Performance evaluation of applications running on a Grid is a challenging task. Grid's resources are heterogeneous in nature, often shared, and dynamic, all of which have imp...

In this paper we present an automated way of using spare CPU resources within a shared memory multi-processor or multi-core machine. Our approach is (i) to profile the execution o...
We introduce a new performance metric, called Load Balancing Factor (LBF), to assist programmers with evaluating different tuning alternatives. The LBF metric differs from traditi...
