P
parallel
application
An application that uses a distributed programming model and can run on multiple processors.
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
software
See RGS.
resource
management role
Nodes with this role manage the allocation of resources to user applications.
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
Administration
Switch
A component of the administration network. The top switch in the administration network; it
may be a logical network switch comprised of multiple hardware switches. The Root Console
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
visualization
array
See SVA.
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
controller
The node on which the optional backup slurmctld daemon runs. On SLURM failover, this
node becomes the SLURM master controller.
SLURM master
controller
The node on which the slurmctld daemon runs.
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
