Hi there, I was playing around with AI Generate today and on my algo testing machine with high performance components (Ryzen 9 3900X 24 threads, 32GB DDR4 4000 RAM, 2TB NVME), NT8 is only using four cores and not even fully. Any idea why? I am of course using latest NT8, lifetime license and 64 bit edition.

Hello Oracletrades, thanks for your question.
Please try running an optimization on the SampleMACrossover strategy, do you get all cores used there? All of the cores I have (4) are being used when I do an AI generate and optimization. So we might be looking at a case where AI generate uses only 4 cores whereas optimization will use all of them. If we get that kind of result, I will need to ask my supervisor on what to do.
I look forward to hearing from you.Chris L.NinjaTrader Customer ServiceComment

Thanks for the reply. On optimization, NT does seem to use all threads, my point was about the AI Generate tool.

Hi Oracletrades, thanks for your reply.
I am getting 4 cores used on an AI generate backtest. I don't have a machine with more than 4 cores to test on so I am not sure if it's locked to 4 cores somehow or something else. I will let our development team know to look into this issue.
Kind regards.Chris L.NinjaTrader Customer ServiceComment

Hello Oracletrades, thanks for your patience.
We tested with a Ryzen CPU and we are getting all cores used. In your screen shot it looks like the rest of the cores are used, but not all the way to 100%. If that is the case then it would be the operating system handling that part, since we confirmed the design can use every core of the machine. When a C# application is made with multithreading, it doesn't need to handle the core usage, it simply needs to spawn a new thread and the operating system will determine which core that thread is ran on.
