摘要： Techniques for profile clustering for homogenous instance analysis are described herein. An aspect includes collecting for each of a plurality of homogenous instances in a cloud computing environment, respective profiling information, the profiling information comprising counter data. Another aspect includes identifying a code unit for analysis. Another aspect includes aggregating counters corresponding to the code unit for each of the plurality of homogenous instances from the respective profiling information. Another aspect includes determining a cluster comprising a subset of the plurality of homogenous instances based on the aggregated counters.

摘要： A computer-implemented method, a computer system, and a computer program product for trajectory similarity search is provided. The present invention may include, in response to receiving, by one or more processors, a search request for at least one trajectory similar to a query trajectory, determining, by one or more processors, a respective similarity between a query trajectory and a plurality of trajectories by calculating, in a synchronized way, a spatial distance measure and a time difference measure between the query trajectory and the plurality of trajectories. The present invention may further include, identifying, by one or more processors, the at least one trajectory from the plurality of trajectories based on the respective similarity between the query trajectory and the plurality of trajectories.

摘要： In one embodiment of the present disclosure, an original graph including nodes is obtained. The nodes of the original graph are reordered to generate a reordered graph. Non-zero elements in an adjacency matrix for the reordered graph are clustered as compared with an adjacency matrix for the original graph. The adjacency matrix for the reordered graph is encoded with integers. The integers correspond to non-empty blocks in the adjacency matrix for the reordered graph.

摘要： A computer-implemented method for proactive change verification is provided. Aspects include analyzing runtime execution characteristics from a plurality of base activity metrics and a plurality of experimental activity metrics and creating a plurality of activity pairs wherein each activity pair comprises a base activity metric and its corresponding experimental activity metric. Aspects also include identifying significant activity pairs from the plurality of activity pairs wherein the experimental activity significantly deviates from its corresponding base activity and classifying significant activity pairs by deviation type. Aspects further include sorting activity pairs by their impact and removing activity pairs that have an impact of less than a threshold amount, wherein the threshold amount is based on the deviation type. Aspects also include correlating interacting impactful activity pairs temporally and prioritizing impactful activity pairs using experimental activity deviations and displaying the impactful activity pairs.

摘要： A method for control flow analysis according to an embodiment of the present invention includes: acquiring an original function call tree of a program, wherein nodes of the original function call tree represent functions and a parent/child relation between the nodes represents a calling relation; generating a corresponding function dominator tree from the calling relation, wherein nodes of the function dominator tree represent the functions and a parent/child relation between the nodes represents a dominator relation, wherein a first function dominates a second function if all the invocations to the second function are originated by the first function; and simplifying the original function call tree according to the function dominator tree so as to obtain a simplified function call tree. According to an embodiment of the present invention, the function call tree for control flow analysis can be simplified.
