And imagine 9 more zeros with 64bit compiler? LOL Does Intel use stack by the way?
There are types of problems which look crippled in 32bit and ones which are not even possible with 32bits as they need minimum 16GB like some our 3D PIC plasma simulations. If you use less than that the numerical fluctuations are so large that they create fake physics reality. Intel's Knight Landing processor with 72 64bit cores combined with the future Silverfrost 64bit FTNXX supporting OpenMP would be great home supercomputer i think
