PerformanceDebugging

System requirements:

• Window/Linux Operating System
• JAVA Development Kit 8
• Eclipse (Juno or latest)

What you need to do to run this

1. Import the project in Eclipse
2. set your input in the stacktrace.txt file
3. run the Main.java file
4. you will find the output in the output.txt file

Input file format

• number of functions number of stacktraces
• index of the function name of the function //for all the functions
• space separated callstack of the stacktrace //for all the stacktraces

The example is here

Output file format

• frequent subsequence (indexes of the functions, -1 as the end of the subsequence)
• #SUP: number of callstacks contains this subsequence
• #SID: indices list of the callstacks contains this subsequence

The example is here

Base project

StackMine has been applied in performancce debugging activities at a Microsoft team for performance analysis, espacially for a large number of executive traces by calculating their cost.

My project

In my project i calculated the frequency of the sequences and cluster them. Then calculated their cost as the base project did.

I didn't extended the existing project.
