hearing about the experiments, many people start off by saying "Well, this is interesting, but what
if (assumption) was (some slightly different value) instead of what you used" The gateway
should allow users to experiment with moderately computationally intensive experiments to
address these questions.
This work is in the early prototype stage.
Social Informatics Data Grid (SIDGrid).
The team has improved portability of existing gadgets (tunneling requests through container;
gadget-gadget communication using HTML5 facilities), and tested these in an iGoogle container.
Client-side script and server-side support have been developed to simplify the introduction of
new applications into the portal. Work began to expose multiple local and remote compute
resources through portal.
SIDGrid developer Tom Uram presented demonstrations of his work at the Argonne booth at
SC10 and also served as a committee member for the Gateway Computing Environments
workshop the conference.
Support continues for OOPS (protein simulation) users of portal, including the addition of new
scripts to the portal.
Next quarter plans include implementation of a data management front-end to allow users to
upload, manage, and process data using gadget-based applications defined in the portal.
Alternatives will be investigated for managing applications available to portal, including
integration with source code management systems used by scientists. Work will continue on
gadget portability, including testing in third-party containers such as iGoogle and OGCE.
Approaches will be evaluated for single sign-on in gadget context so that users won’t have to
authenticate with each gadget in a container page.
Support for groups using the OOPS (Open Protein System) portal will continue.
GCE Workshop.
The IU Science Gateway team organized the sixth Gateway Computing Environments (GCE)
workshop at Supercomputing 2010. This year’s workshop featured presentations of 13 peerreviewed
papers to be published in IEEE Digital Proceedings. The one day workshop was
attended by approximately 50 people. Presentations and additional information are available
from the workshop website, http://www.collab-ogce.org/gce10/index.php/Main_Page.
UltraScan.
The Indiana University Science Gateway team worked with Prof. Borries Demeler and Dr. Emre
Brookes of the University of Texas Health Science Center to transition their UltraScan science
gateway infrastructure from TACC’s Lonestar to Ranger systems. This involved removing
UltraScan dependencies on Globus GRAM4 and significant testing of Ranger’s new GRAM5 job
manager (documented in previous quarterly reports). UltraScan now uses the GFAC service
developed by the Open Gateway Computing Environments (OGCE) to manage its
ultracentrifugation experimental data analysis. GFAC’s capabilities include masking the
differences between GRAM versions. During the current reporting quarter, UltraScan’s Ranger
allocation usage went from 0 to 57,747 SUs. The IU team is also assisting the UltraScan team as
it develops its next generation software (UltraScan3, led by Dr. Bruce Dubbs). Both UltraScan2
and UltraScan3 use IU’s Gateway Hosting Service for significant testing and development. IU
work was led and performed by Suresh Marru and Raminder Singh, with assistance from
Patanachai Tangchaisin (student intern). As part of this overall effort, the Indiana University
Science Gateway team worked closely with Globus developers and TACC & LONI system
