Improving communication latency with the write-only architecture

This paper introduces a novel execution paradigm called the Write-Only Architecture (WOA) that reduces communication latency overheads by up to a factor of five over previous methods. The WOA writes data through distributed control flow logic rather than using a read–write paradigm or a centralised message hub which allows tasks to be partitioned at a fine-grained level without suffering from excessive communication overheads on distributed systems. In this paper we provide formal assignment results for software benchmarks partitioned using the WOA and previous execution paradigms for distributed heterogeneous architectures along with bounds and complexity information to demonstrate the robust performance improvements possible with the WOA.

► A general execution paradigm suitable for use in Distributed and HPC computation.
► Analysis showing up to five times lower latencies than previous paradigms.
► A formal timing model based on the new paradigm for use in objective optimisation.
► Results showing accelerations of up to 3.2 times where previous paradigms fail.
► Relative performance guarantees for the paradigm along with formal complexity analysis.
