Book synopsis

Excerpt from The Apram: The Rounds Complexity Measure and the Explicit Costs of Synchronization Our algorithm design is targeted at the apram model, defined more precisely in Sec tion 3. It assumes that each process can access each memory location in unit time. A non uniform environment arises because processes may proceed at considerably different speeds; in addition, the same process may proceed at different speeds at different times during the execution of the algorithm. We study the effects of the nonuniformity on the complexity of algorithms, aiming to design algorithms which perform well in such environments. Even if the underlying hardware is uniform and synchronous, the environment may appear nonuniform at the process level for several reasons. For example, it may appear nonuniform due to multitasking and consequent nonuniform task or process distribution, or because of interactions with external devices (e.g. Interrupts to service disk i/o). We hope that investigating the synchronization costs will further our understanding of some of the issues involved in parallel computation. The better we understand the issues involved the more likely we are to develop better abstract computational models, which will ultimately guide us in taking advantage of the power of parallelism.
