onboard	See OA.
administrator
P
parallel	An application that uses a distributed programming model and can run on multiple processors.
application	An HP XC MPI application is a parallel application. That is, all interprocessor communication
	within an HP XC parallel application is performed through calls to the MPI message passing
	library.
PXE	Preboot Execution Environment. A standard client/server interface that enables networked
	computers that are not yet installed with an operating system to be configured and booted
	remotely. PXE booting is configured at the BIOS level.
R
remote graphics	See RGS.
software
resource	Nodes with this role manage the allocation of resources to user applications.
management role
RGS	HP Remote Graphics Software. A utility that enables remote access and sharing of a graphics
	workstation desktop.
role	A set of services that are assigned to a node.
Root	A component of the administration network. The top switch in the administration network; it
Administration	may be a logical network switch comprised of multiple hardware switches. The Root Console
Switch	Switch is connected to the Root Administration Switch.
root node	A node within an HP XC system that is connected directly to the Root Administration Switch.
RPM	Red Hat Package Manager.
	1. A utility that is used for software package management on a Linux operating system, most
	notably to install and remove software packages.
	2. A software package that is capable of being installed or removed with the RPM software
	package management utility.
S
scalable	See SVA.

array
serial application	A command or user program that does not use any distributed shared-memory form of
	parallelism. A serial application is basically a single-processor application that has no
	communication library calls (for example, MPI, PVM, GM, or Portals).
	An example of a serial application is a standard Linux command, such as the ls command.
	Another example of a serial application is a program that has been built on a Linux system that
	is binary compatible with the HP XC environment, but does not contain any of the HP XC
	infrastructure libraries.
server blade	One of the modules of an HP BladeSystem. The server blade is the compute module consisting
	of the CPU, memory, I/O modules and other supporting hardware. Server blades do not contain
	their own physical I/O ports, power supplies, or cooling.
SLURM backup	The node on which the optional backup slurmctld daemon runs. On SLURM failover, this
controller	node becomes the SLURM master controller.
SLURM master	The node on which the slurmctld daemon runs.
controller
SMP	Symmetric multiprocessing. A system with two or more CPUs that share equal (symmetric)
	access to all of the facilities of a computer system, such as the memory and I/O subsystems. In
