Win $20,000!

Sun has announced a Community Innovation Awards Programme - basically a $1M of prize money available for various Sun-sponsored open source projects. There is an OpenSPARC programme, and the one that catches my eye is $20k for:

vi. Best Adaptation of a single-thread application to a multi-thread CMT (Chip Multi Threaded) environment

My guess is that they will expect more than the use of -xautopar -xreduction or a few OpenMP directives :) If I were allowed to enter (unfortunately Sun Employees are not) I'd be looking to exploit the features of the T1 or T2:

  • The threads can synchronise at the L2 cache level - so synchronisation costs are low
  • Memory latency is low

The upshot of this should be that it is possible to parallelise applications which traditionally have not been parallelisable because of synchronisation costs.

Funnily enough this is an area that I'm currently working in, and I do hope to have a paper accepted for the MultiExpo.

Open source application tuning

My group has started a page on the Sun wiki detailing the steps necessary to compile and build a number of open source applications. The page also contains links to useful destinations in the compiler documentation. Feel free to suggest ideas for applications that we should cover there - I can't guaranty that we'll manage to look at them, but I'd love to know what's important to you!
