Speakers:

Stephen Blair-Chappell is an independent software consultant and is an Intel-certified oneAPI instructor. He was formerly the Technical Director at Bayncore where he led a team of consultants providing HPC and AI training on Intel Architecture. For 18 years he was a Technical Consulting Engineer at Intel helping their strategic customers in software optimization and code modernization. He is the author of the book "Parallel Programming with Intel Parallel Studio XE".

Biagio Cosenza is a tenure-track Assistant Professor in the Department of Computer Science at the University of Salerno, Italy, and a member of the Khronos SYCL Working Group. He joined the University of Salerno in August 2019 through a national brain gain program (Attraction and International Mobility), and received the Abilitazione for Italian Associate Professorship. From 2015 to 2019, he was Senior Research at the TU Berlin, Germany, where he was Principal Investigator for the DFG project Celerity and received the Habilitation from the Faculty IV. From 2011 to 2015, he was Postdoctoral researcher at the University of Innsbruck, Austria, where he contributed to the Insieme Compiler project and the DK- Plus multidisciplinary platform for Scientific Computing. His research is currently funded by the European HPC Joint Undertaking (LIGATE project), the Italian Ministry of Research (LibreRT project, PRIN 2022), and several industrial projects. Cosenza’s main research interests are in the field of high performance computing, in particular with respect to programming models, compiler technology, optimization and tuning.
