I don't know what you are talking about.TJ claims that MC uses all available cores within one CPU for normal charting and MC uses all available cores within all available CPUs for charting.
Marina is always right.However you claimed once that:THE QUESTION:Multiple cores are used to calculate indicators in parallel.
With multiple screens when large areas of the screen have to be updated those cores won't be used.
Who is right: you or TJ?

Hi TJ,you specifically say "Normal charting".
I didn't say anything of such.
What are you referring to that is normal?
what is the other thing that you refer to as charting, but not "normal"?
what is the conflict between what i said and what marina said???
This is a great example of GPU computational power.Look how these guys (Russian programmers) managed to create software that uses GPUs to crack passwords 50x faster than traditional password recovery methods that only use the computer’s main CPU.

8800 gt is 4 x faster than Q6600.
This topic is reminiscent of "The swan, a cancer and a pike" by Krylov. Everybody is going their own way. Tresor and me are trying to bring your attention to a technology that is going to change the rules of the game. We talking about accessing the tremendous power locked in the gaming graphics cards for strategy testing and optimization.Hi guys,
Before giving you any recommendations, we need to know what exactly it is that you are doing.
I think you have misunderstood the difference between calculating indicators/studies, and drawing the actual image on the screen.Hi TJ,you specifically say "Normal charting".
I didn't say anything of such.
What are you referring to that is normal?
what is the other thing that you refer to as charting, but not "normal"?

Normal charting = ploting bars (just price action).
I asked, you confirmed with ''I am using a Quad-Core, and I can tell you YES... MC uses all 4 cores. '' and with ''yes, all CPU, all cores''.
The conflict is with ''cores won't be used''. The ''cores'' are explained in the thread in which Marina posted here message once. This message was posted some time ago, so it maybe the case that the in the current MC ''those cores'' will work. I just want to clarify.
Let's give Marina a chance to answer.

Hi TJ,I think you have misunderstood the difference between calculating indicators/studies, and drawing the actual image on the screen.
drawing image on the screen is a house keeping process, therefore only one core is used.
the computer doesn't care what is normal to you.Hi TJ,I think you have misunderstood the difference between calculating indicators/studies, and drawing the actual image on the screen.
drawing image on the screen is a house keeping process, therefore only one core is used.
Please stay assured, I know the difference between drawing charts (something what I called ''normal charting'') and calculating studies applied to these charts.
The studies' calculation and other processes will be discussed in further questions. All I want to know now is how many cores are used to draw charts of price action. I apologise for confusion that I created with the unscientific term ''normal charting''. I should have been more precise.
Thank you for clarification.
Get yourself a Mac pro:In a short time from now I will be buying my professional trading rig that will consist of:
(i) 4 monitors (2560 x 1600 resolution each), and
(ii) a desktop (workstation).

Tresor,P.S. Marina, can you have a look at the previous post and anwser please?
From what I understand, a member of AB community speeded up AB backtesting x200 times using CUDA on his old graphics card.GPU computations in AB...

Hi Marina,Hi Tresor,
If you run multiple instances of MultiCharts, there will be no situation when you have one core 100% loaded and hardly coping while other cores remain idle. In the situation you are describing, MultiCharts will be using other available cores as well.
Regards.
OK, for the purpose of building the trading rig I will assume that only 1 core will be used. I will go for one highly clocked CPU to mitigate a potential risk of bottleneck when plotting charts.It depends on overall system load.
Another VERY important part is a fast video card, that's what draws the charts, so the faster the better.
Unless the software is specifically written to take advantage of the graphics (eg. OpenGL, DX10),
most of the graphics are CPU bound and handled only by the CPU.
My previous understanding of MC was:Assuming that graphics in MC are CPU bound (as opposed to GPU bound); does it mean that whether I select high end quality or low end quality graphics cards (supporting the desired resolution), such a selection would make no difference in quality / speed of the charts on my monitors
OK, so it is clear that only one core will be used to display the candles of 4 charts in one workspace.In your setup, with no indicators applied, 1 core will be used for working with all those workspaces and charts.
Yes, more than one core will be utilized in this case. MC uses mulitiple cores for studies (but not for price candles)Just to be complete, if you have one workspace with 4 charts and one indicator in each chart, will that use more than one core?
Yes.Does the presence of indicators utilize more cores?
I am still not sure about this. But Marina wrote:Or is having multiple instances of MultiCharts the way to use more cores?
