Hi, are there any projects that can dedicate all processor cores to a single task?

Perhaps it would be an idea to keep this updated for others who may be interested?

AQUA@Home is the only project thus far with multithreading capability.

As long as the memory footprint of the application is small, involving multiple processors will reduce performance. The owner of the machine should instead start multiple jobs.

Do you mean this as a rule???????

A 32-thread application could work on a say half meg memory block with no (0) contention. Depends just on the algorithm. It may spend 1/2 CPU time in locking, or no at all.
