While Deep Neural Networks (DNNs) have enabled state-of-the-art accuracy in many intelligence tasks, they are notoriously expensive and difficult to deploy in hyperscale datacenters constrained by power, cost, and latency. Furthermore, the escalating (and insatiable) demand for DNNs comes at an inopportune time as ideal silicon scaling (Moore's Law) comes to a diminishing end. At Microsoft, we have developed a new cloud architecture that's enhanced using FPGA (Field Programmable Gate Array). FPGAs can be viewed as programmable silicon and are being deployed into each and every new server in Microsoft's hyperscale infrastructure. The flexibility of FPGAs combined with a novel Hardware-as-a-Service (HaaS) architecture unlocks the full potential of a completely programmable hardware and software acceleration plane. In this talk, I'll give a history and overview of the project, discuss the key enabling technologies behind our enhanced cloud, present opportunities to harness this technology for accelerated deep learning, and conclude with directions for future work.","PeriodicalId":269197,"journal":{"name":"Proceedings of the 2017 ACM on International Symposium on Physical Design","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125442796","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}

An ideal legalization approach should preserve the quality of the input placement in terms of routability and timing, as well as effectively manage white space availability and have low runtime. In this work, we present a robust legalization algorithm for standard cell placement that minimizes maximum cell movements fast and effectively based on a novel network-flow approach. The idea is inspired by path augmentation but with important differences. In contrast to the classical path augmentation approaches, we resolve bin overflows by finding several candidate paths that guarantee realizable (legal) flow solutions. In addition, we show how the proposed algorithm can be seamlessly extended to handle relevant cell edge spacing design rules. Our experimental results on the ISPD 2014 benchmarks illustrate that our proposed method yields 2.5x and 3.3x less maximum and average cell movement, respectively, and the runtime is significantly (18x) lower compared to best-in-class academic legalizers.","PeriodicalId":269197,"journal":{"name":"Proceedings of the 2017 ACM on International Symposium on Physical Design","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130091792","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}

In order to reduce post-layout circuit performance degradation, critical net wire length minimization should be considered during placement, in addition to the conventional optimization objectives of total area and half perimeter wire length (HPWL). In this paper, we develop effective hierarchical and analytical techniques for high-performance analog circuits placement, which is a complex problem given its multi-objectives and constraints (e.g. hierarchical symmetric groups). The entire circuit is first partitioned hierarchically in a top-down, critical parasitics aware, hierarchical symmetric constraints and proximity constraints feasible manner, where the placement subproblem for each partition at each level can be solved in reasonable run-time. Then, different placement variants are generated for each partition from bottom up, taking advantage of the computation power of modern multi-core systems with parallelization. To assemble the placement variants of different subpartitions, a Mixed Integer Linear Programming (MILP) formulation is proposed which can simultaneously minimize critical parasitic loading, total area and HPWL, and handle hierarchical symmetric constraints, module variants selection and orientation. Experimental results demonstrate the effectiveness of the proposed techniques.","PeriodicalId":269197,"journal":{"name":"Proceedings of the 2017 ACM on International Symposium on Physical Design","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114466939","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}

Although the game industry has been employing modern software development concepts such as data-oriented design, most physical design tools still relies on object-oriented design. Differently from object-oriented design, data-oriented design focuses on how data is organized in memory and can be used to solve typical object-oriented design problems. However, its adoption is not trivial because most software developers are used to think about objects' relationships rather than data organization. The entity-component design pattern can be used as an efficient alternative. It consists in decomposing a problem into a set of entities and their components (properties). This paper discusses the main data-oriented design concepts, how they improve software quality and how they can be used in the context of physical design problems. In order to evaluate this programming model, we implemented an entity-component system using the open-source library Ophidian. Experimental results for two physical design tasks show that data-oriented design is much faster than object-oriented design for problems with good data locality, while been only sightly slower for other kinds of problems.","PeriodicalId":269197,"journal":{"name":"Proceedings of the 2017 ACM on International Symposium on Physical Design","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126294857","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}
