This work analyses the effects of sequential-to-parallel synchronization and inter-core
communication on multicore performance, speedup and scaling from Amdahl's law …

In a parallel computing scenario, the synchronization overhead, needed to coordinate the
execution on the parallel computing nodes, can significantly impair the overall execution …

Augmenting Amdahl's law with a corollary for multicore hardware makes it relevant to future
generations of chips with multiple processor cores. Obtaining optimal multicore performance …

In this paper, we conduct performance scaling analysis of multithreaded multicore
processors (MMPs) for parallel computing. We propose a thread-level closed-queuing …

This paper presents a fundamental law for parallel performance: it shows that parallel
performance is not only limited by sequential code (as suggested by Amdahl's law) but is …

Multicore architectures represent the future of computing since they provide cost effective
solutions to improve throughput and performance of parallel programs while keeping power …

The scalability problem is in the first place of the dozen long-term information-technology
research goals indicated by Jim Gray [2]. Chip multiprocessors (CMPs) or multicores are …

Multicore architecture has become the trend of high performance processors. While it is
generally accepted that we have entered the multicore era, concerns exist on scaling …

Synchronization is an area that exhibits rich hardware-software interactions in
multiprocessors. It was studied extensively using microbenchmarks a decade ago. However …

For over 50 years, Amdahl's Law has been the hallmark model for reasoning about
performance bounds for homogeneous parallel computing resources. As heterogeneous …
