We recently have been looking at the wording in our tutorials too and I 
think it might be confusing to use terms like 'uni-processor' or 
'multi-processor'. The main reason is that MPI and multi-threading is 
about processes, not processors. On what processor these processes will 
be scheduled is up to the OS (generally). My experience is that the 
scheduling of processes on processors is something very confusing for 
users and using these terms might add to that confusion. And indeed, 
once users are dealing with multi-core processors, this will be even 
more confusing.
