| - | The concept of "Beowulf" clusters, or cheap clusters formed by a network of workstations, increased dramatically the performance-over-price ratio in the high performance computing world. Nevertheless, many domain scientists and engineers using such clusters, have realized that the performance they can actually harness is only a fraction of what is available. Two reasons are mainly responsible for this effect. First, the level of complexity required for the communication of an application to be optimized for a particular cluster makes such optimizations out of reach for most non-expert systems programmers. At the same time the lack of portability experienced by applications tuned for specific cluster, led most domain scientists and engineers to follow high-level generic communication solutions in their applications. In this project we are trying to use compiler technology to automatically fine tune applications while preserving the simplicity experienced by the programmer. | + | The concept of "Beowulf" clusters, or cheap clusters formed by a network of workstations, increased dramatically the performance-over-price ratio in the high performance computing world.
