document: The MAGNeT toolkit : design , implementation and evaluation The current trend in constructing high-performance computing systems is to connect a large number of machines via a fast interconnect or a large-scale network such as the Internet . This approach relies on the performance of the interconnect -LRB- or Internet -RRB- to enable fast , large-scale distributed computing . A detailed understanding of the communication traffic is required in order to optimize the operation of the entire system . Network researchers traditionally monitor traffic in the network to gain the insight necessary to optimize network operations . Recent work suggests additional insight can be obtained by also monitoring traffic at the application level . The Monitor for Application-Generated Network Traffic toolkit -LRB- MAGNeT -RRB- we describe here monitors application traffic patterns in production systems , thus enabling more highly optimized networks and interconnects for the next generation of high-performance computing systems
