Automatic disk Read/Write when numbers exceed available RAM

[Gaj Satha]

The problem I have is that numbers have become so big that I can’t store them in my RAM. Is there a way I can smartly write portions of my number to the hard disk and load them when needed?

Essentially what I want is that when the RAM is full, just write to the disk and load is automatically without me writing the logic of disk read/write.

No, unfortunately there is no automatic facility to do this other than
the swapping mechanism of your OS.

But in the OP's code!. One can allocate the mpz_t directly into virtual memory using your os'es facilities (VirtualAlloc/mmap) or use Boost.Interprocess to achieve the same in a cross-platform way. Wrapping an mpz_t (putting it in vm) is the way I think).
