Added

  • Addition of beta API rocblas_gemm_batched_ex3 and rocblas_gemm_strided_batched_ex3
  • Added input/output type f16_r/bf16_r and execution type f32_r support for Level 2 gemv_batched and gemv_strided_batched
  • Added rocblas_status_excluded_from_build to be used when calling functions which require Tensile when using rocBLAS built without Tensile
  • Added system for async kernel launches setting a failure rocblas_status based on hipPeekAtLastError discrepancy

Optimized

  • Trsm performance for small sizes m < 32 && n < 32

Deprecated

  • In a future release atomic operations will be disabled by default so results will be repeatable. Atomic operations can always be enabled or disabled using the function rocblas_set_atomics_mode. Enabling atomic operations can improve performance.

Removed

  • rocblas_gemm_ext2 API function is removed
  • in-place trmm API from Legacy BLAS is removed. It is replaced by an API that supports both in-place and out-of-place trmm
  • int8x4 support is removed. int8 support is unchanged
  • The #define STDC_WANT_IEC_60559_TYPES_EXT has been removed from rocblas-types.h. Users who want ISO/IEC TS 18661-3:2015 functionality must define STDC_WANT_IEC_60559_TYPES_EXT before including float.h, math.h, and rocblas.h
  • The default build removes device code for gfx803 architecture from the fat binary

Fixed

  • Make offset calculations for rocBLAS functions 64 bit safe. Fixes for very large leading dimension or increment potentially causing overflow:
    • Level2: gbmv, gemv, hbmv, sbmv, spmv, tbmv, tpmv, tbsv, tpsv
  • Lazy loading to support heterogeneous architecture setup and load appropriate tensile library files based on the device's architecture
  • Guard against no-op kernel launches resulting in potential hipGetLastError

Changed

  • Default verbosity of rocblas-test reduced. To see all tests set environment variable GTEST_LISTENER=PASS_LINE_IN_LOG
