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.

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.

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
