Filtering out N/A did not work

[fgeorgatos]

nor did, filtering in node (under SGE)

[sfranky]

The empty cores are added in only after the filtering has taken place. If you do not need the empty N/A machines, then apply blind remapping ("-a") and force names ("-F") so that nodes don't get renamed to consecutive numbers.

@fgeorgatos Filtering indeed does not work in non-remapped mode, as filtering itself is some sort of remapping.. Will have to look into that deeper, if you find it useful (but do you?)
