Added

  • Packages for test and benchmark executables on all supported OSes using CPack.
  • Added Denormal number detection to the Numerical checking helper function to detect denormal/subnormal numbers in the input and the output vectors of rocBLAS level 1 and 2 functions.
  • Added Denormal number detection to the Numerical checking helper function to detect denormal/subnormal numbers in the input and the output general matrices of rocBLAS level 2 and 3 functions.
  • Added NaN initialization tests to the yaml files of Level 2 rocBLAS batched and strided-batched functions for testing purposes.
  • Added memory allocation check to avoid disk swapping during rocblas-test runs by skipping tests.

Optimizations

  • Improved performance of non-batched and batched her2 for all sizes and data types.
  • Improved performance of non-batched and batched amin for all data types using shuffle reductions.
  • Improved performance of non-batched and batched amax for all data types using shuffle reductions.
  • Improved performance of trsv for all sizes and data types.

Changed

  • Modifying gemm_ex for HBH (High-precision F16). The alpha/beta data type remains as F32 without narrowing to F16 and expanding back to F32 in the kernel. This change prevents rounding errors due to alpha/beta conversion in situations where alpha/beta are not exactly represented as an F16.
  • Modified non-batched and batched asum, nrm2 functions to use shuffle instruction based reductions.
  • For gemm, gemm_ex, gemm_ex2 internal API use rocblas_stride datatype for offset.
  • For symm, hemm, syrk, herk, dgmm, geam internal API use rocblas_stride datatype for offset.
  • AMD copyright year for all rocBLAS files.
  • For gemv (transpose-case), typecasted the 'lda'(offset) datatype to size_t during offset calculation to avoid overflow and remove duplicate template functions.

Fixed

  • For function her2 avoid overflow in offset calculation.
  • For trsm when alpha == 0 and on host, allow A to be nullptr.
  • Fixed memory access issue in trsv.
  • Fixed git pre-commit script to update only AMD copyright year.
  • Fixed dgmm, geam test functions to set correct stride values.
  • For functions ssyr2k and dsyr2k allow trans == rocblas_operation_conjugate_transpose.
  • Fixed compilation error for clients-only build.

Removed

  • Remove Navi12 (gfx1011) from fat binary.
