HIPCL: From CUDA to OpenCL Execution

• Tags: opencl cuda

Heterogeneous-Compute Interface for Portability (HIP) is a runtime API and a conversion tool to help make CUDA programs more portable. It was originally contributed by AMD to the open source community with the intention to ease the effort of making CUDA applications also work on AMD’s ROCm platform.

While AMD and NVIDIA share the vast majority of the discrete GPU market, it is useful to make this “CUDA portability enhancement route” available to an even wider set of platforms. Since the Khronos OpenCL standard remains the most widely adopted cross-platform heterogeneous programming API/middleware, it is interesting to study whether HIP could be ported on top of it, expanding its scope potentially to all OpenCL supported devices. We in Customized Parallel Computing group, Tampere University, Finland, are happy to announce that to have worked on such a tool, known as HIPCL, for some time and it’s now published and available in Github.

The first release of HIPCL is a proof-of-concept, but is already useful for end-users. It can run most of the CUDA examples in the HIP repository and the list of supported CUDA applications will grow steadily as we add new features.

Hardware accelerators are power efficient implementations of challenging algorithms in heterogeneous computing platforms which are used to make key tasks in applications such as video codecs or machine vision pipelines faster, more power efficient, and less chip area consuming. Fixed function hardware accelerators are the latest class of devices Portable Computing Language (<a href=“http://portablecl.org”>POCL</a>) adds to its diverse palette of supported device types in the same OpenCL context.

Real-time interactive simulations of large-scale heart arrhythmias using WebGL

• Tags: webgl

/assets/uploads/news/news_graphics/F4.large_.jpg

In a recent article of Science Advances, we introduced a WebGL library Abubu.js that makes easier to program and create high-performance simulation of cardiac dynamics and other large-scale systems like fluid flow and crystal growth. Making these kind of simulations and studies accessible to virtually anyone with a modest computer. For cardiac dynamics, this approach will allow not only scientists and students but also physicians to use physiologically accurate modeling and simulation tools that are interactive in real time, thereby making diagnostics, research, and education available to a broader audience and pushing the boundaries of cardiac science.
