Performance optimization of BLAS algorithms with band matrices for RISC-V processors
Anna Pirova, Anastasia Vodeneeva, Konstantin Kovalev +5
The rapid development of RISC-V instruction set architecture presents new opportunities and challenges for software developers. Is it sufficient to simply recompile high-performanc…
Case Study for Running Memory-Bound Kernels on RISC-V CPUs
Valentin Volokitin, Evgeny Kozinov, Valentina Kustikova +2
The emergence of a new, open, and free instruction set architecture, RISC-V, has heralded a new era in microprocessor architectures. Starting with low-power, low-performance protot…
Simulating quantum dynamics: Evolution of algorithms in the HPC context
I. Meyerov, A. Liniov, M. Ivanchenko +1
Due to complexity of the systems and processes it addresses, the development of computational quantum physics is influenced by the progress in computing technology. Here we overvie…
Transforming the Lindblad Equation into a System of Linear Equations: Performance Optimization and Parallelization of an Algorithm
Iosif Meyerov, Evgeny Kozinov, Alexey Liniov +4
With their constantly increasing peak performance and memory capacity, modern supercomputers offer new perspectives on numerical studies of open many-body quantum systems. These sy…
Propagating large open quantum systems towards their steady states: cluster implementation of the time-evolving block decimation scheme
Valentin Volokitin, Ihor Vakulchyk, Evgeny Kozinov +5
Many-body quantum systems are subjected to the Curse of Dimensionality: The dimension of the Hilbert space , where these systems live in, grows exponentially with syst…
Unfolding quantum master equation into a system of real-valued equations: computationally effective expansion over the basis of generators
A. Liniov, I. Meyerov, E. Kozinov +4
Dynamics of an open -state quantum system is typically modeled with a Markovian master equation describing the evolution of the system's density operator. By using generators of…
Quantum bifurcation diagrams
M. Ivanchenko, E. Kozinov, V. Volokitin +3
Asymptotic state of an open quantum system can undergo qualitative changes upon small variation of system parameters. We demonstrate it that such 'quantum bifurcations' can be appr…
Computation of the asymptotic states of modulated open quantum systems with a numerically exact realization of the quantum trajectory method
V. Volokitin, A. Liniov, I. Meyerov +4
Quantum systems out of equilibrium are presently a subject of active research, both in theoretical and experimental domains. In this work we consider time-periodically modulated qu…
