M.S. Paper Title: Cybershake on opportunistic cyberinfrastructures

Abstract:
Continued improvements in provisioning capabilities of
cyberinfrastructures increase the computational enablement of science
such as the Cybershake application. Using workflow tools such as Swift
and Pegasus, we observed how jobs are scheduled to exploit an expanded
set of resources available in TeraGrid and Open Science Grid (OSG).
Our tests on OSG gave 2000~CPUs in a day on an opportunistic basis.
This was well within the time-to-solution requirements of the
Cybershake application. However, there were potential bottlenecks in
the data requirements of the application. In this paper, we
characterize how the time-to-solution budget is spent by looking at
the running time and file transfer time of the post-processing
computation.

Allan's advisor is Prof. Ian Foster
