Changelog

v0.3.7 (2023-12-22)

  • New Features

    • Enabled multi-SKUs support.
    • Refined the project’s coding conventions.
    • Cleaned up building warnings.
    • Upgraded the toolchain to oneAPI-2024.0.0
    • Updated documents, tests, and examples.

  • Known Issues

v0.3.6 (2023-11-10)

  • New Features

    • Added GEMM new feature for any shapes support (odd shapes).
    • Provided default configurations for GEMM API (users could get good performance by default configurations, only advanced users need to tune optimization options).
    • Supported converting register layout between tiled and linear.
    • Provided flexible large shape's APIs for other policy (e.g. splitk, improved mat_A & mat_B cache hit ratio).
    • Refined mem_desc_t and payload_t to expose alignment parameter.
    • Enabled epilogue to support D = alpha * A * B + beta * C.
    • Replaced xetla_exec_item with sycl::nd_item.
    • Refined some examples to invoke kernel level APIs, added fence and barrier to MLP example.
    • Fixed some known issues, enhanced tests, and updated documents.

  • Known Issues

v0.3.5 (2023-09-28)

  • New Features

    • Enhanced limitation checking.
    • Refined GEMM APIs’ name.
    • Supported GEMM APIs load B from SLM.
    • Supported GEMM of any (odd) shapes.
    • Supported Streaming-K.
    • Enhanced L3 K-slicing support.
    • Improved GEMM's performance for large-N (M, N, K) shapes.
    • Fixed tile load/store bugs.
    • Enhanced examples, tests, and updated documents.

  • Known Issues

v0.3.4 (2023-08-18)

  • New Features

    • Enabled limitation checking.
    • Provided "XETLA_PRINTF" and "XETLA_ASSERT" for debugging.
    • Refined fpu based GEMM.
    • Refined tile reduce APIs, deprecated API "tile_row_reduce".
    • Supported new data type int4 (experimental feature).
    • Fixed tile load/store bugs.
    • Enhanced examples, tests, and updated documents.

  • Known Issues

v0.3.3 (2023-06-30)

  • New Features

    • Enabled debug build support.
    • Updated documents, added some diagrams and details.
    • Fixed some customer reported issues.
    • Improved the project's quality.

  • Known Issues

v0.3.2 (2023-06-16)

  • New Features

    • Added some kernel-level APIs' parameters check functions, users need to explicit call them before launch the kernel; will return fail and print error messages when detect unsupported scenarios, continue launching the kernel for unspported scenarios may lead to unpredictable result.
    • Removed reduce_sum + tile_op epilogue policy.
    • Added some unit test cases.
    • Refined some examples code.
    • Updated documents, added some diagrams and details.
    • Fixed some customer reported issues.
    • Improved the project's quality.

  • Known Issues

v0.3.1 (2023-05-22)

  • New Features

    • Initial open source release.
    • Improved subgroup level fundamental features: core, tile, utils.
    • Enhanced basic BRGEMM micro-kernels for different data types as well as different epilogue flavours.
    • Unified the examples: basic BRGEMM, GEMM; fusion BRGEMM, GEMM; batched GEMM; MLP, GRU, MHA.
    • Added some unit test cases.

  • Known Issues

v0.3.0 (2023-04-23)

  • New Features

    • Initial internal release.
    • Subgroup level fundamental features: core, tile, utils.
    • Basic BRGEMM micro-kernels for different data types as well as different epilogue flavours.
    • Examples
      • Basic BRGEMM, GEMM; fusion BRGEMM, GEMM; batched GEMM; MLP, GRU, MHA.
