Intel to Acquire Codeplay Software

June 1, 2022 | oneAPI Specification

Intel to Acquire Codeplay Software

Intel is further advancing its support of the oneAPI ecosystem through an agreement to acquire Codeplay Software, a global leader in cross-architecture, open, standards-based developer technologies. 

Codeplay is globally recognized for its expertise and leadership in SYCL, the Khronos Group’s open-standard programming model used in oneAPI, and its significant contributions to the industry ranging from open-ecosystem activities like SYCL and OpenCL™ to RISC-V, automotive software safety, and medical imaging. 

Codeplay has extensively delivered products supporting diverse hardware platforms globally, embracing the mission of bringing oneAPI to the masses.

Bolstered by the strength of Intel, Codeplay will be able to extend the delivery of SYCL solutions into cross-architecture and multi-vendor products, based on open standards and the open source ecosystems upon which they are built.

Heidelberg University Drives Heterogeneous Computing with oneMKL Open-source Interfaces

May 25, 2022 |  Intel® oneAPI Math Kernel Library, oneAPI Specification

Heidelberg U has recently enabled ROCm support for random number generation and BLAS in Intel® oneAPI Math Kernel Library (oneMKL) interfaces. This is a new and significant community contribution to the oneMKL interfaces project, part of the oneAPI industry initiative that provides SYCL-based APIs for math algorithms focused on CPUs and compute-accelerator architectures.

This work—adding into the project support for rocRAND and rocBLAS—now makes it possible to generate random numbers and perform linear algebra computations using the hipSYCL compiler to achieve near-native performance in cross-platform applications written in hipSYCL. Additionally, it makes oneMKL open-source interfaces the first oneAPI component with upstream support for other SYCL implementations apart from DPC++.

oneDNN AI Optimizations Turned Enabled by Default in TensorFlow 2

May 25, 2022 |  Intel® oneAPI Deep Neural Network Library

In the latest release of TensorFlow 2.9, performance improvements are delivered by Intel® oneAPI Deep Neural Network Library (oneDNN) enabled by Google as the default backend CPU optimization for x86 packages. This applies to all Linux x86 packages and for CPUs with neural-network-focused hardware features like AVX512_VNNI, AVX512_BF16, and AMX vector and matrix extensions found on 2nd gen Intel® Xeon® Scalable processors and newer CPUs.

These optimizations accelerate key performance-intensive operations such as convolution, matrix multiplication, and batch normalization, with up to 3 times performance improvements compared to versions without oneDNN acceleration.

Why It’s Important

While there is an emphasis today on AI accelerators like GPUs for machine learning and deep learning, CPUs remain a primary player in all stages of the AI workflow—ubiquitous across most personal devices, workstations, and data centers. These default optimizations will help enable millions of developers who already use TensorFlow to achieve productivity gains, faster time to train, and efficient utilization of compute.

Performance gains will benefit applications spanning natural language processing, image and object recognition, autonomous vehicles, fraud detection, medical diagnosis and treatment, and more.

Intel Open Sources SYCLomatic Migration Tool to Help Developers Create Heterogeneous Code

May 15, 2022 | Data Parallel C++/SYCL

Intel recently released an open-source tool to migrate code to SYCL through a project called SYCLomatic; it helps developers more easily port CUDA code to SYCL and C++ to accelerate cross-architecture programming for heterogeneous architectures. This open-source project enables community collaboration to advance adoption of the SYCL standard, a key step in freeing developers from a single-vendor proprietary ecosystem.

How the SYCLomatic Tool Works

SYCLomatic assists developers in porting CUDA code to SYCL, typically migrating 90-95% of CUDA code automatically to SYCL code. To finish the process, developers complete the rest of the coding manually and then custom tune to the desired level of performance.

According to James Reinders, Intel oneAPI evangelist, “Migrating to C++ with SYCL gives code stronger ISO C++ alignment, multivendor support to relieve vendor lock-in, and support for multiarchitecture to provide flexibility in harnessing the full power of new hardware innovations. SYCLomatic offers a valuable tool to automate much of the work, allowing developers to focus more on custom tuning than porting.”

SYCLomatic is a GitHub project. Developers are encouraged to use the tool and provide feedback and contributions to advance the tool’s evolution.

GROMACS & oneAPI Aid in Open Source Drug Discovery

May 5, 2022 | oneAPI Spec, Intel® oneAPI Tools

GROMACS, accelerated by SYCL, oneAPI, and multiarchitecture tools, has strong performance on GPUs based on Intel Xe Architecture

The recent GROMACS 2022 release was extended to multi-vendor architectures, including current and upcoming GPUs based on Intel Xe Architecture.  

The team, led by Erik Lindahl from Stockholm University & Royal Institute of Technology, ported GROMACS’ CUDA code, which only runs on Nvidia hardware, to SYCL using the Intel® DPC++ Compatibility Tool; the tool typically automates 90%-95% of the code1,2. The result: A single, portable, cross-architecture-ready code base that significantly streamlines development and provides flexibility for deployment in multiarchitecture environments.

The software’s accelerated compute was made possible by using Intel oneAPI cross-architecture tools—oneAPI DPC++/C++ Compiler, oneAPI libraries, and HPC analysis and cluster tools.

With GROMACS 2022’s full support of SYCL and oneAPI, we extended GROMACS to run on new classes of hardware. We’re already running production simulations on current Intel Xe architecture-based GPUs as well as the upcoming Intel Xe architecture-based GPU development platform Ponte Vecchio via the Intel® DevCloud. Performance results at this stage are impressive – a testament to the power of Intel hardware and software working together. Overall, these optimizations enable diversity in hardware, provide high-end performance, and drive competition and innovation so that we can do science faster, and lower costs downstream.

Soda Announces Intel oneAPI Center of Excellence to Support Scikit-learn Performance across Architectures

March 31, 2022 | Intel® Extension for SciKit-learn*

The Social Data research team (Soda) at Inria, France’s national research institute for digital science and technology, is establishing an Intel oneAPI Center of Excellence to focus on developing hardware-optimized performance boosters for scikit-learn, one of the most widely used machine learning libraries.

This scikit-learn extension will deliver more efficient machine learning by using oneAPI numba_dppy or DPC++ components. Additionally, the implementation will be packaged in an independently-managed project possibly maintained by scikit-learn core developers, Intel engineers, and other interested community members.

Heterogenous computing is inevitable. It happens when a host schedules computational tasks to different processors and accelerators like CPUs and GPUs. This partnership will make scikit-learn more performant and energy-efficient on multi-architecture systems.

The Technical University of Darmstadt (TU Darmstadt) Embedded Systems and Applications Group announces establishing an Intel oneAPI Center of Excellence (CoE). The center’s objective is to accelerate data parallel computing and simulation software used in medical and pharmaceutical research powered by oneAPI open cross-architecture programming.

Together with Intel, the university will port an accelerated version of the Autodock application to create a single code base that can be efficiently optimized and tuned for multiple hardware architecture targets. 

Additionally, TU Darmstadt is working on a next-gen parallel implementation of Autodock-GPU, which aims to speed up drug-discovery simulations by parallel execution across CPUs, GPUs, and FPGAs.

“The new oneAPI Center of Excellence is an exciting step forward for the multiarchitecture SYCL language and oneAPI,” says Joe Curley, vice president and general manager of Intel Software Products and Ecosystem division. “This collaboration with TU-Darmstadt team provides a path for medical and pharmaceutical researchers to use AutoDOCK-GPU productively on the hardware of their choice.”
