Message Passing In Computer Clusters
Message passing is an inherent element of all computer clusters. All computer clusters, ranging from homemade Beowulfs to some of the fastest supercomputers in the world, rely on message passing to coordinate the activities of the many nodes they encompass.''Beowulf Cluster Computing With Windows'' by Thomas Lawrence Sterling 2001 MIT Press pages 7–9 Message passing in computer clusters built with commodity servers and switches is used by virtually every internet service.''Computer Organization and Design'' by David A. Patterson and John L. Hennessy 2011 page 64/ref> Recently, the use of computer clusters with more than one thousand nodes has been spreading. As the number of nodes in a cluster increases, the rapid growth in the complexity of the communication subsystem makes message passing delays over the Switched fabric, interconnect a serious performance issue in the execution of parallel programs.''Recent Advances in the Message Passing Interface'' by Yiannis Cotroni ...

Xeon
Xeon (; ) is a brand of x86 microprocessors designed, manufactured, and marketed by Intel, targeted at the non-consumer workstation, server, and embedded markets. It was introduced in June 1998. Xeon processors are based on the same architecture as regular desktop-grade CPUs, but have advanced features such as support for error correction code (ECC) memory, higher core counts, more PCI Express lanes, support for larger amounts of RAM, larger cache memory and extra provision for enterprise-grade reliability, availability and serviceability (RAS) features responsible for handling hardware exceptions through the Machine Check Architecture (MCA). They are often capable of safely continuing execution where a normal processor cannot due to these extra RAS features, depending on the type and severity of the machine-check exception (MCE). Some also support multi-socket systems with two, four, or eight sockets through use of the Ultra Path Interconnect (UPI) bus, which replaced ...

MPICH
MPICH, formerly known as MPICH2, is a freely available, portable implementation of MPI, a standard for message-passing for distributed-memory applications used in parallel computing. MPICH is Free and open source software with some public domain components that were developed by a US governmental organisation, and is available for most flavours of Unix-like OS (including Linux and Mac OS X). History MPICH development began in 1992, when a standard for message passing in parallel and distributed computing was still being discussed. MPICH tracked the development of the MPI standard as it evolved. This served dual purpose: to prove that the MPI standard could be implemented as defined, and that it could be done efficiently on all major platforms. Argonne National Laboratory and Mississippi State University jointly developed early versions (MPICH1) as public domain software. The CH part of the name was derived from "Chameleon", which was a portable parallel programming library devel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
