IXPUG Annual Conference 2019

Conference Dates: September 24-27, 2019

Location: Globe of Science and Innovation at CERN (Geneva, Switzerland)


Event Description:

This IXPUG conference is focused on all aspects of adopting and employing state-of-the-art data-processing technologies and techniques for optimal application execution. This includes accelerators (e.g. FPGAs, GPUs), as well as topics related to system hardware beyond the processor (memory, interconnect, etc.), software tools, programming models, new workloads, and more — all with a focus on Intel platforms. The conference will provide an interactive experience, organised around key themes associated with high-performance computing, data analytics, artificial intelligence (machine and deep learning), cloud computing, and more. The meeting will be held at CERN, the European Laboratory for Particle Physics, in Geneva, Switzerland. The conference will feature keynote presentations, invited talks, 30-minute technical sessions, 10-to-15-minute lightning talks, and two-hour hands-on tutorials. Attendees will encounter an open forum, through which experts from academia and industry including Intel representatives will share best practices and techniques for maximizing software efficiency. We will share experience in using Intel architectures and technologies with fellow application programmers, software developers, scientists, researchers, academics, students, systems analysts, etc. The challenges surrounding application performance and scalability will be covered across all levels, including application tuning on large HPC systems.
