Collaborators
We collaborate with many domain scientists, some examples of our collaborations can be found here.
We also collaborate with computer scientists in the following areas:
Workflow Creation:
- Wings, lead by Yolanda Gil at USC/ISI, allows for semantic-rich workflow composition
- Triana, lead by Ian Taylor at Cardiff University, provides a graphical interface to Pegasus (in propototype)
- Kepler, lead by Ilkay Altintas (UCSD) and Bertram Ludaescher (UCDavis), provides a graphical interface to Pegasus (see current status)
Workflow Execution:
- DAGMan, lead by Miron Livny at University of Wisconsin Madison, provides a robust and scalable execution engine.
- GRMS, lead by Jarek Nabrzyski from the Poznan Supercomputing Center, provides resource brokering capabilities
Workflow Provenance:
- PASOA, led by Luc Moreau from the University of Southampton, UK. We are integrating Pegasus with PASOA to be able to keep track of provenance information as the workflow is executing. Some of our progress can be seen here.
- We are also participating in the Provenance Challenge--our entry can be found here.
Workflow Scheduling:
- We are working with Rizos Sakellariou, University of Manchester on issues of scheduling in data storage-aware scheduling, see our CCGrid 2007 paper.
Workflow Provenance Logging via Netlogger:
- We are working with Brian Tierney, Dan Gunter and Keith Beattie from Lawerence Berkeley National Laboratory on issues of logging the Pegasus worklfow provenance record into their Netlogger System. See initial work here done to populate and query pegasus provenance records for the SCEC workflows.
