Performant and Available Computing Systems Lab
Welcome to the homepage of the Performant and Available Computing Systems (PACS) Lab at York University, led by Dr. Hamzeh Khazaei. We analyze, model, design, and build large-scale computing systems focused on performance and availability. The PACS Lab is part of the Electrical Engineering and Computer Science Department within the Lassonde School of Engineering, located in the vibrant, multicultural city of Toronto.
We are excited to welcome new members at all academic stages. To join, please visit our Join Us! page for all the details you need to get started.
