Abstract
We introduce the concept of memory efficiency of a parallel program. Memory efficiency is a measure of the amount of data replication in a parallel program. It describes how well a parallel program is equipped to exploit the available memory in (distributed memory) parallel computers, and whether a parallel program is scalable in its memory usage. We apply memory efficiency in the memory bounded speedup model as introduced by Sun and Ni. We show how the memory efficiency concept simplifies the analysis of the memory bounded speedup model.KeywordsMemory RequirementParallel ProgramData ReplicationTotal WorkloadSpeedup ModelThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
