What should be added for additional support of universal mathematical calculations in MQL5 and MQL5 Cloud Network?
Hence the question - what other features should be enabled to improve the calculation network capabilities?

This has been discussed many times - it is architecturally impossible because of the way Windows drivers work. As long as the calculation functions are a protected part of the video drivers, there is no solution. Right now, even if you connect via Remote Desktop to Windows, you will find that there is no access to OpenCL.
As soon as the video card manufacturers move the calculation functions to a separate interface independent of the video drivers, there would be some happiness. So far, only Nvidia Tesla is going in that direction.
Add the transfer of raw data to the agent, not as an attached resource, but as an array of data generated in the course of optimisation.
Approx:
void OnTesterInit() { // здесь формируем массив данных (например ArrayPass[]) // и передаем сформированный массив агенту для расчетов return(ArrayPass); }
.
...
Please.
It is the technical details of who, what and how that is of interest.
1. who and how exactly should transfer this data?
2. it is the technical details of who, what and how that are of interest.
1. It should naturally be transmitted by the user, as I suggested above -"Approximately like this:", you know best.
2. Who is who and how, I can't describe )
What are the agents for? - To solve problems.
What tasks do we solve? - I don't know, the main thing is that they solve them.
We need input and output for solving these tasks.
The output is clear, but the input is unclear.
Maybe I missed something? How do I pass the input data (calculated based on previous output data) to the agent?

The point is that we need exactly technically elaborated proposals in at least 2 steps. "Don't know what and how" is not good enough.
How to pass the input data (calculated from previous output data) to the agent
This has already been asked, controlling the progress of optimization would sometimes be very helpful.
But a lot of questions arise on a closer dive (unless the optimization is done on a single local agent).
The point is that we need technically sound proposals in at least two steps. "Don't know what and how" is not good enough.
For our part, we are thinking about independent communication between agents without a terminal. For example, one of the agents could generate the initial data and send it to the others by fordcast.

It's a little bit different. I wanted to control the course of optimisation.
That is, to generate parameter sets as the optimization progresses and send them to the agents for execution.
Naturally, there will be a lot of questions. I'm not ready to answer them.

Not everyone knows that the MetaTrader 5 tester can test not only trading strategies but also solve a whole class of universal problems. For this purpose there is a special mode "Mathematical Calculations", which disables data delivery of the market environment, which greatly saves the amount of transferred data.
Currently we have implemented a number of important functions for the construction of a universal calculation network:
Of course, this is accompanied by: the security of MQL5, its speed, genetic enumerators, etc.
Hence the question - what other features should be included to improve the capabilities of the computational network?
