SC@FIT - Supercomputing Technologies Research Group
The Supercomputing Technologies group focuses on the architecture and implementation of high performance computing systems, their operation and energy efficiency. The group specialises in the design and development of highly optimised algorithms, communication overhead reduction and scalability. The group's principal application is the k-Wave toolbox for tissue realistic simulation of ultrasound wave propagation.

Current research themes
The research group currently works on the PAMMOTH project on the photoacoustic breast screening. The group is involved in the data collection, on-the fly data quality assessment, and the offline processing on the supercomputer. The image reconstruction is done using our massively parallel implementation of the k-Wave toolbox based on the local decomposition of spectral methods. The full processing automation and monitoring is ensured by the in-house tool k-Dispatch
The group also participates in the project focusing on neurostimulation and neurosurgery. Here, we have been developing the elastic wave simulator accounting for both compression, and shear waves and a novel numeric method for solving problems with jump discontinuities.

The SC@FIT research group offers collaboration in the design and development of applications demanding high compute power, large operational memory and big data. We have deep experience in the R@D of scientific codes for shared memory systems (high-end servers), distributed systems (clusters) and hybrid systems with processors and graphics processing units.
The group also offers the application of the k-Wave toolbox for the nonlinear simulation of ultrasound wave propagation in medical and industrial problems.
