    Research Computing at a Business University
    (PEARC 2019, 2019-07-30) Wells, Jason; Coulter, J. Eric
    Research Computing demands are exploding beyond traditional disciplines due to the proliferation of data in all walks of life. At Bentley University ("Bentley"), a business university in the Boston area, this expansion has been most readily seen in our Account- ing, Economics, Mathematics, and Natural Sciences departments. The result has been a small effort to build a research computing capability at this small New England university. This poster will serve as an overview of the steps taken to build such an effort at a business university, the revelations we have had along the way, and our plans for the future

    Programmable Cyberinfrastructure: Introduction to Building Clusters in the Cloud
    (PEARC 2017, 2017-07-10) Coulter, Eric; Fischer, Jeremy; Knepper, Richard; Reynolds, Resa
    Cloud computing is growing area for educating students and performing meaningful scientific research. The challenge for many educators and researchers is knowing how to use some of the unique aspects of computing in the cloud. One key feature is true elastic computing - resources on demand. This can be as simple as being able to provision a single purpose-driven virtual machine by hand quickly and easily. It can be taken a step further into creating scripted launch of additional resources as needed. Beyond that, elastic computing techniques can go to the next level and create modest virtual clusters on demand. While cloud resources won't replace traditional HPC environments for large research projects, there are many smaller research and education projects that would benefit from the highly customizable, highly configurable, programmable cyberinfrastructure afforded by cloud computing environments. This tutorial will discuss the basic methods required for interacting with elastic computing environments. It will then show a hands-on approach to creating virtual clusters in an Openstack environment. Please come prepared with a laptop with working wireless internet, and the following packages installed: Python 2.7 or later, setuptools, pip (the following pip packages may be installed in a virtualenv if you are comfortable with that!), "pip install python-glanceclient python-cinderclient python-openstackclient python-novaclient python-neutronclient python-keystoneclient python-heatclient shade". The goal is to have a working openstack client interface on your machine; for more details, see: https://docs.openstack.org/user-guide/common/cli-install-openstack-command-line-clients.html Required reading: It would be useful to explore the Jetstream wiki: https://wiki.jetstream-cloud.org - Particularly the sections on using the Jetstream API! We will provide training accounts and working openrc.sh files during the session!

    XCBC and XNIT - tools for cluster implementation and management in research and training
    (2015-08-17) Fischer, Jeremy; Knepper, Richard; Coulter, Eric A.; Peck, Charles; Stewart, Craig A.
    The Extreme Science and Engineering Discovery Environment has created a suite of software designed to facilitate the local management of computer clusters for scientific research and integration of such clusters with the US open research national cyberinfrastructure. This suite of software is distributed in two ways. One distribution is called the XSEDE-compatible basic cluster (XCBC), a Rocks Roll that does an “all at once, from scratch” installation of core components. The other distribution is called the XSEDE National Integration Toolkit (XNIT), so that specific tools can be downloaded and installed in portions as appropriate on existing clusters. In this paper, we describe the software included in XCBC and XNIT, and examine the use of XCBC installed on the LittleFe cluster design created by the Earlham College Cluster Computing Group as a teaching tool to show the deployment of XCBC from Rocks. In addition, the demonstration of the commercial Limulus HPC200 Deskside Cluster solution is shown as a viable, off-the-shelf cluster that can be adapted to become an XSEDE-like cluster through the use of the XNIT repository. We demonstrate that both approaches to cluster management – use of SCBC to build clusters from scratch and use of XNIT to expand capabilities of existing clusters – aid cluster administrators in administering clusters that are valuable locally and facilitate integration and interoperability of campus clusters with national cyberinfrastructure. We also demonstrate that very economical clusters can be useful tools in education and research.

    XCBC & XNIT using the LittleFe and Limulus HPC200
    (2015-07-27) Fischer, Jeremy; Coulter, Eric A.; Hallock, Barbara; Knepper, Richard
    For this tutorial, we wish to demonstrate building practical XSEDE Compatible Basic Clusters (XCBC) while showing that an XCBC need not be an expensive resource to be useful. One secondary goal is showing the basic process of installing Rocks on a â bare metalâ system from start to finish, ultimately running a basic multi node job that will demonstrate the abilities of such a system. The next secondary goal is to show using Yum and RPMs developed by XSEDE to create an XCBC. Also, we want to demonstrate the value of using a small local cluster to pilot and prototype research in order to better prepare for requesting allocations on national XSEDE resources. An additional goal is to inspire those that may have limited system administration resources and/or limited budgets into finding ways to develop clusters to meet their needs for experimentation or for smaller research jobs that might not otherwise get time on XSEDE systems. Lastly, we will cover the basics of management for small clusters, getting started and managing users effectively.

    XSEDE Value Added, Cost Avoidance, and Return on Investment

    In science and engineering discovery often lags years behind research, whose full potential may not be known for decades. Large research facilities struggle to quantify a return on the substantial federal investments that fund their often-broad scopes of operations. This paper presents a three-part methodology that shows the value from the investment in XSEDE: 1) a qualitative examination of the primary areas where XSEDE adds value to the open research community, 2) a “thought model” examining the savings realized by the National Science Foundation (NSF) through the centralization and coordination XSEDE provides, and 3) an assessment of the value provided to Service Providers in the XSEDE ecosystem. XSEDE adds significantly to the US research community because it functions as a unified interface to the XD ecosystem and because of its scale. We cannot yet put a figure on this value but according to anecdotal evidence it is significant – perhaps greater than the entire cost of XSEDE over five years. We can qualitatively assess return on investment (ROI) for XSEDE’s delivery of essential core functions for a national advanced cyberinfrastructure center. A partly quantitative, partly qualitative analysis suggests ROI for XSEDE’s delivery of essential core functions to the nation is greater than 1.0. Qualitative arguments considering anecdotal evidence of XSEDE’s value added suggest XSEDE has an ROI of greater than 1.0 in terms of return to the nation on the NSF investment in XSEDE.

    What is campus bridging and what is XSEDE doing about it?
    (2015-07-15) Stewart, Craig A.; Knepper, Richard; Ferguson, James; Bachmann, Felix; Foster, Ian; Grimshaw, Andrew; Hazlewood, Victor; Lifka, David
    The term “campus bridging” was first used in the charge given to an NSF Advisory Committee for Cyberinfrastructure task force. That task force developed this description of campus bridging: “Campus bridging is the seamlessly integrated use of cyberinfrastructure operated by a scientist or engineer with other cyberinfrastructure on the scientist’s campus, at other campuses, and at the regional, national, and international levels as if they were proximate to the scientist, and when working within the context of a Virtual Organization (VO) make the ‘virtual’ aspect of the organization irrelevant (or helpful) to the work of the VO.” Campus bridging is more a viewpoint and a set of approaches to usability, software, and information concerns than a particular set of tools or software. We outline here several specific use cases that have been identified as priorities for XSEDE in the next four years. These priorities include documentation, deployment of software used entirely outside of XSEDE, and software that helps bridge from individual researcher to campus to XSEDE cyberinfrastructure. We also describe early pilot tests and means by which the user community may stay informed of campus bridging activities and participate in the implementation of Campus Bridging tools created by XSEDE. Metrics are still being developed, and will include (1) the number of campuses that adopt and use Campus Bridging tools developed by XSEDE and (2) the number of and extent to which XSEDE-developed Campus Bridging tools are adopted among other CI projects.

    Methods For Creating XSEDE Compatible Clusters
    (Association for Computing Machinery (ACM), 2014-07-13) Fischer, Jeremy; Knepper, Richard; Standish, Matthew; Stewart, Craig A.; Alvord, Resa; Lifka, David; Hallock, Barbara; Hazlewood, Victor
    The Extreme Science and Engineering Discovery Environment has created a suite of software that is collectively known as the basic XSEDE-compatible cluster build. It has been distributed as a Rocks roll for some time. It is now available as individual RPM packages, so that it can be downloaded and installed in portions as appropriate on existing and working clusters. In this paper, we explain the concept of the XSEDE-compatible cluster and explain how to install individual components as RPMs through use of Puppet and the XSEDE compatible cluster YUM repository.
