Operational Analysis of Processor Speed Scaling

HPL-2009-9 Operational Analysis of Processor Speed Scaling - Shen, Kai; Zhang, Alex; Kelly, Terence; Stewart, Christopher
Keyword(s): performance modeling, performance prediction, capacity planning, system management, operational analysis, multicore processors, processor speed scaling ACPI P-states, parallel computing, occupancy curve
Abstract: This brief announcement presents a pair of performance laws that bound the change in aggregate job queueing time that results when the processor speed changes in a parallel computing system. Our laws require only lightweight passive external observations of a black-box system and they apply to many ...

pset_assign_cpu

pset_assign_cpu(1)					      General Commands Manual						pset_assign_cpu(1)

NAME

       pset_assign_cpu - Assigns a processor to a processor set

SYNOPSIS

       /usr/sbin/pset_assign_cpu pset_id processor [processor...]

       /usr/sbin/pset_assign_cpu -a  pset_id number

OPTIONS

       Adds the specified number of processors (number) to the specified processor set (pset_id) from the default processor set.

DESCRIPTION

       The  pset_assign_cpu  command  assigns  one or more processors to an existing processor set.  The pset_id variable is a unique integer that
       identifies the processor set and is returned by the pset_create command.  The processor variable is a unique integer  that  identifies  the
       processor.   Each  processor  that  is assigned to an existing processor set is removed from its current processor set.	The boot processor
       cannot be assigned.

       Processor assignments are logged in the /var/adm/wtmp file.
