Modern supercomputers use GPUs as accelerators in computing nodes. GPUs allow scientific applications to greatly boost performance using fine-grained parallelism. CUDA programming model oriented to take advantage of the SIMT GPU architecture writing low-level code. Contrary to this approach, OpenACC and OpenMP 4.5 represent a declarative model of parallel programming using compiler pragmas with support ...

The population annealing algorithm is a novel approach to study systems with rough free-energy landscapes, such as spin glasses. It combines the power of simulated annealing, Boltzmann weighted differential reproduction and sequential Monte Carlo process to bring the population of replicas to the equilibrium even in the low-temperature region. Moreover, it provides a very good ...

Population annealing is a promising recent approach for Monte Carlo simulations in statistical physics, in particular for the simulation of systems with complex free-energy landscapes. It is a hybrid method, combining importance sampling through Markov chains with elements of sequential Monte Carlo in the form of population control. While it appears to provide algorithmic capabilities ...

By the example of the RNGAVXLIB random number generator library, this paper considers some approaches to employing AVX vectorization for calculation speedup. The RNGAVXLIB library contains AVX implementations of modern generators and the routines allowing one to initialize up to 10^19 independent ran-dom number streams. The AVX implementations yield exactly the same pseudorandom sequences as ...

Рассматривается задача поиска точек сдвига матожидания временного ряда большой длины. Предполагается, что длина ряда велика (от миллиона элементов), и его анализ будет производиться на суперкомпьютере, в связи с чем возникает необходимость разработки соответствующего параллельного алгоритма.

Historically, a typical embedded system has been designed as a control-dominated system using only a state-oriented model, such as FSMs. However, the trend in embedded systems design in recent years has been towards highly distributed architectures with support for concurrency, data and control flow, and scalable distributed computations. This implies that a different approach is ...
