Depends on the operating system. There is no standard API for doing this.
I suggest that you consult the documentation for your operating
system, and find out if there is a way to bind a process (with all
its child processes) to a specific CPU.
I don't know why you would want to keep 7 CPUs idle while only one
is doing work. It is not like this would give you isolation of
performance. The different CPUs are still competing with each other
for access to memory, disk and network.
Perhaps you need something like Solaris zones (containers) that
support some form of QOS guarantees.
