So, the answer to my previous question posed to J. Kerrigan is: protein
/protein distance, hence -d > 0.5*("largest of rvdw or rcoul ").

BTW, why so many people talk about the advantages of using PME, but still
use coulombtype = cuttof?
Time computational cost? Bad scalling in parallel runs?
I assume that rvdw=rcoul=1.4 means that you're doing cutoff for vdw and
