The SMP Client runs 4 threads?

[Vengance_01]

I am trying out the SMP to see how it works and if its any better than the regular client and was wondering why does it create 4 threads using about 25% resources only?

I believe that is because it is designed for quads, but it runs just fine on dual-core systems.

I believe it was initially planned for 2 dual cores or 4 single cores instead of honkin powerful cdc boxes etc.

Damn you Ben!

Too fast for me!

Hey Dorian I'll be in the Zim contest and the Chimp challenge. I'll be down to 660ppd... use the time wisely :p

Im getting tired of waiting on you.:burn:

I would think it would act similar to GCC in that it would create # of cores + 1 threads for optimal performance.

[pscout]

The # of threads is set at 4 with the current smp clients. There has been dicussion at FC about changing that but I haven't read anything about when/what it will change to.

There is some differentiation in the wu's that are assigned to quad cores in linux ... the 1440 pt ones only go to quads afaik. Other wus will also get assigned to the quads. But they are all still running the same 4 threads/cores as the client would run on a DC rig (or even on a HT p4).
