Profile-Guided Proactive Garbage Collection for Locality Optimization

Many applications written in garbage collected languages have large dynamic working sets and poor data locality. This paper presents a new system for continuously improving program data locality at run time with low overhead. The key contributions include making a case that garbage collection should be viewed as a proactive...

Cache Optimization for Coarse Grain Task Parallel Processing Using Inter-Array Padding

The wide use of multiprocessor system has been making automatic parallelizing compilers more important. To improve the performance of multiprocessor system more by compiler, multigrain parallelization is important. In multigrain parallelization, coarse grain task parallelism among loops and subroutines and near fine grain parallelism among statements is used in addition...

Optimization of Frequent Itemset Mining on Multiple-Core Processor

Multi-core processors are proliferated across different domains in recent years. This paper studies the performance of frequent pattern mining on a modern multi-core machine. A detailed study shows that, even with the best implementation, current FP-tree based algorithms still under-utilize a multi-core system due to poor data locality and insufficient...

Accelerating Security Applications With Intel Multi-Core Processors

The transition to multi-core processors offers flexibility for development and optimization of higher performance applications. Multi-core architectures can significantly improve program flow so that cache memory associated with each execution core is used more effectively. With multiple caches, optimizing data locality is possible, driving higher cache-hit rates and improved overall...

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...
