| 2-Micron All Sky Survey (2MASS) digital images of the sky in infrared, as stored in NPACI's HPSS at SDSC, have been combined to produce a 2MASS Gallery image mosaic of the Cat's Paw Nebula, NGC 6334. Having online access to such large amounts of data will enable unprecedented scientific research to be carried out. Red, green, and blue color values in the image represent intensities in the J (1.2 µm), H (1.6µm), and Ks (2.2 µm) infrared wavelength bands. The full sized (2580 x 2742, 5.6 MB) image mosaic by S. Van Dyk of IPAC/Caltech covers an area of the sky 42 arc minutes on a side. See http://www.ipac.caltech.edu/2mass/gallery/ngc6334atlas.jpg. 2MASS is a joint project of the University of Massachusetts and IPAC/Caltech funded by NASA and NSF. | |
| HPSS at the San Diego Supercomputer Center Reason for HPSS at SDSC Computational scientists at the San Diego Supercomputer Center (SDSC) and the National Partnership for Advanced Computational Infrastructure (NPACI) require huge amounts of storage space for the growing data sets they generate from experiments, computer simulations, and field observations. The HPSS installation at SDSC is a large, centralized file management and storage system that serves as a permanent file space for users. HPSS software is designed to move very large data objects between high-performance computers, disks, and tape libraries. Size of SDSC’s HPSS System SDSC manages one of the world's largest production installations of HPSS. Currently storing more than 280 TB of data in almost 15 million files, data is added at an average rate of 8 TB a month. Digital Sky Project’s 2-Micron All Sky Survey With modern sensors, astronomers are generating increasingly large data sets. For example, as part of the Digital Sky Project, the 2-Micron All Sky Survey (2MASS) has already stored more than 10 TB of data in HPSS at SDSC. Eventually, the 2MASS Image Retrieval Service from Caltech's Infrared Processing and Analysis Center (IPAC) and SDSC will give scientists access to the entire infrared sky in 4 million high-resolution digital images. Having access to such large amounts of data will enable unprecedented scientific research to be carried out. |
