The facility employs special purpose high-performance computers, such as the Gravity Pipeline Engine (GRAPE), a new Beowulf cluster (128 processors, 128G RAM, 2 TB RAID disk), and a system using Graphics Processing Units to achieve computational speeds of up to a trillion floating point operations per second. The Joseph R. Lynch Observatory houses a 16-inch Mead Schmidt-Cassegrain telescope equipped with SBIG CCD camera. Drexel faculty and students actively analyze data from the Sloan Digital Survey, which operates a 2.5-m telescope at Apache Point, New Mexico, and the Large Synoptic Survey Telescope to be built in Chile (2020).
