TACC adopts Intel oneAPI for remote visual analysis


The Texas Advanced Computing Center (TACC) at the University of Texas at Austin says it uses the Intel oneAPI rendering toolkit for remote analysis capabilities on the centre’s supercomputers, “providing visualization tools high fidelity for all calculation scales “.

TACC, which operates Frontera and Stampede2 supercomputers as well as more than a dozen HPC systems, said the adoption of oneAPI is part of an effort to advance its compute and visualization libraries, such as Galaxy. TACC said it will use oneAPI, Intel ray tracing libraries, and Intel CPU and Xe GPU hardware for science simulations for in situ visual analysis.

oneAPI is a cross-architecture programming model for processors and accelerator architectures (GPUs, FPGAs, and others) designed to simplify software development and enable accelerated compute without proprietary locking and support legacy code integration. “With oneAPI, developers can choose the best architecture for the specific problem they are trying to solve without needing to rewrite the software for the next architecture and platform,” said Intel.

The oneAPI Renderer Toolkit provides open source libraries for building visualization applications. Libraries have render kernels and middleware for Intel platforms and support Intel processors and future Xe architectures (GPUs). It includes Intel Embree, Intel Open, Image Denoise, Intel, Open Volume Kernel Library, Intel OSPRay, Intel OpenSWR, and other components and utilities.

“Flexible, unified programming and optimized performance with Intel oneAPI toolkits will enable high-fidelity interactive analysis on TACC computing platforms without having to implement device-specific routines for each system,” said TACC, who is an Intel Graphics and Visualization Institute of Xellence (Intel GVI).

ParaView by Kitware and VisIt by Intelligent Light are two applications supported by TACC and enabled by the oneAPI Render Toolkit. “These computational and visualization capabilities provide users around the world with the ability to perform high-fidelity analysis on data generated on TACC systems,” the center said, “without having to migrate to a separate machine, and this Flexibility allows TACC system designers to focus on maximizing the capabilities of the entire system without incorporating a separate analysis subsystem.

“Paul and the TACC and Kitware teams are the foundation of Intel GVI,” said Jim Jeffers, senior principal engineer and senior director of Intel Advanced Rendering and Visualization. “They are developing advanced scan codes such as Galaxy, the Visualization ToolKit, and performing large-scale testing of widely used visualization applications such as ParaView and VisIt. Of particular importance is the compute resources and support for all Intel GVIs provided by TACC.

“TACC’s expanded role as a oneAPI center of excellence will be a cornerstone for top scientists around the world to tackle climate change, sustainable energy production, pandemics and many other pressing challenges. . “
