An Evaluation of Parallel Computing in PC Clusters with Fast Ethernet
نویسندگان
چکیده
Currently, clusters of Personal Computers (PCs) with sharing Fast Ethernet may o er a signi cant price/performance ratio in parallel processing. This paper presents a study of the promising possibilities of parallelism in this environment, using both a classical numerical method to solve a di erential equation and an innovative algorithm to solve the statistical problem of density estimation. In addition, and to compare, some comparisons with an IBM SP2 are carried out.

Cost-Performance Evaluation of SMP Clusters
Clusters of Personal Computers have been proposed as potential replacements for expensive compute servers. One limitation in the overall performance is the interconnection network. A possible solution is to use multiple processors on each node of the PC cluster. Parallel programs can then use the fast shared memory to exchange data within a node, and access the interconnection network to commun...
متن کاملFast Barrier Synchronization on Shared Fast Ethernet
Shared LAN is presently the most widespread networking technology, due to its extremely low cost and favourable cost/performance ratio. Clusters of Personal Computers (PCs) leveraging shared 100base-T Ethernet may currently ooer the best price/performance in parallel processing. Most numerical parallel algorithms make heavy use of collective communications and especially barrier synchronization...
