Indeed, the cost of a cluster can be very high, since enterprises have to deal with acquisition costs, as well as...
This paper introduces Madeleine II, an adaptive and portable multiprotocol communication library for high-performance multithreaded applications. Madeleine II has the ability to control multiple network protocols (BIP, SISCI, VIA) and multiple network adapters (ethernet, myrinet, SCI). Moreover, it includes advanced mechanisms to dynamically select the most appropriate transfer method for a given...
