Can multiprocessors improve the speed of NT7 strategy optimization?
By the way, I tested 16 threads Amazon Cloud last night, the speed is a little bit better than 32 threads cloud, 4 hour compare to 4 hour 20 minute. I then tested 8 threads Cloud, it'd be much slower. So threads do help but seems above 16 or maybe 20, then it won't help much anymore.
No, still cloud. I just scale down 32 threads to 16 threads then to 8 threads. I figured if 8 threads runs the same as 32 threads, then treads don't help much. The final results are threads do help, just above 16 or maybe 20, then it won't improve much. So this would help on what kind of machine to buy, basically a 8 core processor is enough to run NT7.
If turn off hyperthreading helps, then probably a 2*8 core processors would be the best bet.
So long as you know for sure that you are the only one using that particular machine, otherwise the test counts for nothing. Clouds offer lots of 'flexibility' for the vendors as well as for their users.
I know, thanks. That's why I want to test on a physical machine now. but seems the IT guy cannot install Windows 2008 on the server, I've been waiting couple of days now. He's my friend, cannot blame him, so if he cannot install, then I'll have no way to test on real hardware anymore.
Oh, I sure hope so. But the question is when they release NT8, it's been millions of years.
By the way, I tested 2x12 threads E5 2640 real hardware, it's first generation E5, so the speed is much much slower, took 11 hours for the 5 hours i7 3930K job. It ran on all 24 threads 90% though.
