Tài liệu 20 Terabytes a Night by Doug Rosenberg with Matt Stephens doc
... a night 21 summarizes the challenge facing Jeff and Tim very nicely: The LSST website The science archive will consist of 400,000 sixteen‐megapixel images per night (for 10 years), comprising 60 PB of pixel data. This enormous LSST data archive and object database enables a diverse multidisciplinary research program: astronomy & astrophysics; machine learning (data mining); exploratory data analysis; extremely large databases; scientific visualization; computational science & distributed computing; and inquiry‐based science education (using data in the classroom). Many possible scientific data mining use cases are anticipated with this database. The LSST scientific database will include: * Over 100 database tables * Image metadata consisting of 700 million rows * A source catalog with 3 trillion rows * An object catalog with 20 billion rows each with 200+ attributes * A moving object catalog with 10 million rows * A variable object catalog with 100 million rows * An alerts catalog. Alerts issued worldwide within 60 seconds. * Calibration, configuration, processing, and provenance metadata Sky Movies—Challenges of LSST Data Management The Data Management (DM) part of the LSST software is a beast of a project. LSST will deal with unprecedented data volumes. The telescope’s camera will produce a stream of individual images that are each 3.2 billion pixels, with a new image coming along every couple of minutes. In essence, the LSST sky survey will produce a 10 year “sky movie”. If you think of telescopes like LBT producing a series of snapshots of selected galaxies and other celestial objects, and survey telescopes such as Sloan producing a “sky map” 22 , then LSST’s data stream is more analogous to producing a 10 year, frame‐by‐frame video of the sky. LSST’s Use Cases Will Involve Accessing the Catalogs LSST’s mandate includes a wide distribution of science data. Virtually anyone who wants to will be able to access the LSST database. So parts of the LSST DM software will involve use cases and user interfaces for accessing the data produced by the telescope. Those data mining parts of the software will be designed using regular use‐case‐driven ICONIX Process, but they’re not the part of the software that we’re concerned with in this book. ... A Few More Thoughts About ICONIX Process for Algorithms as Used on LSST Modeling pipelines as activity diagrams involved not only “transmogrifying” the diagram from a use case diagram to an activity diagram, but also incorporating “Policy” as an actor which defined paths through the various pipeline stages. Although the LSST DM software will run without human intervention, various predefined Policies act as proxies for how a human user would guide the software. As it turned out on LSST, there were two parallel sets of image processing pipelines that differed only in the policies to guide them, so making the pipeline activity diagram “policy driven” immediately allowed us to cut the number of “pipeline use case diagrams” in half. This was an encouraging sign as an immediate simplification of the model resulted from the process tailoring we did. Modeling pipeline stages as high‐level algorithms meant replacing the “schizophrenic” algorithm‐ use case template of Inputs: Outputs: Basic Course: Alternate Courses: With an activity specification template more suited to algorithms, namely: Inputs: Outputs: Algorithm: Exceptions: Not surprisingly, writing algorithm descriptions as algorithms and not as scenarios made the model much easier to understand. This simple process modification went a long way towards addressing the lack of semantic consistency in the model. We used robustness diagrams to elaborate activities (is that legal?) 29 The “algorithm‐use cases” that had been written in Pasadena had been elaborated on robustness diagrams, and we made the non‐standard process enhancement to elaborate the pipeline stage activities with these robustness diagrams as well. Enterprise Architect was flexible enough to support this. Modeling Tip: Good modeling tools are flexible I’ve been bending the rules (and writing new ones) of software development processes for more than 20 years. One of the key attributes that I look for in a tool is flexibility. Over the years, I’ve found that I can make Enterprise Architect do almost anything. It helps me, but doesn’t get in my way. Keeping this elaboration of pipeline stage algorithms on robustness diagrams was important for a number of reasons, one of the primary reasons being that we wanted to maintain the decomposition into “controllers” (lower level algorithms) and “entities” (domain classes). Another important reason was that project estimation tools and techniques relied on the number of controllers within a given pipeline stage (and an estimate of level of effort for each controller) for cost and schedule estimation. ... a night 21 summarizes the challenge facing Jeff and Tim very nicely: The LSST website The science archive will consist of 400,000 sixteen‐megapixel images per night (for 10 years), comprising 60 PB of pixel data.
