An OpenMP backend for the Σc streaming language

Conference of International Conference on Computational Science ICCS 2017 ; Conference Date: 12 June 2017 Through 14 June 2017; Conference Code:136818International audienceThe ΣC (pronounced "Sigma-C") language is a general purpose data-flow language that was initially targeted for Kalray's MPPA embedded many-core processor. It is designed as an extension of C, allowing the Cyclo-Static Data-Flow (CSDF) model of computation. Until now, it was only available for the first generation of the MPPA chip. In this paper, we show how we built an OpenMP back-end for the ΣC language, and we used this compiler to evaluate some of the assets of stream programming and some limitations of the current implementation, by evaluating the performance on several benchmark programs. This new back-end could open the way to utilize this language to study embedded stream programming concepts or to program HPC applications
