Chiola, G.; Ciaccio, G. Implementing a low cost, low latency parallel platform. (English) Zbl 0904.68005 Parallel Comput. 22, No. 13, 1703-1717 (1997). Summary: The cost of high-performance parallel platforms prevents parallel processing techniques from spreading in present applications. Networks of Workstations (NOW) exploiting off-the-shelf communication hardware, high-end PCs and standard communication software provide much cheaper but poorly performing parallel platforms. In our NOW prototype called GAMMA (Genoa Active Message MAchine) every node is a PC running a Linux operating system kernel enhanced with efficient communication mechanisms based on the Active Message paradigm. Active Messages supply virtualization of the network interface close enough to the raw hardware to guarantee good performance. The preliminary performance measures obtained by GAMMA show how competitive such a cheap NOW is.
