Pull request overview
This PR extends the CoralGemm GPU benchmark test to support BF16 (brain floating point 16-bit) precision in addition to the existing FP32 and FP64 support. BF16 is a reduced-precision format commonly used in AI/ML workloads to achieve higher throughput while maintaining sufficient numerical accuracy.
Key changes:
- Added 'R_16B' (BF16) to the supported precision types
- Configured BF16 to use FP32 for output matrix and computation precision (mixed-precision GEMM)
- Added performance reference values for BF16 across three GPU architectures (mi200, mi300, gh200)
