New article How to Install and Use OpenCL for Calculations is published at mql5.com:
It has been over a year since MQL5 started providing native support for OpenCL. However not many users have seen the true value of using parallel computing in their Expert Advisors, indicators or scripts. This article serves to help you install and set up OpenCL on your computer so that you can try to use this technology in the MetaTrader 5 trading terminal.
What is OpenCL?
OpenCL is the open standard for parallel programming developed by the Khronos Group consortium in 2008. This standard allows you to develop applications that could be run in parallel on GPUs or CPUs with different architecture in a heterogeneous system.
In other words, OpenCL makes it possible to utilize all CPU cores or GPU's enormous computing capacity when calculating a task, thus reducing program execution time. Use of OpenCL is therefore very beneficial when dealing with tasks associated with laborious and resource consuming computations.
For example, speaking of MQL5, performance gain can be very rewarding when handling a certain script (indicator or Expert Advisor) that performs a complex and lengthy analysis of historical data by several symbols and time frames (it should be noted here that a MQL5 program that is intended to employ parallel execution should be written in a special way using OpenCL API).
