Instead, mixed workloads are processed by each core which leads to system noise (i.e., interferences, scheduling overheads) and yields subpar performance, only. We therefore propose a system design based on Asynchronous Abstract Machines (AAMs). An AAM features a light-weight scheduler and is dedicated to a specific group of tasks with common characteristics (i.e., shared code and data). It offers an asynchronous, task-based interface for efficient interaction between AAMs. Just like applications are built from AAMs, even the OS itself consists of AAMs that are interfaced by applications via asynchronous messages instead of synchronous system calls. A dedicated OS component, which is aware of all AAMs in the system, is responsible for dynamic and exclusive allocation of cores to AAMs depending on their current workload. Thus, cores rarely switch between heterogeneous workloads of different AAMs. And, at the same time, frequent switches between homogeneous tasks become fast, local operations of an AAM, which do not involve the OS kernel. In this paper, we describe shortcomings of existing operating systems, our new system design concept, and present evaluation results of our prototype implementation.","PeriodicalId":365438,"journal":{"name":"Proceedings of the 9th International Workshop on Runtime and Operating Systems for Supercomputers","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126057180","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}

However, conventional performance tools suffer from significant time/space overhead due to the ever-increasing problem size and system scale. For instance, memory monitoring is of critical use in understanding applications and evaluating systems. Due to the dynamic nature in programs' memory accesses, common practice today leaves large amounts of address examination and data recording at runtime, at the cost of substantial performance overhead. On the other hand, the cost of source code analysis is independent of the problem size and system scale, making it very appealing for large-scale performance analysis. Inspired by this observation, we have designed a series of light-weight system software for HPC systems, such as a memory access monitoring tool, a performance variance detection tool , and a communication trace compression tool. In this talk, I will share our experience on building these tools through combining static analysis and runtime analysis and also point out main challenges in this direction.","PeriodicalId":365438,"journal":{"name":"Proceedings of the 9th International Workshop on Runtime and Operating Systems for Supercomputers","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126107855","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}
