Conference Paper
High Performance Computing (HPC) is an interdisciplinary field of study, which requires learning a number of topics, including not only parallel programming, but also numerical methods and domain science. Stand-alone parallel computing courses are insufficient for thorough HPC education. We present an interdisciplinary track of coherent courses dev...
Chapter
We describe an approach to teaching Machine Learning and High-Performance Computing classes for Master students at Ural Federal University. In addition to the theoretical classes, the students participate in the projects in collaboration with the partner companies and research laboratories of the university and institutes of the Russian Academy of...
Conference Paper
Software systems have established themselves as the heart of business and everyday living, and as the pillar of the emerging global digital economy. This puts pressure on educational institutions to train people for the continuously evolving software industry, which puts additional demand for new PhDs and educators. While large universities and res...

Spiral waves in the heart underlie dangerous cardiac arrhythmias such as fibrillation. Low-voltage defibrillation and cardioversion are modern methods to treat such pathologies. This type of electrotherapy is based on the phenomenon of superseding spiral waves by a high-frequency source of excitation. In this paper, we numerically simulated the sup...

In the heart, scroll waves are three-dimensional self-sustaining spiral waves of electrical excitation. They arise only in pathology and underlie dangerous arrhythmias. Computer simulation of human cardiac arrhythmias is time-consuming and requires parallel computing. In addition, heart simulation is a complicated multilevel task (cell, tissue, org...
Conference Paper
In this paper we present an approach to the parallel simulation of the heart electrical activity using the finite element method with the help of the FEniCS automated scientific computing framework. FEniCS allows scientific software development using the near-mathematical notation and provides automatic parallelization on MPI clusters. We implement...

This study demonstrates a software system for simulating the electrical and mechanical activity of the heart left ventricle (LV). The distinguishing feature of the system is the use of the heart anatomy model, which is based on an analytic description of the ventricular shape and fibre orientation. Another important system feature is that the simul...
Conference Paper
Full-text available
Modern image collections cannot be processed efficiently on one computer due to large collection sizes and high computational costs of modern image processing algorithms. Hence, image processing often requires distributed computing. However, distributed computing is a complicated subject that demands deep technical knowledge and often cannot be use...
Conference Paper
Full-text available
We present the LeVen computational system for simulation of the electro-mechanical function of the left ventricle (LV) of mammalian heart on parallel computers. A macroscopic LV model incorporates state-of-the-art cellular models, Ekaterinburg--Oxford (EO) model or ten Tusscher--Noble--Noble--Panfilov (TNNP). Ventricular mechanical activity on the...
Conference Paper
Full-text available
Nowadays, the sizes of image collections are increasing dramatically and reaching petabytes of data. Such large volumes cannot be analyzed on personal computer within a reasonable time. Therefore, processing of modern image collections requires distributed computing. This paper presents a MapRe-duce Image Processing framework (MIPr), which provides...

The approach to build territorial distributed storage system for high performance computing environment of UB RAS is presented. The storage system is based on the dCache middleware from the European Middleware Initiative project. The first milestone of distributed storage system implementation includes the data centers at the two UB RAS Regions: Ye...

Project
The project is aimed at creating algorithms for modern high-tech implantable low-voltage pacemakers (cardioverters). The basis of their effectiveness is the phenomenon of induced drift of spiral waves, which arise during arrhythmias, with the help of a series of weak electric impulses. Such electrotherapy saves the lives of patients during ventricular tachycardia and is much more gentle and easily tolerated than traditional shock defibrillation-cardioversion.
