MIGraphX 2.5 for ROCm 5.5.0

Added

• Y-Model feature to store tuning information with the optimized model
• Added Python 3.10 bindings
• Accuracy checker tool based on ONNX Runtime
• ONNX Operators parse_split, and Trilu
• Build support for ROCm MLIR
• Added migraphx-driver flag to print optimizations in python (--python)
• Added JIT implementation of the Gather and Pad operator which results in better handling of larger tensor sizes.

Optimizations

• Improved performance of Transformer based models
• Improved performance of the Pad, Concat, Gather, and Pointwise operators
• Improved onnx/pb file loading speed
• Added general optimize pass which runs several passes such as simplify_reshapes/algebra and DCE in loop.

Fixed

• Improved parsing Tensorflow Protobuf files
• Resolved various accuracy issues with some onnx models
• Resolved a gcc-12 issue with mivisionx
• Improved support for larger sized models and batches
• Use --offload-arch instead of --cuda-gpu-arch for the HIP compiler
• Changes inside JIT to use float accumulator for large reduce ops of half type to avoid overflow.
• Changes inside JIT to temporarily use cosine to compute sine function.

Changed

• Changed version/location of 3rd party build dependencies to pick up fixes
