This depends on how much memory is available to you. The file formats have an
upper limit of a million atoms, but you may run out of memory before that.
Further, since large systems take a long time to equilibrate, and are slow to
run, the practical limit may also be determined by how much computer time you
have available.

No. Memory is allocated dynamically, with no fixed upper limit.
