Grid Computing for Electromagnetics

Glossary

A-C

Abstraction
Feature of the object-oriented programming model, according to which entities (objects) having common properties can be grouped.
Abstract device interface (ADI)
Code that must be implemented to specialize MPICH for a specific computing platform.
Arithmetic and logic unit (ALU)
According to the Von Neumann model, the ALU is a component of the CPU and is responsible for executing the instructions.
Application programming interface (API)
APIs facilitate the development of programs using functionalities embedded in software or hardware tools. A tool contains an API when it defines a number of function calls (interfaces) to access its own facilities.
Asymmetric key
A separate but integrated key pair, comprised of one public key and one private key. Each key is one way, meaning that a key used to encrypt information cannot be used to decrypt the same data.
Asynchronous
Asynchronous tasks execute independently of each other, and their timing is not synchronized. For example, when you start up three asynchronous tasks, even when each does about the same amount of work, you can't predict in which order they will finish.
Authentication
Verification of authenticity of communicating parties.
Authorization
The procedure for granting access to resources.
Autonomic computing
Self-managing computing model named after the human body's autonomic nervous system. An autonomic computing system controls the functioning of computer applications and systems without input from the user, in the same way that the nervous system regulates the body system without conscious input from the individual.
