Analyzing performance and usability of broadcast-based inter-core communication (ATAC) on manycore architecture

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 ecient 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 benet 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.
