Supercomputers are universal tools for carrying out tasks requiring high-performance computing that could not be handled by traditional computers or server systems. The primary objective is to serve applications requiring extreme amounts of computing, extreme speed, or huge memory capacities.

For comparison, a laptop with a 3-GHz processor is capable of completing 3 billion computations in a second. The performance of the 5 petaflops Komondor is 5 trillion (million times billion) floating- point operations per second.

Supercomputers may help find solutions to global challenges and answers to scientific questions and may help model the weather around the globe, the biosphere, the functioning of living organisms, and the birth of galaxies. In everyday practice, they help with tasks such as weather forecasting, climate research, telecommunications, traffic management, energy production, production optimisation, or customised medicine with the rapid processing of genomic data.

For processing structured or unstructured datasets of extreme size, for various modelling and simulation tasks, and for mechanical, flow, thermodynamic, or electromagnetic calculations. For research, design, production, measurement, testing, and logistics analyses requiring large processing capacities, for the operation of machine learning systems, and for artificial intelligence, Big Data, and IoT applications. Practically, supercomputing can be used in all scientific fields and is also widely used by the industry.

Yes, there is! KIFÜ has been operating a supercomputer infrastructure in Hungary for more than 20 years. Currently, it maintains 6 supercomputers in 4 cities with an aggregated computing capacity of almost 0.5 petaflops. Komondor, which is planned to be available from 2022, will have 10 times this capacity: 5 petaflops.

Although the supercomputer infrastructure is of extremely high performance, it is a limited resource, and therefore requires careful capacity management. Users may include institutions of higher education, research institutions, and their partners, or – when certain conditions are met – innovative market players pursuing research and development activities.

Our supercomputers may be used by those with a valid project number, for the tasks specified in the application for that project number, and within the framework of the quotas assigned. Applications for project number(s) can be submitted after an eduID login at

In Hungary, the use of our supercomputers is free for authorised users.

The reconstruction of the building that will host the latest Hungarian supercomputer, Komondor – which represents a jump in the orders of magnitude – is underway in the Supercomputer Centre of Debrecen. By the fall of 2022, it will be operational and used by both scientists and users from the competitive markets (industrial, commercial, and services sectors).

Komondor will have a performance which is 10 times higher than the total capacity of the existing Hungarian supercomputers; it will reach 5 petaflops, which means 5 billion times a million computations in a second.

Supercomputer performance is expressed in flops. This unit of measure refers to the number of floating point operations (e.g., addition, subtraction, multiplication and division) carried out in a second; FLoating point Operations Per Second, i.e., flops.

Name Value Number of operations per second
kiloflops 103 thousand
megaflops 106 million
gigaflops 109 billion
teraflops 1012 trillion
petaflops 1015 quadrillion (a thousand trillion, i.e., billion times million)
exaflops 1018 quintillion

The future of supercomputers is exascale computation, which refers to computer systems that are capable of carrying out a billion times a billion (one exaflops) high-precision computations per second. Reaching that capacity represents enormous progress – 1000 times higher performance – in comparison with the first petascale computers put into operation in 2008.

The site has been ranking the top 500 non-distributed supercomputer systems with the highest performance in the world since 1993. This list is updated twice a year. In June 2020, the Japanese Fugaku headed the list with a performance of 415 petaflops, which was significantly higher than the 266.7 petaflops performance of the second ranking supercomputer, Summit.

The development of supercomputers is extremely fast; that is why the top 500 list is updated twice a year. Over the past decade, the performance of supercomputers has been increased by orders of magnitude – supercomputers of the petascale category have existed since 2008 – while their scope of application has also been extended.

For two decades now, KIFÜ has been developing a supercomputer infrastructure in Hungary in 4- to 5-year cycles in order to keep up with the world.

It is the abbreviation for Central Processing Unit, which is responsible for the operation of the entire system and for running the programs. One fundamental component of a CPU is the processor core, which executes the specified tasks. As regards structure, a CPU can be a single-core or a multi-core unit.

It is the abbreviation for Graphics Processing Unit, which is responsible for executing graphics operations. GPUs optimised for supercomputers may comprise up to 4 GB of on-board memory, and are capable of maintaining memory bandwidths exceeding 100 GB/s.

Translator programs, libraries, and other development tools of computer programming languages, as well as various software environments required for running parallel applications, HPC tools for Linux-based environments, optimised parallel mathematical libraries, and several licensed and open-source HPC applications are available in supercomputers.

The theoretical maximum of the electric input of the new Hungarian supercomputer, Komondor, is 1.3 MW/hour, but the actual consumption will depend on the final configuration, external temperature, and rate of use.

In Hungary, the average electricity consumption is 2168 kW/year per capita; that is, our latest supercomputer consumes as much as, for example, the town of Jászfényszaru (assuming near-maximal use rate). And all this while it will have a special so-called adiabatic, i.e., direct hot water-based cooling system to reduce the cooling costs.

Consumption is proportional to performance: Tianhe-2 (33.9 petaflops, 3.12 million processors) – a supercomputer located in the supercomputer centre of Guangzhou, China – has an electric input of 17.8 MW/hour, which is equivalent to that of a settlement with 72,000 inhabitants.

Through a high-speed optical network. Komondor will communicate with the outside world at a bandwidth of 100 GB/sec through HBONE+, the backbone network serving academic education, public education, research & development, libraries and public collections, and several other public institutions in Hungary.

HBONE is KIFÜ’s backbone network serving academia, public education, research & development, libraries and public collections, and several other public institutions in Hungary. The dedicated, high-capacity and reliable (telecommunication) network of HBONE provides the basis for the other services.

The new generation HBONE – also referred to as HBONE+ – was completed in late 2010, and represented significant technological progress. This is not an IP network anymore but a so-called hybrid infrastructure, which uses DWDM technology in addition to the IP layer. This provides great flexibility and on-demand scalability.

HPDA, that is, High Performance Data Analytics is enabled by the fact that supercomputers execute operations in a parallel fashion. This allows running high-performance analytics software programs at speeds exceeding the teraflops scale (i.e., one billion floating point operations per second).
