General-Purpose GPU ISA 'WAVE' Unveiled
Key point
WAVE, a portable GPU ISA and toolchain that runs across various GPU architectures, has been unveiled.
Details
WAVE is a portable ISA (Instruction Set Architecture) and toolchain that unifies support for different GPU architectures such as NVIDIA (PTX), AMD (HIP), Apple (Metal), and Intel (SYCL).
Once a user writes a kernel just once, it provides backends that can translate it into Metal, PTX, HIP, and SYCL. This reduces hardware dependency and maximizes code reusability.
Key features are as follows:
- Hardware Verification: The same binary was confirmed to work correctly on Apple M4 Pro, NVIDIA T4, and AMD MI300X environments.
- PyTorch Integration: It integrates with PyTorch to guarantee identical training results across different backends.
- Open Source and Paper: Source code is provided via GitHub, and detailed technical content can be found in the arXiv paper.
