This paper presents the implementation of MPICH2 over the Nemesis communication
subsystem and the evaluation of its shared-memory performance. We describe design …

Algorithms that have to process large data sets have to take into account that the cost of
memory access depends on where the data is stored. Traditional algorithm design is based …

This paper introduces a high performance communication middle layer, called PM2, for
hetero-geneous network environments. PM2 currently supports Myrinet, Ethernet, and SMP …

As we approach the next century, parallel machines are gradually and incrementally being
replaced by clusters of commodity workstations. The price of such a cluster is a fraction of …

Recently there has been an increased interest in the use of system-level virtualization using
mature solutions such as Xen, QEMU, or VMWare. These virtualization platforms are being …

Multiprocessors and high performance networks allow building CLUsters of MultiProcessors
(CLUMPs). One distinctive feature over traditional parallel computers is their hybrid memory …

We describe a generic programming model to design collective communications on SMP
clusters. The programming model utilizes shared memory for collective communications and …

Clusters are attractive for executing sequential and parallel applications. However, there is a
need to design a cluster distributed operating system to provide a Single System Image. A …

Clusters of multiprocessors (CLUMPs) have an hybrid memory model, with message
passing between nodes and shared memory inside nodes. We examine the performance of …

Many-core processors are gathering attention in the areas of embedded systems due to their
power-performance ratios. To utilize cores of a many-core processor in parallel …
