rocBLAS-0.10.3.0 release for ROCM 1.6.4

Changelist:

• add dgemm assembly from Tensile v3.4.0
• fix packaging install path
• integrate clang-format

rocBLAS-0.10.2.0 release for ROCM 1.6.4

Changelist:

• ported to CentOS
• updated to use Tensile v3.3.7 with v_add_i32->u32 fix and fix for M<4
• refactored code and tests for rocblas_pointer_mode

rocBLAS-0.10.1.0 release for ROCM 1.6.4

Changelist:

• add MI25 tuning for Tensile 3.3.4
• fix sgemm assembly kernels for thread safety
• correct iXamax to 1 based indexing
• refactor tests

Release for ROCM 1.6.4

NOTE: API breaking changes introduced in this release related to: rocblas_iXamax, rocblas_iXamin, complex functions, and half functions.

Changelist:

• correct API: rocblas_samax -> rocblas_isamax, rocblas_damax -> rocblas_idamax
• remove from the API functions for complex and half that have not been implemented
• update to Tensile v3.2.0. This uses sgemm assembly kernels for gfx803 and gfx900
• add rocblas_sgeam and rocblas_dgeam functions
• improve repeatability of rocblas_Xgemm performance tests
• update perf script

release for ROCM 1.6.3

NOTE: API breaking changes introduced in this release, primarily related to library NAME and SONAME.

Changelist:

• Library removed the suffix which annotated platform (i.e. now librocblas.so)
• so-name link renamed to reflect the MAJOR version number, (currently 0, changed from 1)
• Build system entirely rewritten to simplify build/install process. Convenience bash script added to automate builds on Ubuntu distro (install.sh script added to root)
• Tensile updated to v3.0.4, which includes fixes for NaN propogating on GEMM calls with beta == 0
• 2 new samples added in samples directory (gemm & strided gemm)
• haxpy implementation added
• extra unit tests added and benchmarking capabilities for axpy, dot, scal
• Improved stability of TRSM unit tests

rocBLAS-0.4.3.0 release for ROCM 1.6

Library release associated with ROCM v1.6 release.

Library tuned for Fiji family hardware.

rocBLAS-0.4.2.3 release for ROCM 1.5

Library release associated with the ROCm v1.5 platform release.

Library tuned for Fiji family hardware.

API Change: The order parameter has been removed from the gemm function. gemm functions now only support column major ordering. If you have row major matrices switch the following parameters: transa and transb, m and n, A and B, lda and ldb.

Below is the rocblas_sgemm function prototype.

rocblas_sgemm(
rocblas_handle handle,
rocblas_operation transa, rocblas_operation transb,
rocblas_int m, rocblas_int n, rocblas_int k,
const float *alpha,
const float *A, rocblas_int lda,
const float *B, rocblas_int ldb,
const float *beta,
float *C, rocblas_int ldc);

rocBLAS-0.4.2.0 release for ROCM 1.6

Library release associated with ROCM v1.6 platform release.

Library tuned for Fiji family hardware.

rocBLAS-0.4.0.2 release for ROCm 1.5

Library release associated with the ROCm v1.5 platform release

Library tuned for Fiji family hardware. At time of release, there is a known unit test failure in

• rocblas_trsm_matrix_size/trsm_gtest.trsm_gtest_float/12
• and others related to TRSM family

This has been identified as an issue in the software stack below the library, and a fix should be forthcoming. We will update release notes when the fix is available.

Preview Release

Support for: gemm, trmm, trsm, tritri, gemv, ger, amax, amin, asum, axpy, copy, dot, nrm2, scal, swap
