runon(1) General Commands Manual runon(1) NAME
runon - Runs a command on a specific CPU or processor set SYNOPSIS
runon cpu_num command [argument...] runon -p [-x] pset_id command [argument...] runon -r rad_id command [argument...] DESCRIPTION
The runon utility runs the specified command (command) on the specified CPU (cpu_num), Processor Set (pset) or Resource Affinity Domain (RAD). The argument variable specifies any options or arguments for the specified command. All the threads created by the command inherit the CPU binding to the specified CPU (cpu_num), including threads created as the result of a fork. If the -p option is used, the specified command is bound to a processor set rather than to a specific processor. Because a processor set can contain more than one processor, the -p option is useful for multi-threaded applications. In addition, you can use the -x option to specify exclusive access to a processor set. OPTIONS
Binds to a processor set instead of a processor. You must specify the processor set identification number (pset_id), which is a unique integer that identifies the processor set and is returned by the pset_create command. You can specify the -x option with the -p option. Invokes Resource Affinity Domain (RAD) binding, which binds the command to a RAD identifier (rad_id) instead of an individual processor or pset. The RAD structure holds data associated with a NUMA building block. In this release, and for the purpose of using the runon command, a RAD is analogous to a hardware Quad Building Block or QBB. The hardware QBB identifier also identifies the RAD. However, in future releases a RAD will be defined as a related set of memory, pro- cessors, and I/O that might not map to a discrete QBB. Specifies exclusive use of a processor set. Use the -x option only with the -p option. SEE ALSO
