Well, that's why it is a "deprecated" option! :-) Looks like the command line parser then gets confused by the error in your option - if you look more closely at the error, you'll see that it picked up the "2" as the name of your executable. This is because "pernode" doesn't take an argument - it is shorthand for "npernode 1". You probably meant to use the "npernode" option, which would have worked.
