History of Data Centre Development
International audience; Computers are used to solve different problems. For solving these problems computer software and hardware are used, but for operations of those computing facilities a Data Centre is necessary. Therefore, development of the data centre is subordinated to solvable tasks and computing resources. We are studying the history of data centres’ development, taking into consideration an understanding of this. In the beginning of the computer era computers were installed in computing centres, because all computing centres have defined requirements according to whom their operation is intended for. Even though the concept of ‘data centre’ itself has been used since the 1990s, t…
Computing Platform for Virtual Economic Activities Index
The authors enter three economic activity indices, which are calculated from the data in the virtual space on basis of Mobile Operator Call Description Records, Internet Log Files and News Portal audience textual comments and remarks analysis. The article provides the computing facility and the software specification for the Big Data computational platform. Indicates the need to comply this platform with strategy of data privacy requirements solutions and the visualization of results with data geographical mapping.
Unified computing facility design based on open source software
The article describes e-infrastructure development in Latvia and migration to national Cloud as regional partner facility (RPF) in European Union (EU). In Latvia many public and private Computing Clouds is in operation and problem is how to integrate these resources as one RPF and how to design one unified computing facility that is used for many different applications. The authors offer their solution at Cloud software as a Service and Hardware as a Service level which is based on usage of open source packaged bundles.
Milestones of complex computing facility assembling
IMCS UL continues its enduring development of research e-infrastructure, participates in international projects such as GEANT, GN2, GN3, GN3+, GN4, BalticGRID, BG II and EGI-InSPIRE, has involved in CLARIN and ELIXIR ESFRI ERIC activities. Currently IMCS UL maintains Scientific Cloud unified computing facility realized as ½ PTB SAN storage (IBM DS4700 with servers); provides collocation, hosting and virtualization services. As well it operates as a node for online correlation data streaming services from Irbene radio telescope in real time, HPC resources' disposal for computing tasks, usage of Big data extracted from data storage for modeling and also for graphic data processing. In the sam…
ICT History Study as Corporate Philanthropy in Latvia
There are two ICT museums in Latvia: the Riga Technical University Telecommunications Museum and the Computing Museum of the Institute of Mathematics and Computer Science of the University of Latvia. Historical studies can be carried out at museums, institutes and universities, and professional communities. The type of history study funding can also vary. The article describes the possibilities for financing of computer museums. A comparison of museum metrics in the United Kingdom, Germany, the Netherlands and Latvia, Lithuania, and Estonia is subject to discussion. This comparison outlines the possible future museum reforms in the Baltic States. The authors review the public and private fu…
ZERO: An Efficient Ethernet-Over-IP Tunneling Protocol
An Ethernet over IPv4 tunneling protocol is proposed, which categorizes all Ethernet frames to be tunneled into NICE and UGLY frames. The UGLY frames are tunneled by traditional methods, such as UDP or GRE encapsulation, resulting in substantial overhead due to additional headers and fragmentation usually required to transport long Ethernet frames over IP network typically limited to MTU=1,500 bytes. Meanwhile the NICE Ethernet frames are tunneled without any overhead as plain IPv4 packets due to non-traditional reuse of “fragment offset” or “identification” field in the IP header. It is shown that for typical Internet traffic transported over Ethernet, the proposed ZERO tunneling protocol …
Computing and communication convergence reflection to legislation system and higher education programs
Concept of computing and communication convergence has many years of history — as strategic concept it started about 1977 and yet have many definitions. The idea behind convergence concept mostly related to getting closer computing and telecommunication common technologies, services and service provider's business models. In this academic position paper some less significant obstacles of influence-reflection of convergence to legislation system, higher education programs and industry labor market are discussed.
Research Directions Profile in the Computing Museum of the Institute of Mathematics and Computer Science, University of Latvia (IMCS)
The article describes the development of information technology in Latvia, in IMCS, to the middle of the 1990s. The history of IMCS represents the usage of computers in typical computing centers in the former Soviet Union and the transformation from computing center to research institution. It also represents Latvian collaboration with the Nordic countries that provided political, scientific, and technological support. Historical documents, computer parts, and photos are collected in the Computer Museum of IMCS.
