NUMA-Aware Java Heaps for Server Applications

This paper introduces a set of techniques to both measure and optimize memory access locality of Java applications running on cc-NUMA servers. These techniques work at the object level and use information gathered from embedded hardware performance monitors. They propose a new NUMA-aware Java heap layout. In addition, they propose...

Operating System Multilevel Load Balancing

This paper describes an algorithm that allows Linux to per-form multilevel load balancing in NUMA computers. The Linux scheduler implements a load balancing algorithm that uses structures called sched domains to build a hierarchy that represents the machine's topology. Although sched domains implementation allows Linux to build a multilevel hierarchy...
