| Follow Geoffery Fox's(NPAC) flexible and scalable three tier architecture |
| NPAC provides the "glue" for this architecture by setting up the middle tier server. This middle ware will handle multiple protocols, such as HTTP, RMI, CORBA etc. We will be concerned with the (browser based) front end to middle tier communication, as well as the middle tier to the HPC backend interaction. Interact closely with the NPAC team to develop interfaces for these communications. |
| Front end middle tier interaction will be built on excellent CCM work. May use Java based technology to implement. Concentrate on developing standard interfaces to communicate between the middle ware and the back end. Extensive effort involving the CEA community. |

| Continually interact with NPAC team to insure we follow the proposed architecture. We are flexible as far as the implementation details are concerned. (impartial to Java/RMI, CORBA/C++/Java, other standards) |
| What is important are the standardized interfaces we will develop in collaboration with the NPAC team. These standard interfaces will enable us to "plug" various CEA High Performance codes to the middle ware. |
| We will work closely with Nichols Research, and work as a team with them. We will make sure that Nichols research remains in the loop, and is comfortable with what we are doing. We will continue to offer support and advice to Nichols Research in the future. |

| A general-purpose radar signature prediction code and environment for calculating high frequency electromagnetic scattering from complex objects described by several different CAD representations. XPATCH has been developed by DEMACO in Champaign IL under the joint tri-Service sponsorship of Wright Lab at WPAFB OH, Phillips Lab at Kirtland AFB, NM, the Army Research Lab at Ft. Belvoir VA, and the Naval Air Warfare Center at Pt. Mugu Cal. |
| All documentation is being rewritten in HTML and efforts are underway to consider rewriting the interface to directly interface with the CEA PSE. |

| A parallel time domain electromagnetic code for modeling Three-Dimensional scattering targets and microwave circuits. The components of this code include both grid manipulation packages computational solvers, and visualization technology. PFDTD is being developed by John Nehrbass in support of the DOD HPCMP for users at AMSRL-SE-RE sensors directorate, the MURRI projects on De-mining, AFRL/SND RF Front End research and development |

| Very few problems can be solved exactly when studying electromagnetic problems (i.e. Sphere). For this reason accurate real life benchmark data is vital to insuring accuracy. This benchmark suite would include measurements and prediction from such DOD targets as Antennas, simplified B2, ZSU23-4 tank, and classified data. The ability to provide this data to a controlled group is vital to the war-fighter efforts. |
