This is highly field-dependent. My old field – solid state physics – did reasonably well on reproducibility, not least because of a bunch of committed open-source folks who had been burnt by exactly this (and by licensing their previous code commercially and getting screwed by their publisher, preventing them from reproducing their own work) working on ABINIT (abinit.org), led by Xavier Gonze. There's a culture around sharing pseudopotentials, too, which is good. SIESTA (icmab.es/siesta) is now open too, I note. That's the team I used to work alongside.
