Short answer: no.  You mean the app uses e.g. max 50% and if nothing
else is running the CPU is then 50% idle?  There was a long thread on
OpenBSD (where people discuss kernel internals) that concluded that UNIX
has never had a scheduler that could do this. 

What problem are you trying to solve where you think that this is the
answer?
