Minisymposium: The Many Faces of Simulation for HPC

Abstract – In the field of HPC research and development, simulation has mainly been used for the purpose of evaluating and comparing the performance of application implementations and of the algorithms therein. While this use remains critical, for good reasons, many other compelling use cases have emerged. These have often been made possible by recent advances in the simulation methodologies at the core of available simulation frameworks. Examples of new areas in which simulation has become a compelling proposition include debugging and verification, application/simulation co-design, and HPC education. In this multi-part mini-symposium, we bring together researchers who have contributed to traditional and explored emerging uses of simulation of HPC systems and applications. The objective is for them to share their experiences, present recent results, identify areas of convergence, and discuss future directions.

Bridging Concepts and Practice in eScience via Simulation-driven Engineering

The CyberInfrastructure (CI) has been the object of intensive research and development in the last decade, resulting in a rich set of abstractions and interoperable software implementations that are used in production today for supporting ongoing and breakthrough scientific discoveries. A key challenge is the development of tools and application execution frameworks that are robust in current and emerging CI configurations, and that can anticipate the needs of upcoming CI applications. This paper presents WRENCH, a framework that enables simulation- driven engineering for evaluating and developing CI application execution frameworks. WRENCH provides a set of high- level simulation abstractions that serve as building blocks for developing custom simulators. These abstractions rely on the scalable and accurate simulation models that are provided by the SimGrid simulation framework. Consequently, WRENCH makes it possible to build, with minimum software development effort, simulators that that can accurately and scalably simulate a wide spectrum of large and complex CI scenarios. These simulators can then be used to evaluate and/or compare alternate platform, system, and algorithm designs, so as to drive the development of CI solutions for current and emerging applications.

WORKS 2018 Proceedings

The proceedings of the 13th Workflows in Support of Large-Scale Science Workshop is now available.

The Workshop on Workflows in Support of Large-Scale Science (WORKS) has been established as a premier forum on all aspects in relation to scientific workflows. The 13th edition of the workshop, WORKS 2018, co-located with SC18 in Dallas, Texas, USA, followed the successful tradition of previous years (Paris, 2006; Monterey Bay, 2007; Austin, 2008; Portland, 2009; New Orleans, 2010; Seattle, 2011; Salt Lake City, 2012; Denver, 2013; New Orleans, 2014; Austin, 2015; Salt Lake City, 2016; Denver, 2017). WORKS 2018 focuses on the many facets of data- intensive workflow management systems, ranging from data-intensive workflows representation and enactment to scheduling and resource allocation to provenance to workflow enactment on heterogeneous architectures as well as workflow tools and support environments.

The Call for Papers attracted 19 submissions. After a rigorous review process where each paper received at least two reviews, 8 papers were accepted for a full presentation (acceptance rate 42%). The workshop took place on Sunday, 11 November 2018 and the program also featured an invited keynote by Ilkay Altintas, three lightning talks and a panel discussion. The proceedings include the eight full papers accepted and presented at the workshop. We would like to thank the authors, the presenters, the general chair, the steering committee, the publicity chairs, the program committee, and the SC18 workshop chairs – without their excellent work and contributions WORKS would not be successful.
