How to expand the amount of RAM on a computer up to 10 Terabytes (speed is not important)?

Question

Computers

I need 5-10 terabytes of memory on my computer (speed is not critical).
There is software that loads trees into memory for calculation and it is tied to the amount of RAM, but it's expensive for me to buy such a volume.
Question: Is it possible to connect a regular hard drive so that the computer sees it as RAM?
Maybe there are other ways?
Just don't suggest optimization. The software is not mine, so I can’t do anything with it at the moment.

Answer 1

And how did this software even work somewhere????
Do you use software from the nuclear research center in Zurich?
It is unlikely that you will succeed, since you are close to the limit (since you did not specify the OS, I will assume that this is defaultOS):

If you still want to try, then the page file on the SSD is a typical and common method for solving such problems in the forehead.
It will be used automatically. That is, nothing depends on your software.
But in general, applications that really need such amounts of RAM are developed in a special way and run not on all OS distributions, but only on certain ones.

Answer 2

Try to force a 5-10TB swap file

Answer 3

Ram 1-2Tb - put really. Expensive, but real (upd: in the comments they indicated that it’s not so expensive in the cloud)
Then you can use pci ports
There are solutions for ssd + ram in pci with good speed and sizes of
1-2Tb software optimization for existing platforms for spreading tasks across a cluster of cheap PCs with 128GB of RAM on board

Answer 4

Obviously swap to use, in Windows the swap file

Answer 5

well, just download a 10tb swap file
