What: Brown Bag Lunch Talk Presented by FAS Research Computing
Who: Miron Livny, Professor of Computer Sciences, Center for High Throughput Computing, University of Wisconsin – Madison
When: October 6, 2014 | 12:30pm-1:30pm
Talk Title: Submit Locally & Run Globally
When first deployed almost 30 years ago at the UW-Madison Computer Sciences Department, HTCondor enabled faculty and students to augment the computing power of their personal workstation with opportunistic cycles offered by other workstations in the department. High Throughput applications where managed locally by the workstation on their desk and executed both locally and remotely. A cornerstone of the design of HTCondor has been to maximize access to remote computing capacity while preserving local autonomy and access to local capacity. HTCondor always viewed users as both providers and consumers of computing capacity. Today, researchers throughout the UW-Madison campus use the same approach to run their applications on compute resources across the campus and across the USA. As a member of the Open Science Grid (OSG) consortium, the UW-Madison Center for High Throughput Computing (CHTC) enables researches who submit their High Throughput application to a personal or departmental HTCondor entry point to harness opportunistic resources on more than 100 OSG sites. Some OSG members use the same approach to harness computing resources provided by commercial clouds. In the talk we will present the distributed computing principals that guided the design of HTCondor and will review how members of the OSG consortium leverage the capabilities of HTCondor to support a broad range of High Throughput applications. We will also discuss the role that the CHTC Research Computing Facilitators play in transitioning researchers to run globally while submitting locally.
