An Interactive Java Profiler for the F2F Computing Framework

Vladimir Škarupelov

Agenda

• SIP Communicator• Java F2F Computing Framework• Profilers• Steps to be done

sip-comm

• Audio/video Internet phone and instant messenger

• Supported protocols:– SIP– Jabber– ICQ–MSN– others 

sip-comm

• OSGI architecture• Easily extensible by plug-ins• activate/deactivate feature• open-source

Java F2F Computing Framework

• Power share plug-in for sip-comm• On top of sip-comm• Sharing depends on– F2f implementation itself– Job implementation – friends/peers resources

Profilers

+– Profilers can provide information about application’s narrow places

– Extremely helpful in development– Can be used as monitoring

-– Significantly slows down the application

Profilers

• hprof• Eclipse TPTP project• NetBeans• Jprofiler• jmemprof• JIP• Profiler4J

• pure java• hooks the classloader• "on the fly" connection• Open source

Profiling made easy 

Next steps

• Set up F2F with the latest version of SC• Add Profiler4J plugin• Remote invoke of the profiler on a peer• Lazy profiler init• Look for another improvements
