Biography of Lebedev Sergey Alekseevich

Lebedev and the development of domestic computer technology S. Lebedev made a fundamental contribution to the formation and development of computational sciences in the former USSR. He developed the main principles of construction and the structure of universal electronic digital computers, organized the work of collectives of developers of high -performance computers, the industrial production of these computers and their implementation, and training.

Lebedev is called the "father of computer technology" in the USSR. His name and significance of his scientific, organizational, pedagogical and social activity are comparable with the names and significance of the activities of academicians I. Kurchatov, C. Korolev, M. Keldysh in the field of atomic energy and the development of space space. The successes in these most important areas of scientific and technological progress are directly related to the use of high-performance computing machines and systems developed under the leadership of S.

Future activities of S. Lebedev in the field of the theory and practice of the design of digital computers, his outstanding works in the field of electrical engineering primarily, the creation of the "artificial stability" of electrical systems and the corresponding automatic regulators and in the field of the creation and use of the creation and use of the creation and use of the creation and use of the use and use Means of analog computer equipment for automating the calculations of the operating modes of electrical networks.

For the years, Lebedev headed the Institute of Exact Mechanics and Computing Technology ITM and Tue of the USSR Academy of Sciences in Moscow, in which he created an active team and a scientific school for the development of the fastest -acting machines requiring a solution to new difficult problems.

Lebedev believed that such developments are the main driving force in the development of computer technology. Earlier, when Creating S. Lebedev in Kyiv, the MAMSM small electronic counting machine, they checked on it the fundamental principles for building computers and specific technical solutions, accumulated experience in setting up and operating computers, programming algorithms of the most important computational tasks.

The first computers, developed under the leadership of S., the possibilities provided by the composition of the BESM-1 operations, primarily operations on the numbers “with a floating-comb” with a large range of numbers and high accuracy of calculations, made it possible to solve large scientific and production tasks. Lebedev proposed many solutions to parallelize the data processing process, the use of new elements and technologies, the modularity of the construction of computing systems, the implementation of which led to a significant increase in computers.

Thus, under the leadership of S. Lebedev, a computer with a performance of 20 thousand. The development of the scientific school S. Lebedev was significantly facilitated by his timely publications and performances at scientific conferences. In the first half of the x years, S. Lebedev organizes work on the creation of specialized high -speed computers focused on work in real -time systems.

In these machines, the entry of information into the machine directly from the communication lines was implemented. The outstanding achievement of S. The high manufacturing of the machine was determined by the use of high -frequency semiconductor elements and its new developed structure. Without exaggeration, we can say that many new principles underlying the BESM-6 serial machine have anticipated what is now considered mandatory for modern computing systems.

Lebedev well understood the need for the joint work of engineers and mathematicians - programmers when creating computing systems. The great capabilities of the machine were an incentive for creating developed mathematical support for it, which allows you to use it effectively. Lebedeva created and used developed methods for designing and descriptions of computers, including imitation mathematical modeling of the operation of devices that contributed to the choice of optimal structural solutions, the use of algebro-logical expressions, which ensured the visibility and ease of understanding of the schemes.

The ideas of the creation of multiprocessor and multi -mass computing complexes of various organizations expressed by S. Lebedev were implemented in the future by the teams of developers ITM and Tue. For many years, these complexes have been successfully used and are used to carry out the most important work, including in space management centers. In the human sense, its main features that note all those in contact with him were justice, trust, exactingness, kindness and a complete lack of a sense of superiority in relation to others.
