Abstract
We present a programming methodology and runtime performance case study comparing the declarative data flow coordination language S-NET
with Intel’s Concurrent Collections (CnC). As a coordination language S-NET
achieves a near-complete separation of concerns between sequential software components implemented in a separate algorithmic language and their parallel orchestration in an asynchronous data flow streaming network.
We investigate the merits of S-NET and CnC with the help of a relevant and non-trivial linear algebra problem: tiled Cholesky decomposition. We describe two alternative
S-NET implementations of tiled Cholesky factorization and compare them with two CnC implementations, one with explicit performance tuning and one without, that have previously been used to illustrate Intel CnC. Our experiments on a 48-core
machine demonstrate that S-NET manages to outperform CnCon this problem.
