Domain Science Applications

New Spiral 4 AwardEvaluate GENI’s ability to support computational science.

Are the current GENI technologies capable of effectively supporting the computing needs of domain science?

What are the benefits and limitations of current GENI technologies with respect to supporting the needs of domain science?


The 18th GENI Engineering Conference

October 27-29, 2013

Polytechnic Institute of New York

University, Brooklyn, NY

High Throughput Computational Genomics: Identification of functional domains and the identification of conserved functional relationships across large numbers of genomes.

Workflow ensemble (Pegasus/

HTCondor)Task data sets on the order of 50-100 GB.Implicit iterationScales to 1000s of tasks

GENI has matured to the point where it is now time to


its capabilities with respect to

domain science applications “at scale” and use the results of this evaluation to inform the direction of future GENI development.There is an opportunity to introduce domain scientists to the GENI-way-of-thinking about networking and distributed systems in order to seed the dissemination of GENI technologies to existing and future high throughput and high-performance computing centers.




the GENI experiment workflow

to domain science applications and evaluate GENI’s ability to run domain science experiments (performance and ease-of-use).Build a tool for domain scientists to create RSpec from high-level descriptions of high-throughput and high-performance applications.Provide feedback to GENI rack developers on the current capabilities with respect to science applications as well as target areas for improvement.Bonus Goal: Attract domain scientists to GENI


Outreach to




Provisioning Overhead of creating, destroying, and modifying slices.GENI for big-data. Large workflow inputs/outputGENI for MPI. Tightly coupled

Tool for deploying domain science applications easily.

Introducing domain scientists to GENI.
