COMSCI 2101 - PROCESSOR MANAGEMENT (CHAP 4)

LOOSELY COUPLED CONFIGURATION

Utilizes a network of independent nodes working together without a central control point.

PARALLEL PROCESSING

for better speed, ____________ involves execution of tasks over several processors or CPU cores. It is frequently employed for computationally heavy/intensive tasks.

CONCURRENT PROCESSING

The ability of a system to manage several tasks or processes simultaneously.

CONCURRENT PROCESSING

These tasks can be carried out in an interleaved manner, giving the impression that the system is working on multiple tasks at once.

CONCURRENT PROCESSING

This processing is often used to improve the responsiveness of a system and to efficiently utilize resources.

CONCURRENT PROGRAMMING

In programming term, ________ is a technique in which two or more processes/task start and run in an interleaved manner through context switching and complete in an overlapping time period by managing access to shared resources.

CONTEXT SWITCHING

Concurrent Programming is a technique in which two or more processes/task start and run in an interleaved manner through ____________ and complete in an overlapping time period by managing access to shared resources. For example, a single core of CPU.

PARALLEL PROCESSING

It is a situation in which two or more processors operate in unison.

PARALLEL PROCESSING

That means two or more CPUs are executing instructions simultaneously.

PARALLEL PROCESSING

This is done to increase computing performance and speed generally.

PARALLEL PROCESSING

Increased flexibility brings increased complexity, however, two major challenges remain:
- how to connect the processors into configurations, and
- how to orchestrate their interaction, which applies to multiple interacting processes as well.

- MASTER/SLAVE CONFIGURATION
- LOOSELY COUPLED CONFIGURATION
- SYMMETRIC CONFIGURATION

3 TYPES OF MULTIPROCESSING CONFIGURATIONS

MASTER/SLAVE CONFIGURATION

There is a clear distinction between a MASTER PROCESSES and one or more SLAVE PROCESSORS.

• The MASTER controls the overall operation of the system.

• The SLAVE execute specific tasks or workloads assigned to then by the master.

SYMMETRIC CONFIGURATION

• All processors or CPU cores are considered equal, and they have equal access to the system's memory and resources.

• There is no master/slave processors; they all contribute to the processing tasks.

MASTER/SLAVE CONFIGURATION

Involves a clear hierarchy with a master controlling one or more slaves.

CONCURRENT AND PARALLEL PROCESSING

Both processing are crucial ideas in modern computing, and both
can be used to enhance system responsiveness and performance.

TIGHTLY COUPLED CONFIGURATION

symmetric configuration is also called ______

CONCURRENT PROCESSING

Different tasks are executed one after another.

PARALLEL PROCESSING

Involves simultaneous execution of multiple tasks using multiple processors or CPU cores.

PARALLEL PROCESSING

Each processor is executing a separate task at the same time.

PARALLEL PROGRAMMING

In programming terms, __________ is achieved through hardware parallelism. For example, executing processes on three separate CPU cores simultaneously.

LOOSELY COUPLED CONFIGURATION

• Each processor has its own dedicated resources.

• When a job arrives for the first time, it is assigned to one processor.

• Once allocated, the job remains with the same processor until it's finished.

SYMMETRIC CONFIGURATION

All processors or cores are equal and work together in a balanced manner.

CONCURRENT PROCESSING

________ is the management of several tasks or processes in a way that it appears as they are running simultaneously, frequently to increase system responsiveness.
