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…

Diverse heterogeneous platforms that utilize various types of resources such as general purpose processors, customized co-processors, hardware accelerators and FPGAs have been in the core of Customized Parallel Computing (CPC) group’s research interests for almost two decades. The group’s mission is to research and develop technologies that make customized…

Recently emerging applications like deep learning, ultra-high definition image/video processing or virtual reality require a vast amount of processing power in increasingly smaller devices never seen before. Heterogeneous architectures are seen as a solution to this problem by both, industry and academia since they provide a significantly better performance…

Few can deny that the choke points for many of today’s increasingly sophisticated systems continue to be hardware cost and power consumption. It’s no surprise that system performance has tapered off for a lack of “architectural vision.” One way out of this dilemma has been the introduction of heterogeneous computing.…
Today’s AI applications will touch every aspect of our lives—including transport, finance, retail, health care, smart manufacturing, education, and services industries. AI technologies will be at the forefront of digitally connected cars, smart manufacturing, and medical image recognition. The question to ask ourselves is how can we leverage the power…
Parmance and General Processor Technologies have been collaborating on C++17 Parallel STL offloading support based on HSA (Heterogeneous System Architecture) and GCC (GNU Compiler Collection). A working proof-of-concept has been now released and made available in https://github.com/parmance/par_offload. This post is a high level overview of the project.
Q&A WITH ARTERISIP’S J.P. LOISON, CORPORATE SoC APPLICATION ARCHITECT Editor’s Note: ArterisIP provides system-on-chip (SoC) interconnect IP to accelerate SoC semiconductor assembly for a wide range of applications from automobiles to mobile phones, IoT, cameras, SSD controllers, and servers for customers such as Samsung, Huawei / HiSilicon, Mobileye (Intel), Altera…
Introduction: AMD is a co-founder and member of the HSA Foundation. This article is excerpted and edited from a blog post by Vincent Hindriksen, founder of Stream HPC, a Netherlands-based software development company Last May, AMD open sourced the OpenCL driver stack for ROCm. With this they kept their promise…
HSA computing standards have progressed significantly since the HSA Foundation (HSAF) was established in 2012. Today, for instance, there are not only royalty free open specifications available but also fully operational production systems. In this Q&A, Dr. John Glossner, HSA Foundation president, provides additional insights on HSA-specific trends and issues:…

Heterogeneous multiprocessing (HMP) systems, using functionally asymmetric compute elements, such as application processors and microcontrollers integrated within the same SoCs, are now used extensively across a wide range of applications. These SoCs are used in smart, connected devices to transform the way we live – at home, in the car,…

High-performance processors typically employ techniques such as deep, multi-issue pipelines, branch prediction and out-of-order processing to maximize performance, but these do come at a cost; specifically, they impact power efficiency. If some of these tasks can be parallelized, this impact could be mitigated by partitioning them across a number of…

At this year’s Consumer Electronics Show, I walked many miles and saw countless demos. Several of these demos were memorable, but one in particular really got my mental gears turning: Microsoft’s HoloLens. HoloLens will spur many “aha” moments, leading to accelerated innovation in wearable computer vision devices, low-power 3D computer…

The Heterogeneous System Architecture (HSA) Foundation recently added two new HSA Academic Centers of Excellence – Technische Universitaet (TU) Darmstadt, and Friedrich-Alexander-University Erlangen-Nurnberg (FAU), both in Germany. As mentioned in previous HSA Connections posts, HSA is a standardized platform design that unlocks the performance and power efficiency of the parallel…

Heterogeneous systems typically consist of a CPU, GPU and other accelerator devices, all of which are integrated in a single platform with a shared high-bandwidth memory system. The special accelerators are used to obtain both power and performance benefits. While the shared memory system eliminates data copies between the CPU…
