Abstract:
Over the next few years there are two boundary conditions that should constrain computer systems architecture: commodity components and applications performance. Yet, these two seem strangely disconnected. Perhaps we need some human optimization, as opposed to repeated use of Moore’s Law. Our panelists have been given a set of standard components that are on announced vendor roadmaps. They also each get to make one mystery component of no more complexity than a commercially available FPGA. The applications are HPL for linear algebra, Map-Reduce for databases, and a sequence matching algorithm for biology. The panelists have 10 minutes to disclose their systems architecture and mystery component, and estimate performance for the three applications at 1MW of power.

Abstract: By cross matching blue objects from SDSS with GALEX and the astrometric catalogues USNO-B1.0, GSC2.3 and CMC14, 64 new dwarf nova candidates with one or more observed outbursts have been identified. 14 of these systems are confirmed as cataclysmic variables through existing and follow-up spectroscopy. A study of the amplitude distribution and an estimate of the outburst frequency of these new dwarf novae and those discovered by the Catalina Real-time Transient Survey (CRTS) indicates that besides systems that are faint because they are farther away, there also exists a population of intrinsically faint dwarf novae with rare outbursts.
