How to implement parallel computing?

Question

Game development

Advise what to read and what platform to use (I was thinking about node.js) to solve the following problem:
for a group of objects (say up to 10000), some calculations must be performed in the background, and for each object there should be 1 second between a pair of calculations.
If you perform calculations by enumeration, then with the growth of the number of objects, the time between calculations of each object increases.

Answer 1

The node, though fast, is single-threaded. better take erlang or go.

Answer 2

Go is very well suited for such a task - you can start and calculate a separate goroutine for each of the objects

Answer 3

Depends on the type of calculation...
If you have a map and a lot of objects - you can use the overlay of the previous iteration to determine the shifted / changed objects (others - immediately exclude).
In difficult situations, a tree is created. As a result, you count only changed / moved objects, and not everything in a row.
You can also use the base for intermediate calculations:
SELECT (17 + 23) / SQRT(64);

Answer 4

In general, there are many options for how this can be done. You can also tie CUDA / OpenCL.
