We explore the possibilities of using neural networks to study phase transitions. The main question is the level of accuracy which can be achieved for the estimates of the critical point and critical exponents of statistical physics models. We generate data for two spin models in two dimensions for which analytical solutions exist, the Ising ...

We study the dimensional crossover of polarized superfluids. Employing large-scale numerical simulations the attractive Hubbard on multi-leg ladders with up to five legs, we construct ground-state phase diagrams which feature polarized (Fulde-Ferrell-Larkin-Ovchinnikov like) and unpolarized (Bardeen-Cooper-Schrieffer like) phases and trace the crossover from strictly one-dimensional behavior to higher dimensions. We pay special attention to the ...

Particle-in-Cell models are among the most demanding computational problems that require appropriate supercomputing hardware. In this paper we consider the solution of generic PIC problems on the Desmos supercomputer equipped with novel AMD MI50 GPUs and Angara interconnect. The open-source PIConGPU code is used. The acceleration limits and bottlenecks for this type of calculations are ...

Modern supercomputers consist of thousands of GPUs interconnected by high-speed HPC fabric. Angara interconnect supports Remote Direct Memory Access (RDMA) semantic, hence making it promising fabric solution for GPU-based supercomputers with a large amount of high-bandwidth RAM. Within this work we extend Angara interconnect low-level API allowing one transparently register (pin) GPU and user-space memory, ...

We studied the performance of two algorithms for processing results of molecular dynamics (MD) simulation on modern computing platforms: calculations of radial distribution function (RDF) and energies. We found that both algorithms effectively parallelize both on systems with shared memory and on clusters with distributed memory. For processing the results of medium-sized MD systems, the parallelization efficiency of ...

There has been a growing interest in defining models of automata enriched with time, such as finite automata extended with clocks (timed automata). In this paper, we study deterministic timed finite state machines (TFSMs), i.e., finite state machines with a single clock, timed guards and timeouts which transduce timed input words into timed output words. ...

In the fusion community, the use of high performance computing (HPC) has been mostly dominated by heavy-duty plasma simulations, such as those based on particle-in-cell and gyrokinetic codes. However, there has been a growing interest in applying machine learning for knowledge discovery on top of large amounts of experimental data collected from fusion devices. In ...

We formulate some term rewriting systems in which the number of computation steps is finite for each output, but this number cannot be bounded by a provably total computable function in Peano arithmetic PA. Thus, the termination of such systems is unprovable in PA. These systems are derived from an independent combinatorial result known as the Worm ...
