MOPS Analyses Axelrod Tim The Moving Object team completed find/linkTracklets scaling tests at various densities of solar system model, one set of scaling tests with half-density, and varying densities of "noise points", and initial tests of parallel subset track removal for massive data sets. The tests show that runtimes scale cubically with density of real solar system objects. This means that for most fields, full-density runtimes are reasonable, and after chi-squared probability filtering the volume of tracks output is manageable. After the filtering noise density has minimal impact on the number of tracks output or objects found; so the addition of noise increases runtimes but not enough to be a major concern at reasonable densities. We will continue to evaluate additional algorithms for the most dense fields. 20110520
Complete analysis of runs of FindTracklets/LinkTracklets? and OrbFit? driven by simulated DIASources 20081010 20110427 Axelrod Tim[20%],Myers Jonathan[75%] 75% 20110425
Estimate amount of CPU required for LSST MOPS 20101108 20110502 Axelrod Tim[20%],Myers Jonathan[75%] 75%* Completed find/linkTracklets scaling tests at various densities of solar system model and one set of scaling tests with half-density SSM and varying densities of "noise" points. Results show linkTracklets runtimes scale cubically with density of real SSM, but at full-density runtimes are reasonable and after chi squared probability filtering the volume of tracks output looks manageable. The addition of noise appears to significantly increase linkTracklets runtimes but not enough to be a major concern at reasonable densities; after the chi squared prob filtering noise density has minimal impact on the number of tracks output or objects found. 20110520
Prototype key algorithms in MOPS design 20101206 20110523 Axelrod Tim[20%],Myers Jonathan[75%] 50% Initial tests of parallel subset track removal for massive data sets completed at SDSC.

Update Mountain/Base? Network Design 20101022 20110422 Lambert Ron[20%] 50% At meetings with the Chilean national (REUNA) and international (AmLight?) research network institutions that will be providing the Base to Archive networks for LSST during operations, we created a plan to upgrade the bandwidth available on these links by 4 times on average, and 8 times peak, for a very modest change in total life cycle cost. This change would provide 10 Gbps daytime, 40 Gpbs nighttime, and 80 Gbps burst capacity and move approximately $15M from operations to construction. Not only does this permit a higher reliability of transfer in the current model, but also enables new operational models for data transfer and alert generation. 20110520
