On Processing Extreme Data
Extreme Data is an incarnation of Big Data concept distinguished by the massive amounts of data that must be queried, communicated and analyzed in near real-time by using a very large number of memory or storage elements and exascale computing systems. Immediate examples are the scientific data produced at a rate of hundreds of gigabits-per-second that must be stored, filtered and analyzed, the...
متن کاملActiveSpaces: Exploring dynamic code deployment for extreme scale data processing
Managing the large volumes of data produced by emerging scientific and engineering simulations running on leadership-class resources has become a critical challenge. The data have to be extracted off the computing nodes and transported to consumer nodes so that it can be processed, analyzed, visualized, archived, and so on. Several recent research efforts have addressed data-related challenges ...
متن کاملQuality Control Methods in Accelerometer Data Processing: Identifying Extreme Counts
BACKGROUND Accelerometers are designed to measure plausible human activity, however extremely high count values (EHCV) have been recorded in large-scale studies. Using population data, we develop methodological principles for establishing an EHCV threshold, propose a threshold to define EHCV in the ActiGraph GT1M, determine occurrences of EHCV in a large-scale study, identify device-specific er...
متن کاملIn situ data processing for extreme scale computing
The DOE leadership facilities were established in 2004 to provide scientist capability computing for high-profile science. Since it’s inception, the systems went from 14 TF to 1.8 PF, an increase of 100 in 5 years, and will increase by another factor of 100 in 5 more years. This growth, along with user policies, which enable scientist to run at, scale for long periods of time, have allowed scie...
متن کاملExtreme Value Statistics for Novelty Detection in Biomedical Data Processing
Extreme value theory (EVT) is a branch of statistics which concerns the distributions of data of unusually low or high value i.e. in the tails of some distribution. These extremal points are important in many applications as they represent the outlying regions of normal events against which we may wish to define novel events. The use of such novelty detection approaches is useful for analysis o...
