Hip: C++ Heterogeneous-Compute Interface for Portability

Summary

What is this repository for? HIP is a C++ Runtime API and Kernel Language that allows developers to create portable applications for AMD and NVIDIA GPUs from single source code. Key features include: HIP is very thin and has little or no performance impact over coding directly in CUDA mode. HIP allows coding in a single-source C++ programming language including features such as templates, C++11 lambdas, classes, namespaces, and more. HIP allows developers to use the "best" development environment and tools on each target platform. The HIPIFY tools automatically convert source from CUDA to HIP. Developers can specialize for the platform (CUDA or AMD) to tune for performance or handle tricky cases. New projects can be developed directly in the portable HIP C++ language and can run on either NVIDIA or AMD platforms. Additionally, HIP provides porting tools which make it easy to port existing CUDA codes to the HIP layer, with no loss of performance as compared to the original CUDA application. HIP is not intended to be a drop-in replacement for CUDA, and developers should expect to do some manual coding and performance tuning work to complete the port. Note The published documentation is available at HIP documentation in an organized, easy-to-read format, with search and a table of contents. The documentation source files reside in the HIP/docs folder of this GitHub repository. As with all ROCm projects, the documentation is open source.
