Placement of Virtual Containers on NUMA systems: A Practical and Comprehensive Model

Baptiste Joseph Eustache Lepers

Our work addresses the problem of placement of threads, or virtual cores, onto physical cores in a multicore NUMA system. Different placements result in varying degrees of contention for shared resources, so choosing the right placement can have a large ef ...

Challenges of Memory Management on Modern NUMA Systems

Baptiste Joseph Eustache Lepers, Mohammad Dashti Rahmat Abadi

The latency of memory access times is hence non-uniform, because it depends on where the request originates and where it is destined to go. Such systems are referred to as nonuniform memory access (or NUMA). Current x86 NUMA systems are cache coherent (cal ...
