It was a great week for compilers and computer architecture in Montreal during the cluster of conferences CC/CGO/HPCA/PPoPP, February 25 - March 1, 2023. Prof. Castrillon gave an overview of research topics for energy-efficient computing at the 1st Workshop on NetZero Carbon Computing (NetZero'23) on Saturday (25.02.). The workshop included insightful talks from experts on sustainable computing, an important line of research for the CC chair. Our highlight of the week was the presentation by Carlos Escuin in a collaborative work with Asif Khan with the title “Compression-Aware and Performance-Efficient Insertion Policies for Long-Lasting Hybrid LLCs”, on the first day of the the 29th IEEE International Symposium on High-Performance Computer Architecture (HPCA'23). Carlos talk was well visited and spawned great discussions.
