## Integrated Network Environment for Distributed Science

**Objective:**  A ***scalable, secure, integrated, distributed****** ******infrastructure*** to combine scientific resources and expertise across the Office of Science enterprise to address large-scale science projects that no single institution could undertake alone.
**SciDAC encompasses in the *****Collaboratory Software Environment*****:** Research, development, and testing of advanced network technologies, scientific collaboration tools, and frameworks that enable scientists to integrate unique and expensive enterprise research facilities, computing resources, data archives, and expensive instruments into cost-effective virtual laboratories.

**Notes:**
Create a Collaboratory Software Environment to enable geographically separated scientists to effectively work together as a team and to facilitate remote access to both facilities and data.

## Highlights of Impact

- Pilots collaboratories are partnerships between CS/network researchers and discipline scientists that drive the initial technology transfer into a new applications area
- Particle Physics Data Grid
- Production grid (Grid3 testbed operational for 4+ months)
- Earth System Grid
- Web-based portal for catalogued datasets
- Collaboratory for Multiscale Chemical Sciences
- Production informatics environment
- Middleware projects are facilitating the discovery and utilization of scientific data, computers, software, and instruments in a controlled fashion.
- DataGrid Middleware
- Middleware Technology to Support Science Portals.
- New services incorporated into ESnet
- DOE Science Grid provides a certificate authority that has issued over 1500 certificates to a number of organizations (real and virtual)
- Support standards development

**Notes:**
ESG-
We have developed new data management capabilities that provide robust interoperability among DOE (HPSS) and NCAR (MSS) archival systems, and this reflects a close and very productive collaborative effort with the SciDAC Scientific Data Management ISIC. It also earned us the paraphrased comment from a user: “a hundred times faster – and easier!” 
ESG’s current web portal exposes a catalog of approximately one hundred datasets (roughly the last half-decade of simulation activity) with a rich body of semantic and usage-level metadata – a decisive step towards capturing elements of the “scientific notebook” for reuse by a broad community. We are employing powerful new technologies based on the OGSA-DAI project results. 
CMCS
A production informatics infrastructure enabling multi-scale chemical science has been deployed (cmcs.org).   It integrates key collaboration tools, chemistry-specific applications, data resources, and services, such as a Chemical Science Portal enabling data-centric project- and community-level collaboration, XML data/metadata management services enabling annotation and data discovery, and tools for security and notification. This CMCS environment has attracted combustion scientists from around the world who are currently working in seven interacting pilot groups that span the scales and disciplines of this field. 
Goal of supporting collaborative/cooperative work is incorporated into the way we do business
