rocBLAS 2.41.0 for ROCm 4.5.0

Optimizations

• Improved performance of non-batched and batched syr for all sizes and data types
• Improved performance of non-batched and batched hemv for all sizes and data types
• Improved performance of non-batched and batched symv for all sizes and data types
• Improved memory utilization in rocblas-bench, rocblas-test gemm functions, increasing possible runtime sizes.
• Improved performance of non-batched and batched dot, dotc, and dot_ex for small n. e.g. sdot n <= 31000.
• Improved performance of non-batched and batched trmv for all sizes and matrix types.
• Improved performance of non-batched and batched gemv transpose case for all sizes and datatypes.
• Improved performance of sger and dger for all sizes, in particular the larger dger sizes.
• Improved performance of syrkx for for large size including those in rocBLAS Issue #1184.

Changed

• Update from C++14 to C++17.
• Packaging split into a runtime package (called rocblas) and a development package (called rocblas-dev for .deb packages, and rocblas-devel for .rpm packages). The development package depends on runtime. The runtime package suggests the development package for all supported OSes except CentOS 7 to aid in the transition. The suggests feature in packaging is introduced as a deprecated feature and will be removed in a future rocm release.

Fixed

• For function geam avoid overflow in offset calculation.
• For function syr avoid overflow in offset calculation.
• For function gemv (Transpose-case) avoid overflow in offset calculation.
• For functions ssyrk and dsyrk, allow conjugate-transpose case to match legacy BLAS. Behavior is the same as the transpose case.
