Just Announced! oneAPI Bring-Your-Own-Code (BYOC) Workshop

Have a code that will benefit from heterogenous hardware? In this workshop on Monday, October 19th 8:00AM-12:00PM PT (10:00AM-2:00PM CT) you will have an opportunity to work directly with oneAPI experts to make the code heterogenous. Register via Webex HERE. Participants present their workload and instructors answer questions. Each team gets half an hour and follow up sessions scheduled individually as needed based on topics below: 

DPC++ essentials – Praveen Kundurthy and Rakshit Krishnappa
DPCT – Sunny Gogar and Edward Mascarenhas
DPC++ GPGPU – Ruyman Reyes
Advisor – Vladimir Tsymbal and Prof Aleksandar Ilic
FPGA – Ricardo Menotti
AI/oneDAL/XGBoost – Louie Tsai, Rachael Oberman

We will consider BYOC workshop successful if we are able to help you in porting and tuning of the participants’ codes, either during the workshop or up to two weeks after the workshop.


Call for Presentations:

This Intel eXtreme Performance User Group (IXPUG) conference is focused on all aspects of adopting and employing state-of-the-art technologies and practices for optimal application execution. This includes accelerators (e.g., co-processors, FPGAs, GPUs), as well as topics related to system hardware beyond the processor (memory, interconnects, etc.), software tools, programming models, HPC workloads, troubleshooting, and more — all with a focus on Intel platforms. The conference will provide an interactive experience, organized around key themes associated with high-performance computing, data analytics, artificial intelligence (machine learning and deep learning), cloud computing, and more. The conference will feature keynote presentations, invited expert talks, 30-minute technical sessions, 10-to-15-minute lightning talks, and two-hour hands-on tutorials. Speakers come from a wide variety of HPC organizations and share their real-world experiences. Attendees will encounter an open forum, through which Intel and renowned industry experts will share best practices and techniques for maximizing software productivity and efficiency. The conference will provide an opportunity to share experiences in leveraging Intel architectures and technologies with all attendees, including expert software developers, scientists, researchers, academics, systems analysts, students, and end-users, etc. The challenges surrounding application performance and scalability will be covered across at all levels, including tuning and optimization of diverse sets of applications on large-scale HPC systems.
