Gig E & InfiniBand Vie for Cluster Interconnect

Sun’s Michael Schulman and Josh Simons have written a great article on GigE and IB for MCAE applications:
“The choice of appropriate cluster interconnect depends in large part on the characteristics of the cluster applications that will be run on the system. Depending on the algorithms used in their implementation, the performance of parallel distributed applications can vary widely depending on interconnect characteristics. For applications that primarily transfer large pieces of data between communicating processes, available interconnect bandwidth is the primary concern: the faster data can be moved, the faster the application will run. However, for applications that transfer many very small pieces of data between processes, latency becomes the critical factor: the inherent delay built into the transfer process itself (the overhead of moving data through the system and across the interconnect to a receiving system) can be a limiting factor, reducing overall application performance.

About Rich
FlexRex began his life as a cartoon character I created a Sun Microsystems. As the world's first "fictional blogger," he appeared in numerous parody films that made fun of the whole work-from-home thing. Somewhere along the line, the Sun IT department adopted FlexRex as their spokesman in a half-dozen security awareness films for employees. So when I left Sun recently, I started FlexRex Communications, a Marketing company in Portland, Oregon.
