rocSOLVER 3.26.0 for ROCm 6.2.0

Added

• 64-bit APIs for existing functions:
  • GETF2_64 (with batched and strided_batched versions)
  • GETRF_64 (with batched and strided_batched versions)
  • GETRS_64 (with batched and strided_batched versions)
• Added gfx900 to default build targets.
• Partial eigenvalue decomposition routines for symmetric/hermitian matrices using Divide & Conquer and Bisection:
  • SYEVDX (with batched and strided_batched versions)
  • HEEVDX (with batched and strided_batched versions)
• Partial generalized symmetric/hermitian-definite eigenvalue decomposition using Divide & Conquer and Bisection:
  • SYGVDX (with batched and strided_batched versions)
  • HEGVDX (with batched and strided_batched versions)

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.
