Can I solve problem with 1,000,000 variables

I wanna solve a problem with 1,000,000 variables.

but, it is in ‘out of memory’ trouble.
when I reduced the size, it was solved.

so, I wonder that solver can’t solve such a big size problem in general or not.

Maybe you just do not have enough RAM in your computer.

Btw the RAM required is dependent on the structure in the problem e.g. sparsity and number of constraints.

There was a typo. not 100,000, 1,000,000 variables. I edited
and installed RAM is 512GB.

Knowing the number of variables and amount of RAM is not enough information to answer your question.

What about providing log output.
