OpenCL: internal implementation tests in MQL5 - page 38

New comment
joo:

The double-boned GPUs have arrived. Very interesting. What's the CPU?

Run the script in the attachment.

One OpenCL task will run on one device only (limitation of the terminal due to the OpenCL curve when paralleling to both heads).
But for different contexts, the terminal will distribute tasks across devices.

Very good. You can split the overall task (if there is such a possibility in the algorithm) into different devices (use all CPUs and all GPU devices).
mql5: I could be wrong about it working on the CPU.
Where can you find out exactly, Ilyas?
The current implementation of OpenCL has no GPU/CPU priority and the main factor is the number of units in the device, while you have two units on both GPU and CPU, so you get first come, first served.
Let's wait for the next build where the OpenCL functionality will be improved.

Thanks for the info!

^^^ how would you like to test?

Run five or six fractals of mandelbrot in different windows (take it from the first page of this thread).

Report back with results!

Let's wait for the next build, ...........

Already sat by the window... :)

What's new planned?

MetaDriver:

Run five or six mandelbrot fractals in different windows (take the mona on the first page of the branch).

Report the results!

Running 10 fractals, one core is 100% loaded.

Second core is still at 0 load.
