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.

Innovating with the OpenSPARC CPU Expert Exchange next week
The Expert Exchange on OpenSPARC is next Wednesday (31st January) at 10am PST. The URL for registration is here. The format is that a number of folks will get together and answer any (relevant ;) submitted questions. The questions and answers will appear as fast as we can type them, and a transcript will be available for those folks who were unable to make the live event. I'll be attending to field questions on the Cool Tools.
