Using Comet’s Virtual Clusters

Sign up or log in to save this to your schedule and see who's attending!

Comet is an XSEDE HPC resource hosted and operated at SDSC. This tutorial introduces the virtual cluster capability of Comet, a unique feature that provides research groups, projects, and campuses with the ability to fully define their own software environment with a set of dynamically allocated virtual machines. This tutorial introduces Comet's virtual cluster capability, and has hands on material to cover the different modes of usage anticipated for virtual clusters. We begin the tutorial with an overview of the Comet system architecture, the design and architecture of the virtual cluster capability, and how it compares to other virtualized and cloud services. The high performance of the virtualized clusters combining the full AVX2 feature set of the Haswell processors and the InfiniBand HCAs using SR-IOV for MPI will be covered. We then follow with information on how to build, configure, and manage virtual clusters using the Cloudmesh client, a tool to easily interface with multiple clouds from the command line and a command shell. The hands-on section of the tutorial is divided into three sections: Installing and configuring a virtual cluster; Running MPI applications within the virtual cluster; Simple automation to start and stop virtual machines dynamically. SDSC and IU Staff will be available to meet with individual users, to further discuss usage of Comet, at the conclusion of the tutorial. This tutorial is appropriate for people with Linux system administration or management experience. HPC cluster management experience is not required but participants with this experience will benefit the most from this tutorial. Tutorial attendees wishing to participate in the hands-on portion of the tutorial will require a laptop with either VirtualBox or Python 2.7.x with virtualenv. Instructors will provide a Linux VM for VirtualBox users or attendees can install the Cloudmesh client tool in a Python virtualenv directly on their laptop.
