Heterogeneous Distributed Computing
One of the biggest challenges with high-performance computing is that as machine architectures become more advanced to obtain increased peak performance, only a small fraction of this performance is achieved on many real application sets. This is because a typical application may have various subtasks with different architectural requirements. When such an application is executed on a given machine, the machine spends most of its time executing subtasks for which they are unsuited. With the recent advances in high-speed digital communications, it has become possible to use collections of different high-performance machines in concert to solve computationally intensive application tasks. This paper describes the issues involved with using such a Heterogeneous Computing (HC) suite of machines to solve application tasks.
