Standard terminology in CS is more or less the reverse.  "Concurrent"  
means apparently happening at the same time, "parallel" means executing on
more than one CPU.  Multi-threaded programs are concurrent, but they're
only parallel if they're running on more than one core.

Of course, these things can change.  "Core" used to mean RAM.  Now it
means CPU.

Tom Duff.  PLEASE GO ON.
