factorization matrix M, where M = (L - eye) + U.

Changed

• Renamed install script arguments of the form *_dir to *-path. Arguments of the form *_dir remain functional for
  backwards compatibility.
• Functions working with arrays of size n - 1 can now accept null pointers when n = 1.

Fixed

• Fixed potential accuracy degradation in SYEVJ/HEEVJ for inputs with small eigenvalues.
