Pemrograman Paralel Pertemuan 1 - Pengenalan Pemrosesan Paralel

Summary

In this first session of the Parallel Programming practical course, the instructor introduces the concept of parallel processing, explaining that it allows instructions or operations to be executed simultaneously, either on single or multiple processors. The session covers the basic architecture of parallel systems, highlighting the relationship between the system and processes in an operating system. The instructor then walks through practical coding examples, explaining different components such as variables, functions, and loops, and shows how to use libraries for parallel programming. The session concludes with a reminder about adjusting parameters and a thank you note.

Q & A

What is the main focus of this first session in the parallel programming practical?

The main focus of this session is to introduce parallel processing in programming, explaining the concept and providing an overview of the course material.

What is parallel programming?

Parallel programming is a technique in computer programming that allows instructions or operations to be executed simultaneously, either in a single processor or across multiple processors in a multiprocessor architecture.

What is the definition of parallelism in this context?

Parallelism is defined as the ability to execute independent instruction flows that can be run by an operating system simultaneously.

How does the parallel processing architecture relate to system operations?

The parallel processing architecture involves the interaction between processors and the system, where multiple processes can be executed at the same time. This relationship is also explained in the operating systems course.

What is the role of the Vitrek Negeri X in the practical?

Vitrek Negeri X is a tool used in the practical, which provides access to certain functionalities such as 'Fitri add-ons' and 'chord.hey Secret Peter', among others, available through the website module.

What is the significance of the variable 'faith = 4' in the script?

'faith = 4' defines a global variable with the value 4, which plays a role in the execution of parallel operations within the script.

What does the 'pointer elevation' parameter refer to?

The 'pointer elevation' parameter refers to an argument passed into a function, and its value is used within a procedure to modify or retrieve data, such as the word 'Helloween' in this case.

What is the purpose of the 'Fitrep' function in this context?

The 'Fitrep' function is used in the script to correct or modify data passed through the procedures, serving as a mechanism to ensure correct execution of parallel operations.

What does the loop in the script accomplish?

The loop in the script runs from 0 to a specified limit, processing data for parallel operations and ensuring that the system continues to function as expected by updating necessary variables or running required procedures.

How does the 'join' function work in the script?

The 'join' function is used to combine threads or processes after they have been executed, ensuring that they synchronize and complete their tasks correctly before continuing further operations.
