ABIDES is designed from the ground up to support agent-based research in market applications. While proprietary simulations are available within trading firms, there are no broadly available high-fidelity market simulation environments. ABIDES enables the simulation of tens of thousands of trading agents interacting with an exchange agent to facilitate transactions. It supports configurable pairwise noisy network latency between each individual agent as well as the exchange. Our simulator's message-based design is modeled after NASDAQ's published equity trading protocols ITCH and OUCH. We introduce the design of the simulator and illustrate its use and configuration with sample code, validating the environment with example trading scenarios. The utility of ABIDES for financial research is illustrated through experiments to develop a market impact model. The core of ABIDES is a general-purpose discrete event simulation, and we demonstrate its breadth of application with a non-finance work-in-progress simulating secure multiparty federated learning. We close with discussion of additional experimental problems it can be, or is being, used to explore, such as the development of machine learning trading algorithms. We hope that the availability of such a platform will facilitate research in this important area.","PeriodicalId":422248,"journal":{"name":"Proceedings of the 2020 ACM SIGSIM Conference on Principles of Advanced Discrete Simulation","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125159594","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}

ModSim as a science and practice will be discussed from the perspectives of methods and tools and its myriad of uses, such as system-application co-design, performance prediction, or system and application optimization. To achieve this demanding goal, the presentation initially will offer an analysis and critique of the traditional methodologies and their state of the art. Then, attention will focus on new ideas related to machine learning-both as an increasingly important application workload and a method for ModSim. The context of mapping these applications to leading-edge systems will include analysis and the need for \"dynamic performance modeling\" as an actionable way to optimize effectively for performance during execution. Throughout, particular emphasis will be on methods and practices that are practical, accurate, and can be applied to extreme-scale computing (as broadly defined).","PeriodicalId":422248,"journal":{"name":"Proceedings of the 2020 ACM SIGSIM Conference on Principles of Advanced Discrete Simulation","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125307866","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}

Demand-Driven PDES: Exploiting Locality in Simulation Models 需求驱动的PDES:利用仿真模型中的局部性

At the same time, many real-life simulation models exhibit significant execution locality, where only part of the model (and thus a subset of threads) are actively sending or receiving messages in a given time period. These inactive threads still continuously check their queues and participate in simulation-wide time synchronization mechanisms, such as computing Global Virtual Time (GVT). This wastes resources, ties up CPU cores with threads that offer no contribution to event processing and limits the performance and scalability of the simulation. In this paper, we propose a new paradigm for managing PDES threads that we call Demand-Driven PDES (DD-PDES). The key idea behind DD-PDES is to identify threads that have no events to process and de-schedule them from the CPU until they receive a message requiring event processing. Furthermore, these inactive threads are also excluded from participation in the GVT computation, accelerating that process as a result. DD-PDES ensures that the CPU cycles are mostly spent on actual event processing, resulting in performance improvements. This architecture allows for significant over-subscription of threads by exceeding the number of available hardware thread contexts on the chip. We demonstrate that on a Knights Landing processor, DD-PDES significantly outperforms the traditional simulation equipped with the best currently proposed GVT algorithms.","PeriodicalId":422248,"journal":{"name":"Proceedings of the 2020 ACM SIGSIM Conference on Principles of Advanced Discrete Simulation","volume":"21 10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131164486","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}
