    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!

    Using the Jetstream Research Cloud to provide Science Gateway resources
    (2017-05) Knepper, Richard; Coulter, Eric; Pierce, Marlon; Marru, Suresh; Pamidighantam, Sudhakar
    We describe the use of the Jetstream research-cloud, a purpose-built system with the goal of supporting “long-tail” research by providing a flexible, on-demand research infrastructure, to provide scalable back-end resources for science gateways. In addition to providing cloud-like resources for on-demand science, Jetstream offers the capability to instantiate long-running clusters which support science gateways. Science gateways are web-based systems built on computational infrastructure which provide commonly-used tools to a community of users. We created a persistent cluster on the Jetstream system which is connected to the SEAGrid science gateway and provides additional compute resources for a variety of quantum chemistry calculations. We discuss the further application of toolkits provided by the Extreme Science and Engineering Discovery Environment (XSEDE) to build general-purpose clusters on the research cloud.
