Fast Barrier Synchronization with AWGR-based Optical Switch in High-performance and Parallel Computing

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate speedup of barrier synchronization for parallel computing via wavelength parallelism of the optical switch using a k-ary tree to collect updates without incurring contention, and optical broadcast to distribute the notifications.
