Nehalem 8threads running Toga 1.4.2JD-8cpu

Post by jpqy »

Here you can see TogaII 1.4.2JD-8cpu running on the new Nehalem at 3Ghz!stock speed.

I let him just calculate from the begin position...and compare it with your computer how many nodes you get!
With my computer a Q6600 at 3.2Ghz i have 4.4Million/nodes and the Nehalem gives 5.8Million/nodes!! So it will be a nice speed gain again!

So e4 is the best first move, and black should defend with the Petroff! Good to know... :)

Nice stats JP! At least I could see a Toga stats report on an 8-core.

But I would like to ask the experts here about something I noticed, say, based on the nehalem14.jpg (and the other Toga mp stats for that matter).

If I compute using the last node-count and time usage, the average nps would be ~732,021nps. If I multiply it with 8, then we get around 5.8M nps. So, does it mean my initilal computed value is for every core?

I only asked as other MP engines doesn't show this discrepancy. Thanks.
