Research activities in detail
1. Design of computer cluster architecture for HPC, Big data and Data Analytics
The ideal structure of a computing system is related to its specific use and concluding demands and requirements. There are even different even requirements to e.g. computational systems for scientific computation and simulation depending on the communication intensity of the model component. Even more different are the requirements to the processing of large data or even data of Big data category size. Our team is also focussed to the building of such large data analytic tools (Data Analytic) including on-line analytic, which means data analytic in nearly real-time. Examples of such systems are systems of on-line vehicle tracking, e.g. corporate cars, monitoring of their technical state and evaluating of not only of traces and times but also detection of critical places in the infrastructure influencing their reliability.
2. Implementation of parallel algorithms for OpenMP, MPI, CUDA, openACC, Chapel, Spark and Scala environments
It is not possible to process data in an acceptable time and it is not possible to use parallel computer systems, especially clusters, without parallel algorithms implemented in the related programming languages and software environments. The team focuses on to design of simulation, computing and analytic algorithms optimized to parallel HW and SW including advanced algorithms of artificial intelligence, as hierarchic and hybrid evolutionary algorithms.
3. Detection and analysis of object movement in the space and time, temporal data processing, distributed and NoSQL databases
There were developed algorithms for the detection of critical points in the infrastructure for databases containing many millions and billions of records about vehicle movements.
4. Information systems for transport, Data Analytic
Also, there was developed an evolutionary algorithm for train delay distribution function formation from large databases, which is capable to find the analytic description of related distribution functions for given train delay data set.
