Description

This is also a proposal for a GSoC project.

Below are comments coming from Richard Jones:

  • The GCspy drivers have lagged behind JikesRVM development
  • Richard has drivers for GenCopy, GenMS etc but for old versions
  • It would be nice to have drivers for all the collectors in 2.9
  • There's a new version of GCspy that needs integrating (see Cheadle et al, ISMM06); this also has support
    for high frequency events which might be interesting.
  • Richard has some ideas for enhancements and using GCspy to control collector etc more in an experimental setting.

It would also be interesting to integrate the visualization with tuning fork:

Hi all,
my Name is Thomas Nawrath, i am studying Computer Science at the University of Applied Sciences Hamburg in Germany. I am about to write my Bachelor Thesis in Computer Science and I would like to do this by implementing a driver for GCspy and write about the scientific issues covered in the implementation.
Therefore, I would like to apply for assignation of the issue rvm-388.
Also mentioned here: http://jikesrvm.org/Project+Proposals+2008

There are some strict border conditions however:

  • I have to finish the Project until 01.08.2009.
  • I can contribute 60 fulltime workdays for the implementation until the project has to be finished.

I am also looking for a mentor. If you think you are the right person to mentor me or know the contact data to the right person, please let me know.

Greetings,
Thomas

Hi Thomas,

I suggest you contact the original proposed mentor Richard Jones (R.E.Jones@kent.ac.uk) about this opportunity. I am one of Richards PhD students who originally applied for GSoC funding to tackle this problem. Unfortunately the funding from GSoC is limited and was directed towards more pressing JikesRVM issues.

Since the original GSoC application Richard had a summer intern work on the project - some progress was made but I am not sure of the current working state of the project. I know that the current GCspy C server was dropped in favour of using the GCsp C++ server. To stand a chance at this being a successful project for your Thesis you would need to be familiar with C++, Java and have some knowledge of Garbage Collection.

If you have further questions please don't hesitate to ask.

Kind regards
Laurence
