Correct. This is because you are using the "c" notation, which means
"cpu". You must have lambooted with "cpu=2" (or more) in your boot schema
file. If you use the "n" notation (meaning "node"), it'll launch one per
node.
See the mpirun(1) and bhost(5) man pages, as well as the LAM 7.0.x User's
Guide for more details about "c" and "C" vs. "n" and "N".
