Large scale Grid applications are often composed a distributed collection of parallel simulation codes, instrument monitors, data miners, rendering and visualization tools. For example, consider a severe storm prediction system driven by a grid of weather sensors. Typically these applications are very complex to build, so users interact with them through a Grid portal front end. This talk outlines...
Superscalar processors tolerate long-latency memory operations by maintaining a high number of in-flight instructions. Since the gap between processor and memory speed continues increasing every year, the number of in-flight instructions needed to support the large memory access latencies expected in the future should be higher and higher. However, scaling-up the structures required by current processors...
Distributed parallel execution systems speed up applications by splitting tasks into processes whose execution is assigned to different receiving nodes in a high-bandwidth network. On the distributing side, a fundamental problem is grouping and scheduling such tasks such that each one involves sufficient computational cost when compared to the task creation and communication costs and other such practical...
Simple parallel programming frameworks such as Pthreads, or the six function core of MPI, are universal in the sense that they support the expression of arbitrarily complex patterns of computation and interaction between concurrent activities. Pragmatically, their descriptive power is constrained only by the programmer’s creativity and capacity for attention to detail. Meanwhile, as our understanding...
