This talk gives the review committee needed background information on Fusion Energy research as only one committee member is from the Fusion community.
Schissel, NFC Project Overview, 30 minute talk/ 5 - 10 minutes questions.
Draft viewgraphs in PowerPoint
This talk needs to set up the entire day. It must take the introduction
just given and outine why the NFC is critical. It will give an overview
of the accomplishments of the project and act as an introduction to
all subsequent talks. It will be the summary of the review placing
the details to come later in context. This will allow individuals
to present their results yet allow the reviewers to see the project
as one unified whole.

Establishment of DOE Grids CA as a means of meeting the Fusion Gridıs need for X.509 certificates.
o Part of the original NFC proposal was that we would start out with the DOE
Science Grid CA to issue certificates and then switch to running one of our own.
o Part of the LBNL contribution was to act as a liaison to the DOE science Grid CA
and to contribute to the DOE Grids CA Certificate Policy and Practices statement so
that the new CA could handle the NFCıs certificates needs. As
o A result it is no longer a requirement for the Fusion Grid to run its own CA
o The NFC is one of the founding DOE Grids members and I function as the NFC Registration
Authority and representative on the DOE Grids Policy Management Association (PMA).
Fine-grained access control for job submission.
o Working with the Globus team at ANL we have integrated Akenti fine grained access
control with the Globus job manager.
o We did an early prototype for SC01 demo where the Globus job manager called out to
Akenti on job submission only. Akenti checked to see that the user was requesting a known
and authorized binary to be executed. This restricted the default Globus behavior, where any
user in the gridmap file could execute any binary on the system. It also got NFC members used
to using x.509 certificates for access to remote resources.
o A second prototype was built for the SC02 demos, where the job manager would call Akenti for
decisions on job control as well as job submission. The analysis of the RSL request was added
to the job-manager code, and the Akenti access policy was written to control specific RSL
requested parameter such as compute time and memory requirements.
o We are currently working on a third version that will move the RSL analysis out of the job
manager module into a plugable authorization module. This module will be called from the
job manager with the userıs security context and RSL request. It will call the Akenti server
with the userıs X.509 certificate and the resource name. It will then interpret the returned value,
if it includes conditional actions, and return a simple allowed or denied result to the job manager.

-- (very brief) overview of TRANSP & its role in fusion science
-- NFC TRANSP service implementation at PPPL
-- use of MDSplus (MIT).
-- use of Globus (ANL), Akenti (LBNL).
-- use of FGM (GA) & TRANSP website (PPPL).
(I presume Qian will cover pretransp & FGM also, but I want
to emphasize GA's role as first user/tester of the service).
-- Success of TRANSP service
-- adopted by major US experimental programs.
-- on time for 2002 APS.
-- run production statistics.
-- Future directions
-- likely international customers for TRANSP NFC service.
-- developing between-shots capability.
-- TRANSP as MDSplus data source for GS2 service @ U. Maryland.
-- (long term) direct utilization of GS2 server for first
principles TRANSP predictive simulation.

TRANSP
- Grid-enabled MDSplus data server at DIII-D stores both input data and results
- PreTRANSP
* Prepare and load inputs into secured MDSplus server
* Work in concert with code management database
* Dispatches TRANSP onto the Fusion Grid
- Demonstration at TTF, Sherwood, APS and SC02
* Portable implementation allows TRANSP submission from a laptop using a phone line
- Grid-TRANSP used by DIII-D researcher s, results presented in APS invited talk
- Benefits to DIII-D research
* Grid-TRANSP centrally maintained, researchers always use the most up-to-date version
* TRANSP service cluster increases throughput
* Researchers donıt have to spend time on learning the non-physics related details of running a code, can concentrate on research
Fusion Grid Monitoring
- Functions
* Grid-wide code run monitoring
* Centralized record keeping
- Implementation
- Platform independent web interface

display walls to evaluate for remote collaborative visualization.
Resulted in a set of notes on what worked or not.
o Worked with PPPL to put up a prototype display in the NSTX control room.

This talk builds on all the previous talks and outlines the exciting
and valuable things the NFC can and should be doing not only over our
remaining 1.5 years but beyond the presently funded time frame. We need
to show excitement beyond with the fusion base program as a customore
as well as potential new customers in ITER and the FSP.
