ROCm/rocBLAS rocm-6.4.0

rocBLAS 4.4.0 for ROCm 6.4.0

on GitHub

Added

• rocTX support in rocBLAS (not available on Windows or in the static library version on Linux)
• On gfx12, all functions now support full rocblas_int dynamic range for batch_count
• --ninja build option
• Support for GPU_TARGETS cmake variable

Changed

• rocblas-test client removes the stress tests unless YAML-based testing or gtest_filter adds them
• rocblas clients OpenMP default threading is reduced to be less than the logical core count
• gemm_ex testing and timing reuses device memory
• gemm_ex timing initializes matrices on device

Optimized

• Significantly reduced workspace memory requirements for Level 1 ILP64: iamax and iamin
• Reduced workspace memory requirements for Level 1 ILP64: dot, asum, nrm2
• Improved the performance of Level 2 gemv for the problem sizes (TransA == N && m > 2*n) and (TransA == T)
• Improved the performance of Level 3 syrk and herk for the problem size (k > 500 && n < 4000)

Resolved issues

• gfx12: ger, geam, geam_ex, dgmm, trmm, symm, hemm, ILP64 gemm, and larger data support
• Added a gfortran package dependency for Azure Linux OS
• Outdated SLES OS package dependencies (cxxtools and joblib) in install.sh -d
• Code object stripping for RPM packages

Upcoming changes

• Deprecated the cmake variable AMDGPU_TARGETS. Use GPU_TARGETS instead.
