Description

This Package contains a service ProfilerService and two analyzer modules StartProfilerAnalyzer and StopProfilerAnalyzer that allow to instrument only some portion of a cmsRun with performance measurument tools. At the moment only callgrind is supported. Extending it to other tools such as IgProf is easy.

Public interface

ProfilerService: provides a public interface mainly for the Start and Stop ProfilerAnalyzers. It can be used by other modules and services though...

Modules

StartProfilerAnalyzer: start profiler (callgrind) instrumentation
StopProfilerAnalyzer: stop profiler instrumentation

No set of parameters required

Services

ProfilerService

Parameter Set

untracked int32 firstEvent
untracked int32 lastEvent
untracked vstring paths

Unit tests and examples

testPerfToolsCallgrind: a unit test of public and internal API of the ProfilerService
test.cfg: integration test of Service and Analyzers

Status and planned development

Service and Analyzer Completed
One may need to add some addional control in case a StopAnalyzer is not called: for the time being the instrumentation is forced to stop at the end of each event.
The Service may be extended to tools other than callgrind such as IgProf
