About us

Laboratory of Advanced Network Technologies was established in 2002 by the Faculty of Informatics, Masaryk Univesity, Institute of Computer Science, Masaryk University and the CESNET association as a joint workplace for research and development of advanced network technologies and applications. The research laboratory is now specialising in

  • high performance computing,
  • interdisciplinary research in chemistry and biology,
  • multimedia and networking,
  • planning and scheduling.

Research Focus

In the area of high performance computing, we mainly focus on automatic code optimization methods (application-parameters autotuning, kernel fusion) and development of highly-optimized parallel programs for conventional CPUs and accelerators. The research is done in close collaboration with CERIT-SC Centre and its research programme.

Our group collaborates on many interdisciplinary projects, mainly in area of computational chemistry and biology. We are responsible for development of novel methods (transport processes in proteins analysis with CaverDock), or parallelization and optimization of existing ones (cryo-EM reconstruction with Xmipp, digital metadynamics in Plumed).

Complex networks are a rich formalism combining graph theory, statistics and complex system modeling. We focus on applications in neuroscience such as changes in whole-brain connectivity in health and disease, and on modeling of dynamical processes on networks, e.g. in historical context.

Very-high quality and low-latency, multi-point audiovisual transmissions bind together research and development in both multimedia technologies and high-speed networks. We participate on the development of the UltraGrid software for low latency and high-quality video network transmissions focusing especially on telemedicine or applications in arts.

Planning and scheduling are research areas with a wide range of applications. Our focus is related to scheduling problems in traffic control, job scheduling and data transfer planning in distributed computing environments or educational timetabling.

More information concerning past and current research topics can be found in the Research section.

Laboratory Equipment

Researchers in our laboratory have access to a unique set of equipment — from high-end commercial systems (e.g., stereo projection in HD resolution or a wide range of videoconferencing apparatuses) to systems of our own construction, part of which has been developed in a cooperation with our foreign partners and commercial companies (e.g., optic multicast switch or a display wall with the 8K resolution (scalable up to 16K).

Laboratory network connection consists of

  • an internal 16x 10Gb/s networking,
  • direct access to the CESNET2 backbone (currently 3x 10Gb/s),
  • access to dedicated DWDM channels for particular application,
  • access to experimental networks such as CzechLight, GLIF or other academic networks included in the GEANT2 project.


The laboratory collaborates with a wide range of foreign and local sites.

In past, we also cooperated with

Beside already mentioned departments at the university, we also cooperate with the Laboratory of formal methods, logic and algorithms (Formela) with joint projects on formal specification and verification of protocols.

We also have continuous cooperation with commercial partners

Teaching activities

The laboratory is a natural educational workplace at Masaryk university, where all under-gradute, graduate and doctoral students can participate on the ongoing research as well as work on their theses. A specialized seminar takes place in the laboratory each semester. Besides, a number of senior laboratory members held courses at Faculty of Informatics, MU including networking classes or the courses focused on parallel programming.

Other Activities

Our laboratory has created and operates a unique system for recording and processing lectures or other events, which is deployed to support life broadcasting and archiving of lectures at MU. This system utilizes our research results for effective processing of multimedia data on computer clusters. Laboratory staff also coordinates (as a part of our connection to ICS MU) the deployment of audiovisual, videoconferencing and other ICE systems through the whole MU, especially in the university campus, which is currently in construction.
