This unusual configuration is important, says Professor Erik Maehle, the director of the Institute, because there is still plenty of work to be done examining clusters. We are convinced that I/O problems in cluster computing still require considerable research, he says.
Researchers at Luebeck are using the cluster to test applications built around the Message Passing Interface (MPI) standard, a method for transferring data between processors in a cluster. The cluster is also used to support Luebecks research into biomedical applications, and it is used for student course on parallel programming, Sobe says.
Sobe says the Terragrid software did not replace a product from another vendor. Though he was unwilling to tell NDCF the value of Terrascales deal with Luebeck, he cites cost savings and better productivity as potential benefits for the University. The Institute has not quantified any specific savings, he adds.
Magellan is only one part of Luebecks cluster story. The University also runs three separate Linux-based PC clusters, containing a total of 64 PCs and 122 Intel Corp. (Nasdaq: INTC) Pentium processors. Like Magellan, the PC clusters use Linux. Their networking connectivity is Gigabit Ethernet and Myrinet.
Although he would not divulge too many specific details, Sobe confirmed that there are plans to combine the blade and PC clusters for research into network computing.
