What are Processor Sets?
HP-UX Processor Sets offer a flexible mechanism for managing system processor
resources among multiple workloads, users, and departments within an enterprise.
A processor set represents a set of processors grouped together for exclusive access to
applications assigned to that processor set. Each application is assigned to a processor
set and will run only on processors in the assigned processor set.
Processor sets allow partitioning of the system into multiple Scheduling Allocation
Domains, such that workloads running in different processor sets do not contend with
one another for system processor resources. This capability makes server consolidation
on large systems more efficient.
Resource management based on processor sets is completely hardware platform
independent and can be used on any HP-UX 11i multiprocessor system.
Processor sets are integrated with HP-UX Process Resource Manager. A PRM group can
now be mapped to a processor set for processor resources rather than processor shares.
NOTE Any application that programatically uses the processor sets system call interfaces must
be compiled with the header files installed with the Processor Sets product.
