Here's what you can do with OpenCL directly in MetaTrader 5 without any DLLs - page 7

[Alexander Kuznetsov]

When trying to run the script, at first it went like this:

NN      0       21:04:58.552    Scripts script Seascape (EURUSD,H1) loaded successfully
MG      0       21:04:59.052    Terminal        OpenCL not found, install the latest OpenCL driver for better performance
PE      0       21:04:59.052    Scripts script Seascape (EURUSD,H1) removed

and then from http://www.nvidia.ru/Download/index.aspx?lang=ru

the latest card drivers were downloaded.

and the log messages are the same as above, when trying to run the script.

then Intel® SDK for OpenCL™ Applications for Windows* 2016 was downloaded from the website

http://registrationcenter-download.intel.com/akdlm/irc_nas/vcp/11058/intel_sdk_for_opencl_setup_6.3.0.1904.exe

at next new attempt to run the script, the following message will appear in the log:

RM      0       17:14:22.070    Scripts script Seascape (EURUSD,H1) loaded successfully
CQ      0       17:14:22.991    OpenCL  Device #0: CPU Intel(R) Corporation Intel(R) Core(TM)2 Duo CPU E6550 @ 2.33 GHz with OpenCL 2.1 (2 units, 2330 MHz, 4094 Mb, version 6.3.0.1904)
EP      0       17:14:23.661    Scripts script Seascape (EURUSD,H1) removed

well, who knows what's wrong?

it can't get this openCL* to work

You have, in the list of OpenCL devices, no video adapters!

Change the script code, instead of

   if((cl_ctx=CLContextCreate())==INVALID_HANDLE)

try the following line

   if((cl_ctx=CLContextCreate(CL_USE_ANY))==INVALID_HANDLE)

Compile the script

[Aleksey Vyazmikin]

Are there any limits to computing on the CPU and GPU?

[Andrey Dik]

-Aleks-:
Are there any limitations for calculations on CPU and GPU?

As a rule, the limitation is memory, both for GPU and CPU.

But one thing is clear - the code for the CPU is less demanding to optimize than for the GPU, it often happens that on the CPU smoothly works that on the GPU can not even run or quickly terminates with an error or crash of the video driver.

If this is the case, is it possible to use the GPU to calculate indicators and run the Expert Advisor on the CPU?

[prostotrader]

Dr.Trader:

OpenCL is very good, you can train neural networks very quickly with this technology, hundreds (thousands) of times faster than on an ordinary processor.

This can be corrected as follows: find these lines in the script -

                    "   uint b=(uint)(res[2]*255);\r\n"
                    "   uint g=(uint)(res[1]*255);\r\n"
                    "   uint r=(uint)(res[0]*255);\r\n"

and replace them with -

                    "   uint b=(uint)(res.z*255);\r\n"
                    "   uint g=(uint)(res.y*255);\r\n"
                    "   uint r=(uint)(res.x*255);\r\n"

Thank you!

It did work, but the "sky" has ripples in it.

It was clear to me, as a non-programmer, from the comments that this was not for the masses. But it was still interesting to read. Tell me, should I expect a wave of new ideas in the form of indicators and experts? Or is it just a toy for the elite?
