GRAPHICAL LOCK ANALYSIS

摘要

A system is described for identifying key lock contention issues in computing devices. A computing device is executed and lock contention information relating to operations during execution of the computing device is recorded. The data is parsed and analyzed to determine blocking relationships between operations due to lock contention. Algorithms are implemented to analyze dependencies between operations based on the data and to identify key areas of optimization for performance improvement. Algorithms can be based on the Hyperlink-Induced Topic Search algorithm or the PageRank algorithm.

1. A method comprising:
executing a computing device for a predetermined time interval and recording data related to the execution of the computing device into a log; analyzing the data recorded into the log to identify blocking relationships between processes executing on the computing device, wherein blocking relationships comprise lock contention information related to a first process being blocked by a second process due to the first process being unable to acquire a lock on an object because the second process is holding the lock on the object; plotting the data into a graph data structure comprising:
a plurality of nodes, each node representing one of the processes executing on the computing device; andlinks between the nodes that indicate the blocking relationships between the processes; and displaying a visual representation of the graph.
