Analyzing Performance and Usability of Broadcast-Based Inter-Core Communication (ATAC) on Manycore Architecture
Seo Jin Park · 2013
In this thesis, I analyze the performance and usability benefits of broadcast-based inter-core communication on manycore architecture. The problem of high communication cost on manycore architecture was tackled by a new architecture which allows efficient broadcasting by leveraging an on-chip optical network. I designed the new architecture and API for the new broadcasting feature and implemented them on a multicore simulator called Graphite. I also re-implemented common parallel APIs (barrier and work-stealing) which benefit from the cheap broadcasting and showed their ease of use and superior performance versus existing parallel programming libraries through conducting famous benchmarks on the Graphite simulator.
