Hi all, I know seti@home computes 1 work unit per core, My PC is taking about 4-5 hours for a workunit per core.

Is there any way for 1 work unit to be worked on by all cores for faster compute times? or Is this more of a feature request?

I searched preferances and settings but cant find anything. Thanks in advance for your help.

This cannot currently be done. What you are asking for essentially is called multi-threading, and it was investigated back when Intel's HyperThreading Technology was new (2001/2002 timeframe). Last I recall, due to the context switching to verify each core's cache is kept coherent, it actually slowed down processing due to this overhead.

I do know that the third-party developers whom call themselves the Lunatics have been looking at multi-threading for a while now. It seems the general consensus is that GPU crunching is far more efficient and cost effective from a cost per watt perspective, so most of the focus remains in optimizing code in this area.
