Re^4: Error in calculation on two processors

I do have a permission, because i can work on 1 processor.
cleanipcs was helpful this time.
So file goes, but only on 1 processor instead of 2, as i
write in command line. why?

I attached inp, out, dat, irc files, printcreen of commands
and my printcreen  of my work directory.
