AB  - QCDGPU is an open-source tool for Monte Carlo lattice simulations of the SU(N) gluo- dynamics and O(N) models. In particular, the package allows to study vacuum thermo- dynamics in external chromomagnetic fields, spontaneous vacuum magnetization at high temperature in the SU(N) gluodynamics and other new phenomena. The QCDGPU code is implemented in the OpenCL environment and tested on different OpenCL-compatible devices. It supports single- and multi-GPU modes as well as GPU clusters. Also, the QCDGPU has a client-server part for distributed simulations over VPN. The core of Monte Carlo procedure is based on the PRNGCL library, which contains implementations of the most popular pseudorandom number generators. The package supports single-, mixed- and full double-precision including pseudorandom number generation. The current version of the QCDGPU is available onlin
