+1 on Ninja and multi cores (I've tested on 8 core Mac Pro, similar result). However can you elaborate on your experience with SSD?
@Big Mike - I am sorry for hacking your thread with above question.
Srry, but this is impossible. As backtesting ivovles multiple instances of the strategy running at the same time - and they are independant ---- I fail totally to see how that can be the fault of the strategy. Any explanation welcome - I am quite pissed on backtests taking 7 hours or so.
Well it's been a long time since I used NT, but I will try to remember and provide details.
I scored everything using "iterations per second", so I could see one strategy's performance vs another in terms of optimization time.
I absolutely saw differences ranging in 100's of percent increase from one strategy to another.
You might just take the simplest of simple strategies (like a simple moving average cross), and see if your CPU utilization is different.
I sped my strategies up by using internal functions that returned double's as much as possible, instead of calling external indicators and maintaining dozen's of DataSeries. I also built-in as many of the indicators directly into the strategy as possible instead of calling them, for the same reason.
Anyway, I don't want to get off-topic as strategy optimization deserves its own thread.
I mainly wanted to know if anyone had run NT7 with more than 16 cores with favorable results. For example, I know with MultiCharts each additional core proportionally increases the memory requirements, so running 8 cores is double the memory requirements of 4 cores, based on my understanding. I wanted to see if NT was the same.
Let me say first that I'm new to NT and futures.io (formerly BMT). Still in the learning process. But I'm running on on a EVGA SR-2 with dual Intel X5690s. 12 cores and 24 hyper threads. So far, I've been disappointed in the core utilization and parallel capabilities of NT. My workstation is barely pushed in CPU. I can do any test you'd suggest as I'd like to have better parallel performance.
My system config is EVGA SR-2, 2 x5690 CPUs, 48 GB ram, 4 TB SSD in Raid 5, and AMD V7900 graphics. Overkill but its the type of hardware I'm used to working on. I'm planning to use the existing workstation with VMs once I have my strategies worked out.
