Information System and System Programming

The aim of this course is to understand the concept of system calls, which are an API for the operating system, and to acquire the technical skills to use them effectively.
In order to learn the technology for constructing advanced systems, it is necessary to understand the programming that abstracts the CPU and memory of the operating system, such as files, multitasking, signals, and multithreading, which are basic software technologies. In this class, based on this understanding, we will work on implementing techniques to evaluate performance and improve it. In addition, we will develop socket programming to realise virtual networks and multitasking servers that integrate these. Through this practical training, we will aim to gain a deeper understanding of software development that achieves high-performance servers, cloud computing and middleware, by understanding how to efficiently use computer resources, such as advanced sharing of memory and CPU.

This course is a practical course in which you will learn the impact of descriptions on performance by programming using libraries and system calls, which are APIs that call the functions of the operating system (hereafter abbreviated as OS), which is the lowest layer of software, and the basic principles that support advanced and complex systems.
Those advanced and complex IT systems that support today’s information technology are supported by advanced computer systems. Computer systems are not only made up of multiple CPUs, but also various accelerators, and are becoming more advanced and complex in the form of parallel and distributed systems. The software infrastructure that supports these computer systems includes communication middleware and operating systems.
The lectures include practical exercises, and cover topics such as files that handle variable-length data, multitasking, signals, and multithreading development, as well as network socket programming that applies these techniques, and the development of multitasking servers as an integrated technology. Through these practical exercises, etc., you will understand software development that achieves advanced sharing of memory and CPUs, high-performance servers, cloud systems, etc. You will learn about the efficient use of computer resources and reliability.
