John Cobb presented the capstone talk at the NOBUGS 2010 conference describing the NSTG<br />
activities and integration with SNS as a “Best practice” for the integration of national<br />
cyberinfrastructure with an experimental user facility. Cobb was also on the conference<br />
<strong>org</strong>anizing committee.<br />
GISolve.<br />
This team continues to explore new applications and communities for high performance<br />
computing. Recent interactions have been with the land use science community. Future plans<br />
include working with a public health community. Several publications from the group are listed<br />
in this report’s appendices.<br />
CCSM/ESG.<br />
The joint team is making progress as planned in all three major project areas. Next quarter,<br />
overarching goals include completion of work on software licensing and the completion of phase<br />
I of the prototype CESM1 gateway. This will support running CESM1 simulations on Steele,<br />
automatic production of attributes, and automatic publishing of model output to ESG.<br />
Task 1 is to provide interfaces for remote model run invocation. CESM1 is being tested on Steele<br />
at Purdue. The team has partially resolved the MPI communication problem, but there are still<br />
some problems scaling up. CESM-WS web service interfaces have been deployed to a production<br />
server, including bug fixes and performance improvements. Incremental changes support new<br />
requirements from the CESM1 gateway client. The CESM1 gateway directly invokes the CESM-<br />
WS interfaces and currently supports case creation/configuration/submission and status tracking<br />
Next quarter the team will address the CESM1 scaling issues, complete model validation and add<br />
support for data access and publishing of model output from the prototype CESM1 gateway to<br />
ESG.<br />
Task 2 is to publish Purdue CCSM archive data to ESG. Memory of the Purdue ESG data node<br />
has been upgraded. The FUSE interface to the ESG test gateway has been tested and successfully<br />
published (manually) an iRODS CCSM3 data collection through this interface.<br />
Next quarter the team will automate publishing of model output from the CESM1 gateway to<br />
ESG test gateway.<br />
Task 3 is to collect and publish CESM1 model data and metadata back to ESG. Work continues<br />
on instrumenting CESM such that it can produce a METAFOR-compliant CIM document<br />
(WCRP/CMIP5 metadata). Support was added for outputting ESMF attributes from the CESM<br />
components and driver, and the attribute suite was further analyzed. Tested the system, and<br />
provided code back to CESM team for integration. The team completed development of an initial<br />
version of an ATOM feed for ingesting CIM documents into ESG. Integration of the feed was<br />
tested with ESG, publishing model metadata back into it.<br />
Next quarter the team plans to review metadata content and completeness by Purdue, add code to<br />
CESM to automatically set attributes from within CESM code, integrate as CESM tagged release,<br />
and test at Purdue. Packaging of the ATOM feed will be refined and released in a V1.0.0 open<br />
source version. Basic installation and usage documentation will be completed and deployed at<br />
Purdue.<br />
Purdue Environmental Data Portal.<br />
The Environmental Data Portal has integrated three new data sets, the Indiana precipitation<br />
dataset, St. Joseph watershed water quality and stream flow data and a historical time series of<br />
average precipitation and temperature data for Midwest.<br />
