Abstract

This experiment runs workflows from the domain science of astronomy, but with the intent of inspecting the computer scientific parallel computing, data migration, and workflow aspects of it. Comparable experiments will be run on the same domain data on Amazon and TeraGrid/OSG, and the paper will discuss the observed differences and communalities. This is an extension to the https://portal.futuregrid.org/references/experiences-using-cloud-computing-scientific-workflow-application paper.

Intellectual Merit

The purpose is to gather experimental data on workflows, parallel computing and data migration for a paper to be submitted journal special issue on the topic of Data Intensive Computing in the Clouds.

Broader Impacts

Possible configuration issues on both, the submit machine and the resource VMs, will influence how the Pegasus tutorial is going to be set up and pans out. It may also influence decisions on Experiment Management setup and configuration issues.

Scale of Use

(128 cores x 1 day) for multiple runs, from one or more sites depending on configuration exploration.

Results

(will be posted as paper submission.)
