  • The Translational Journey of the Htcondor-CE
    Journal of Computational Science xxx (xxxx) xxx Contents lists available at ScienceDirect Journal of Computational Science journal homepage: www.elsevier.com/locate/jocs Principles, technologies, and time: The translational journey of the HTCondor-CE Brian Bockelman a,*, Miron Livny a,b, Brian Lin b, Francesco Prelz c a Morgridge Institute for Research, Madison, USA b Department of Computer Sciences, University of Wisconsin-Madison, Madison, USA c INFN Milan, Milan, Italy ARTICLE INFO ABSTRACT Keywords: Mechanisms for remote execution of computational tasks enable a distributed system to effectively utilize all Distributed high throughput computing available resources. This ability is essential to attaining the objectives of high availability, system reliability, and High throughput computing graceful degradation and directly contribute to flexibility, adaptability, and incremental growth. As part of a Translational computing national fabric of Distributed High Throughput Computing (dHTC) services, remote execution is a cornerstone of Distributed computing the Open Science Grid (OSG) Compute Federation. Most of the organizations that harness the computing capacity provided by the OSG also deploy HTCondor pools on resources acquired from the OSG. The HTCondor Compute Entrypoint (CE) facilitates the remote acquisition of resources by all organizations. The HTCondor-CE is the product of a most recent translational cycle that is part of a multidecade translational process. The process is rooted in a partnership, between members of the High Energy Physics community and computer scientists, that evolved over three decades and involved testing and evaluation with active users and production infrastructures. Through several translational cycles that involved researchers from different organizations and continents, principles, ideas, frameworks and technologies were translated into a widely adopted software artifact that isresponsible for provisioning of approximately 9 million core hours per day across 170 endpoints.

  • Facilitating E-Science Discovery Using Scientific Workflows on the Grid
    Chapter 13 Facilitating e-Science Discovery Using Scientific Workflows on the Grid Jianwu Wang, Prakashan Korambath, Seonah Kim, Scott Johnson, Kejian Jin, Daniel Crawl, Ilkay Altintas, Shava Smallen, Bill Labate, and Kendall N. Houk Abstract e-Science has been greatly enhanced from the developing capability and usability of cyberinfrastructure. This chapter explains how scientific workflow systems can facilitate e-Science discovery in Grid environments by providing features including scientific process automation, resource consolidation, parallelism, provenance tracking, fault tolerance, and workflow reuse. We first overview the core services to support e-Science discovery. To demonstrate how these services can be seamlessly assembled, an open source scientific workflow system, called Kepler, is integrated into the University of California Grid. This architecture is being applied to a computational enzyme design process, which is a formidable and collaborative problem in computational chemistry that challenges our knowledge of protein chemistry. Our implementation and experiments validate how the Kepler workflow system can make the scientific computation process automated, pipe- lined, efficient, extensible, stable, and easy-to-use. 13.1 Introduction “e-Science is about global collaboration in key areas of science and the next genera- tion of infrastructure that will enable it.”1 Grid computing “coordinates resources that are not subject to centralized control by using standard, open, general-purpose 1 John Taylor, Director General of Research Councils, Office of Science and Technology, UK.

The EU-funded project EMI, now at its second year, aims at providing a unified, high quality middleware distribution for e-Science communities. Several aspects about workload management over diverse distributed computing environments are being challenged by the EMI roadmap: enabling seamless access to both HTC and HPC computing services, implementing a commonly agreed framework for the execution of parallel computations and supporting interoperability models between Grids and Clouds. Besides, a rigourous requirements collection process, involving the WLCG and various NGIs across Europe, assures that the EMI stack is always committed to serving actual needs. With this background, the gLite Workload Management System (WMS), the meta-scheduler service delivered by EMI, is augmenting its functionality and scheduling models according to the aforementioned project roadmap and the numerous requirements collected over the first project year. This paper is about present and future work of the EMI WMS, reporting on design changes, implementation choices and long- term vision.

The EU has over the years funded several big projects in the Grid and now the cloud area, covering besides the high energy physics domain also bioinformatics and medical applications as in image analysis. Bioinformatics and pharmaceutical design have been the major targets of grid applications in Japan. Grids and clouds share many of the same goals and techniques, although clouds are more commercially oriented and privately provided services and grids are rather publicly initiated resource sharing platforms between institutions without strong economic objectives.

  • ARIS and EGIIS Installation, Configuration and Usage Manual
    NORDUGRID NORDUGRID-MANUAL-21 2/5/2017 ARIS and EGIIS Installation, Configuration and Usage Manual O. Smirnova, M. Ellert, D. Johansson Abstract In order to create a Grid infrastructure using ARC-enabled computing resources, information descrip- tion and aggregation services need to be deployed. ARIS is coupled to a computing resource and collects information about it. EGIIS keeps a list of ARIS instances, and eventually, of other EGIIS instances lower down in hierarchy. Top-level EGIIS instances thus serve as an entry point to the Grid, allowing to discover all the resources. 1 Introduction In a distributed computing world, discovery of necessary resources and services is a key to enabling functional infrastructures. In order to be discovered and consequently used, a Grid resource or service must accomplish these two tasks: 1. advertise itself to potential clients in a standard manner, 2. expose relevant information about itself via a standard interface. In ARC, these functionalities are implemented in the ARIS component (Section 3). Given the potentially very large number of Grid resources and services advertising themselves, a hierarchical structure of organising information published by them is necessary in order to avoid bottlenecks. Such an hierarchy is often implemented by using information aggregating or indexing services, kind of \super-peers". Such an indexing service in ARC is implemented in EGIIS (Section 4). While ARIS is coupled to a resource, EGIIS is an independent service. A typical Grid resource owner always has to deploy ARIS∗. EGIIS servers, on the other hand, are normally deployed by the overall Grid infrastructure operators. A system effectively created by ARIS and EGIIS services is called the ARC Information System.

Marohnica 5, Zagreb, Croatia E-mail: [email protected] Tiziana Ferrari EGI.eu Science Park 140, Amsterdam, The Netherlands E-mail: [email protected] The European Grid Infrastructure (EGI) is a distributed computing infrastructure (DCI) that provides more than 320,000 logical CPUs and 152 PB of disk space and data. EGI provides a set of basic operational interfaces that enable efficient management of the distributed computing environment and coordination of all stakeholders. This paper describes the tools, interfaces and procedures that allow the integration of resources based on different software stacks into EGI. The integration relies on the operational interfaces of the tools that support daily operations: configuration management, monitoring, the operations dashboard, support and accounting. In parallel the operational interfaces are being extended in order to enable the integration with other resource infrastructures such as PRACE and EUDAT. 1 Speaker Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence. http://pos.sissa.it PoS(ISGC 2013)010 The International Symposium on Grids and Clouds (ISGC) 2013 March 17-22, 2013 PoS(ISGC 2013)010 Academia Sinica, Taipei, Taiwan 1.

Simon3 1 Laborat´orio de Instrumenta¸c~aoe F´ısicaExperimental de Part´ıculasLisboa, Portugal [email protected] 2 Instituto de Fisica de Cantabria, CSIC, Santander, Spain 3 Fundacion Centro de Supercomputacion de Galicia, Santiago de Compostela, Spain Abstract. The European Grid Initiative (EGI) will provide a sustainable pan-European Grid computing infrastructure for e-Science based on a net- work of regional and national Grids. Although EGI will emerge from the structure established by the project Enabling Grids for E-SciencE (EGEE), the organizational and operational aspects will be deeply changed. The transition to the new model will also impact on the middleware develop- ment and deployment issues. Under the new model, Ibergrid is now coordi- nating the middleware deployment processes in EGI. This paper describes the EGI middleware strategy and the middleware rollout workflow being planned by Ibergrid for the whole European infrastructure. 1 Introduction The European Grid Initiative (EGI.eu) [1, 3] aims to setup an organization that will enable the sustainable provision of grid computing services to the research community in Europe. EGI will provide a mechanism whereby national resources will be fully integrated into a pan-European infrastructure. The mechanism and interfaces for resource integration and software provision for users and application support will form the basis of the EGI coordination work. To this end EGI will provide the necessary middleware by partnering with several external software providers.
