The report for 1990
In 1990, the collective efforts of the Laboratory were aimed at improving the quality parameters of the central computer system of the Institute, local area networks and
terminals. The works on the development and effective use of personal computers and image processing chamber systems. Abstract methods and set up a program for solving nonlinear problems of mathematical physics in connection with the developments at JINR. Developed and implemented software systems for the analysis of experimental data.
Development and efficient use computing center, local networks and personal computers
As part of the JINR put into operation two EU-1066 computer and the second EU-1037 computer. Created multiple computer complex UCS based on the total disk space. EU-1037 computers connected to the network JINET (Joint Institute NETwork) through the EU-8371 teleprotsessor, and they serve as a computer terminal. Only interactively can operate with more than 100 users simultaneously complex. Total UCS capacity is 16 million. Operations per second (MIPS) at a basic computer and an additional 24 million. Operations per second (MFLOPS) on specialized array processor. All complex computer running virtual machine operating system (SVM). To move to the SVM and combining UCS developed new and improved existing programs and data teleprocessing inter-machine communication, batch processing monitor, software matrix processor, graphics system, adapted DUBNA general purpose library.

Laboratory of Computer Science and Automation – JINR – Dubna
The report for 1989.
In 1989 he commissioned a new basic EU-1037(IZOT-1014E) computer, the processor of teleprocessing of the EU-8371 Data (PDD) and the disk subsystem for the EU series computer with total capacity of 15.2 GB. With the help of the EU-1037 is included in the PDD JINET (Joint Institute NETwork) network.
Inserted software option for JINET network users with the EU-1037 computer (IZOT-1014E). It created the first stage of complex software EU-1037 computer (IZOT-1014E) and the EU-1061 for operation on the total disk space.
In UCS the transition to work under the control of the operating system virtual machines (SVM). This system provides advanced tools to work in an interactive mode allows you to use more resources to carry out system operation and testing peripherals without impacting users.
A similar system is in operation on the IBM computers at CERN, so provides compatibility of software between the JINR and CERN. Have developed a system-wide software base computer. new translator from the language “C”, the new version of the software packages were commissioned, developed at CERN: GENLIB, PACKLIB, ZEBRA, PATCHY, KERLIB, GEANT, and others.
For CBM system performed adaptation of the software matrix processor ES-2706, graphic packages, and the first version of a general-purpose programming library “Dubna”
Report for 1987
Development and effective use of information center of JINR (Joint Institute for Nuclear Research)
It was connected to the EU-1061 and handed over for operation Matrix processor EU-2706. Made the first attempt to use the processor in solving problems of numerical experiments in SU (2) -calibration field theory. It studied are temperature-phase transition “konfaynment – dekonfaynment” during which the matrix processor working at a speed of 16 mln. Operations per second.
Software products is absorbed mathematical matrix processor: driver service interaction between the EU-2706 and EU-1061 library programs for elementary operations and applications, translators language FORTRAN, APAL and others.

The largest central management of the North County
High performance complex on the basis of EU-1037 and matrix processor EУ-2706. One of the most perspective directions in the creation of computational systems are multiprocessor complexes, which solve problems with large volumes of data using methods for parallel computation.
Array processors (MP) ES2706 provide users Mainframe Computer midrange performance level corresponding to super computers at significantly lower prices. MP are used in areas such as exploration and exploitation of natural resources on land and in the ocean management processes and equipment in space, air, sea and factory design of bridges, buildings, aircraft engines, automobiles, integrated circuits others.
The matrix processor ES2706 is independent. It joins EU with the help of a standard interface for input-output. Productivity MP ES2706 12 million. Arrhythmia. op. / s, or 30 million. equivalent EU op. / s. In MP has its own memory for programs, which can be uploaded throughout the custom processing algorithm and data memory of up to 4 Mbps. The programming is done on mikro-asembler ARA or high-level language FORTRAN AP-77.
At the end of 1988 was in service IZOT-1014E, which consisted of powerful mini-EIM to open micro program level and four EU matrix processor 2706, may consider parallel. At the end of the 1980s UNVK became the most powerful center in the University of total volume of disk memory and fast computing resources.
No less important was the fact that in creating its own computing base, realize certain concept, which involves the development of terminal network of classrooms, departments and laboratories. The supply of faculty with the most modern equipment was for use not only for scientific purposes, but also for the training of students.

Computing Machinery Works – SOFIA
Brief history of the period 1968-1977 year.
Computing Machinery Works was established by the 12th decree of the Council of Ministers of 17.11.1967, with the purpose to produce digital electronic computing, electronic calculators and other computing resources.
Due to lack of its own production facility, the plant is housed temporarily in the building of the Research Institute for Automation -Str. “Jordan Visegradski” 46 – Sofia, District People’s Council – Kirkov.
On the grounds of Paragraph 2 Item 6 of the decision of Council of Ministers 358 of 6.09.1968 g Executive Committee of the Gallery shall issue a decision by a report on 9/15/1968 emphasis on a plot of 200 acres north of the road Sofia-Plovdiv at the seventh kilometer, just against physical Bulgarian Academy of Sciences and in 1968 began construction of its own building the plant, which ended the 1972-73 year.
By letter 5235 of 08.01.1971 of the Committee for science, technical progress and higher education on the basis Decree 24 of 1971 form to plant electronic data center.
From September 1972 to factory creates industrial-training center.
The plant is managed by a director, deputy directors, there are directional and business advice. In the administration are separate production, technical, economic and commercial department.

The series of machines was manufactured between 1967 and 1971. They were integrated in the Regional Computing Centers in Bulgaria. The project was under the direct guidance of Ivan Marangozov.
ZIT 151 has capabilities equivalent or better than Facom 230-30. It uses some improvements from Facom 231 increasing the capabilities of the initial machine. The following execution speed was achieved for 10-bit integer arithmetic operations:
addition – 58.3 μs
subtraction – 82.5 μs
multiplication – 850 μs
While the following processing speed was achieved for floating-point instructions:
addition – 150 μs
subtraction – 200 μs
multiplication – 1400 μs
The magnetic-core memory had 2.2 μs access cycle. The memory capacity was increased compared to Facom 231 two times to the maximum 64KChar [2], where har(hartley) is a unit of information equal to log210 = 3,323 bit.
production cooperation
Acquisition of EIM than the original parts supply lease was produced by ZIT made in metal structures of cabinets. In the factory we have developed tools for the production of printed circuit boards, connectors, connecting cables and machining. Chemical processing, drilling and installation of the boards is done in ZIT. PCB soldering is performed on specialized machine purchased “tin wave”. The cabinet OU (operational storage) and the PM (permanent memory) is made based on ferrite cores in ZZU (Plant memory devices) – Veliko Tarnovo. The production of memory devices on magnetic tape (ZUML) are incorporated under license in the eponymous factory in Plovdiv.. Electric typewriter for input and output of EIM is produced in the factory typewriters – Plovdiv. Japanese card reader and reader tape were replaced with such devices chess company “Arrhythmia”. Wide printing is imported from the US production company “Hewlett Packard” (5 pieces) and Polish production TURBOSNACK • fastest wide print DW 21 produced an English license.
