Therefore, when using such platforms, it is important to adopt a Design Space Exploration (DSE) strategy that considers compromises among different objectives. Existing DSE approaches are generally based on evolutionary algorithms to solve Multi-Objective Optimization Problems (MOOPs) by minimizing a linear combination of weighted cost functions (i.e., Weighted Sum Method, WSM). In this way, the main issues are related to reduce timing execution while trying to improve the evolutionary algorithm performance, introducing strategies that attempt to bring better solutions. Code parallelization is one of the most used approaches in this field, but no standard methods have been released since different aspects could affect the performance. This approach leads to exploit parallel and distributed processing elements in order to implement evolutionary algorithms. In the latter case, if we consider genetic algorithms, it is possible to talk about Parallel Genetic Algorithms (PGA). Considering this context, this paper focuses on DSE for heterogeneous multi-processor embedded systems and introduces an improvement that reduces execution time using parallel programming languages (i.e., OpenMP) inside the main genetic algorithm approach, while trying to lead to better partitioning solutions. The descriptions of the adopted DSE activities and the OpenMP implementation, validated by means of a case study, represent the core of the paper.","PeriodicalId":38836,"journal":{"name":"Meta: Avaliacao","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83301842","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 main characteristics of these applications are high computational demand, real-time interaction with the environment, security, low power consumption, and local autonomy, among others. Addressing these diverse characteristics, researchers have proposed heterogeneous multicore embedded systems comprising CPUs, GPUs, FPGAs, and ASICs. Whereas each computing element provides a unique capability to enable one of the application characteristics, collaborating these processing cores in running an application to get the maximum performance is a crucial challenge. This paper considers the collaborative usage of a multicore CPU and an FPGA in a heterogeneous embedded system to improve the performance of sparse matrix operations, which have been essential techniques in reducing the inference complexity in machine learning techniques, especially deep convolutional neural networks. Experimental results show that the collaborative execution of sparse-matrix-dense-matrix multiplication on the Xilinx Zynq MPSoC, a heterogeneous CPU+FPGA embedded system, can improve the performance by a factor of up to 42% compared with just using the FPGA as an accelerator.","PeriodicalId":38836,"journal":{"name":"Meta: Avaliacao","volume":"71 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75060532","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}

While the goal of executing programs requires the unambiguity of a formal language, programmers use natural language within these formal constraints to explain implemented concepts to each other. This so called naturalness – the property of programs to resemble human communication – motivated many statistical and machine learning (ML) approaches with the goal to improve software engineering activities. The metaprogramming facilities of most programming environments model the formal elements of a program (meta-objects). If ML is used to support engineering or analysis tasks, complex infrastructure needs to bridge the gap between meta-objects and ML models, changes are not reflected in the ML model, and the mapping from an ML output back into the program’s meta-object domain is laborious. In the scope of this work, we propose to extend metaprogramming facilities to give tool developers access to the representations of program elements within an exchangeable ML model. We demonstrate the usefulness of this abstraction in two case studies on test prioritization and refactoring. We conclude that aligning ML representations with the program’s formal structure lowers the entry barrier to exploit statistical properties in tool development.","PeriodicalId":38836,"journal":{"name":"Meta: Avaliacao","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89707234","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}
