A parallel processing laboratory is established with the aim of leveraging advanced computing systems to improve processing speed. Since almost all modern architectures are based on parallel systems, the focus in this laboratory is on designing and implementing parallel algorithms to achieve optimal compatibility with these architectures.
Given the high cost and complexity of this equipment, it is recommended to consult Simulators in AmirKabir University for renting such laboratories.
What is parallel processing?
Parallel processing is a method of computation where two or more processors (CPUs) handle separate parts of a task simultaneously. Dividing a task into different parts and distributing them across multiple processors helps reduce the execution time of programs. Any system with more than one CPU can perform parallel processing, as can multicore processors found in modern computers.
Multicore processors are IC chips containing two or more processors, allowing for more efficient operation, reduced power consumption, and effective multitasking. These setups are similar to installing multiple separate processors in a single computer.
In a parallel processing lab, most computers may have two to four cores and even exceed 12 cores. Parallel processing is commonly used for complex tasks and calculations. Data scientists often utilize parallel processing for heavy computational workloads.

How does parallel processing work?
Typically, a computer expert uses software tools to break down a complex task into smaller components, assigning each to a separate processor. Each processor solves its assigned part, and the software combines the data again to produce the final solution or complete the task.
In a parallel processing lab, each processor extracts data from the computer’s memory and performs operations in parallel. Processors also rely on software to communicate and synchronize changes in data values. Assuming all processors stay synchronized, the software aggregates the results at the end. Even computers without multiple processors can perform parallel processing when networked to form a cluster.
In a parallel processing lab, different types of parallel processing exist. Two of the most common are SIMD and MIMD.
Another less common type is MISD (Multiple Instruction, Single Data), where each processor uses a different algorithm on the same input data.
While parallel processing utilizes multiple processors to execute multiple tasks simultaneously, serial (sequential) processing uses only one processor to perform one task at a time. If a computer with serial processing needs to perform multiple tasks, it completes them one at a time. Similarly, solving a complex task using serial processing takes longer than using parallel processing.
Parallel processing is a computational method that divides a complex task into separate components executed simultaneously on multiple processors, reducing processing time. Scientists typically use parallel processing tools to assign tasks to different processors and aggregate the results post-computation. This process can be performed via a network of computers or on a single computer with multiple processors.
Parallel processing and parallel computing often occur simultaneously, making the terms interchangeable. However, parallel processing focuses on the number of cores and processors running in parallel, while parallel computing relates to how software behaves to optimize these conditions.
A parallel processing lab enables simultaneous data processing, achieving faster execution times. The primary goal of parallel processing is to enhance the computer’s processing capacity and throughput—the amount of work completed within a specific timeframe.
Despite its benefits, setting up a parallel processing lab is neither simple nor cheap. Many companies opt to rent these facilities instead of purchasing and setting them up. In this regard, Simulators AmirKabir Company is a reputable provider offering rental services for these laboratories.
What is the goal of parallel processing?
The goal of parallel processing is to reduce program execution time by dividing tasks among multiple processors working simultaneously.
What is an example of parallel processing?
Parallel processing resembles the brain’s ability to perform multiple tasks simultaneously. For instance, when a person sees an object, they don’t just see one aspect but process several features together to identify the object as a whole.
What are the techniques of parallel processing?
Parallel programming involves multiple active processes solving a specific problem simultaneously. A given task is divided into several subtasks using a technique, with each subtask processed by a different CPU.
