Fault-Tolerant Parallel-Processing Astronomical Image-Analysis Tools
|
|
|
| This proposal describes a three-year research plan to develop and implement several new fault-tolerant parallel-processing astronomical image-analysis tools suitable for the analysis of stellar imaging data from the current and future NASA astrophysical missions. One such tool will be a fault-tolerant version of the PI's CCD Circular Aperture Photometry (CCDCAP) code for the Hubble Space Telescope's Advanced Camera for Surveys (ACS) instrument. The PI will enhance his existing AISR-funded QLWFPC2 quick-look photometry data-mining code and the MATPHOT precision PSF-fitting CCD stellar photometry and astrometry code by making them fault tolerant as well as faster and more robust. These data-analysis software tools will be written with the goal of enhancing the scientific return of the the HST and the Spitzer Space Telescope missions as well as future planned missions such as the James Webb Space Telescope. Efforts will be made to implement some of the data-mining tools at NASA data archives or mirror sites for HST and SST in order to provide an interactive and more scientifically useful user experience while possibly making the serving of archival imaging data more efficient. The fault tolerance of these applications will be achieved by working closely with the LAM/MPI 10.0 team (at the Los Alamos National Laboratory and Indiana University) to implement state-of-the-art fault-tolerant techniques into parallel-processing applications suitable for space-based scientific analysis with a cluster of COTS-based fault-tolerant computers. The LAM/MPI 10.0 team will test these space science applications inside a software test environment for fault tolerance. The PI will provide advice to the LAM/MPI 10.0 team on application implementation issues and the software needs of space science image-analysis applications. The PI will attend the quarterly LAM/MPI 10.0 meetings. Expert optical and infrared astronomers will test the software, review the documentation and make suggestions for improvements. The project software products will be released to the general space-science and computing-science communities by placing them in the AISRP Code Archive Library. Project highlights and annual reports will be posted at the main AISR website. Additional project related material will be posted on websites dedicated to this project on the web server of the National Optical Astronomy Observatory. |
