Abstract: In a computing device that implements a data object classification tool, a method for classifying data may include detecting change in spatial coordinates for each of at least two of a set of data objects within a canvas space. Each of the data objects may be associated with a vector of features. A rule set may be generated based on the vector of features associated with each of the at least two data objects. The rule set may use feature(s) that explain the changed spatial coordinates. The data objects may be selectively rearranged within the canvas space by applying the generated rule set to any remaining data objects among the set of data objects so as to assign spatial coordinates to the remaining objects. For each of the data objects, the spatial coordinates may be stored as new semantic feature(s) within the vector of features for that data object.

Abstract: A computer-executable method, system, and computer program product of managing I/O received within a Lustre file system, the computer-executable method, system, and computer program product comprising: receiving a data I/O request, wherein the data I/O request relates to data stored within the Lustre file system; processing the data I/O request in a journal stored on a fast data storage device within the Lustre file system; analyzing the journal to make a determination related to the data I/O request; and responding to the data I/O request.
