At runtime, sections of the SIMD array can be reconfigured as additional CPU cores, interconnected via a message ring. Effective use is made difficult by the low-level message passing API and lack of cache coherency between processors. The AutoPilot library addresses this by providing a high-level message-oriented parallel programming model mirroring that of Pilot, itself a wrapper around the Message Passing Interface (MPI) for cluster computing. AutoPilot shows that Pilot's processes-and-channels architecture is a viable choice for parallel programming on cache-incoherent multicore and manycore architectures. It provides a simpler API for programmers, with built-in safety checks that eliminate some common sources of errors. Since the IMAPCAR2 is targeted chiefly at automotive applications, open source AutoPilot has a large degree of MISRA-C compliance.","PeriodicalId":84860,"journal":{"name":"Histoire & mesure","volume":"24 1","pages":"62-65"},"PeriodicalIF":0.0,"publicationDate":"2013-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78812571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet, the end-to-end data throughput at software layer on a NoC (Network-on-Chip) platform often cannot match the hardware native speed without an efficient hardware/software interface. In this paper, we present a high-throughput PE-to-PE communication unit with a corresponding driver layer on NoC-based many-core architectures. The proposed communication unit with application-level flow control can handle complicated inter-PE communication for practical parallel applications. The maximum throughput of a unidirectional transmission with flow control protocol at application-level is 2687.3 Mbps (normalized at operating frequency of 100MHz), where the native NoC speed is 3200 Mbps. As a comparison, a software-based protocol is only rated at 148.5 Mbps. The communication unit is also area-efficient at only 19.2K gates, which is roughly 3.2% of a single in-order RISC-based PE.","PeriodicalId":84860,"journal":{"name":"Histoire & mesure","volume":"40 1","pages":"41-44"},"PeriodicalIF":0.0,"publicationDate":"2013-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81086597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The key idea is to exploit predicted input values, which are produced by the model predictive control itself, to speculatively solve an optimal control problem. It is well known that control applications are not suitable for multi- or many-core processors, because feedback-loop systems inherently stand on sequential operations. Since the proposed scheme does not rely on conventional thread-/data-level parallelism, it can be easily applied to such control systems. An analytical evaluation using a real application demonstrates the potential of performance improvement achieved by the proposed speculative executions.","PeriodicalId":84860,"journal":{"name":"Histoire & mesure","volume":"1 1","pages":"17-24"},"PeriodicalIF":0.0,"publicationDate":"2013-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91131599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
