Guillaume Mercier defended his habilitation on December 4th. His habilitation is entitled “Challenges of Message Passing Evolution and Management of Hierarchical Hardware Topologies”.
Cartesian Collective Communication “Advice to users”, “Advice to implementers”, and “Advice to Standardizers” Cartesian Collective Communication (or stencil communication) is a restricted form of general, sparse, graph neighborhood collective communication as known in for instance MPI. The prime charactistic of Cartesian Collective Communication is that processes organized in a d-dimensional torus (or mesh) all communicate …
Brice will present his article published at Cluster 2018 with ENS Lyon, UTK and Georgiatech. Title: Co-scheduling HPC workloads on cache-partitioned CMP platforms Co-scheduling techniques are used to improve the throughput of applications on chip multiprocessors (CMP), but sharing resources often generates critical interferences. We focus on the interferences in the last level of cache …
Emmanuel Jeannot will present us an empirical study he achieved in the domain of process affinity. Title : Process Affinity, Metrics and Impact on Performance: an Empirical Study Abstract: Process placement, also called topology mapping, is a well-known strategy to improve parallel program execution by reducing the communication cost between processes. It requires two inputs: …
