1. A method comprising:
- analyzing the operation of a computer application, the computer application comprising a first program thread and a second program thread;
recording overhead for the first program thread and the second program thread;
observing an event comprising the transfer of a signal from the second program thread to the first program thread; and
adjusting the overhead for the first program thread if the first program thread waits a time period before receiving the signal from the second program thread.

Abstract
A method and apparatus for adaptive and dynamic filtering of threaded programs. An embodiment of a method comprises analyzing the operation of a computer program, the computer program comprising a plurality of program threads; tracking overhead for the computer program; observing program events for the computer program; rationing overhead between program threads in inter-thread program events; and filtering program events based on a dynamic threshold.

11. A performance analyzer comprising:
-
an adaptive filter for a multithreaded program, the adaptive filter to determine the rationing of overhead between a plurality of program threads in program events; and
a dynamic filter for the multithreaded program, the dynamic filter to modify a threshold for collection of data based on the performance of the program. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A system comprising:
-
a dynamic memory to store a multithreaded program, the program comprising a first program thread and a second program thread;
a processor to run the multithreaded program; and
an analysis tool to analyze the performance of the multithreaded program as run by the processor, the analysis tool comprising a first component to track overhead for program threads and a second component to determine which program events are to be observed by the analysis tool. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27)
