Application of CUDA technology to calculation of ground states of few-body nuclei by Feynman's continual integrals method

Mikhail A. Naumenko, Vyacheslav V. Samarin

Abstract


The possibility of application of modern parallel computing solutions to speed up the calculations of ground states of few-body nuclei by Feynman's continual integrals method has been investigated. These calculations may sometimes require large computational time, particularly in the case of systems with many degrees of freedom. This paper presents the results of application of general-purpose computing on graphics processing units (GPGPU). The energy and the square modulus of the wave function of the ground states of several few-body nuclei have been calculated using NVIDIA CUDA technology. The results show that the use of GPGPU significantly increases the speed of calculations.
