In numerical simulation of quantum chromodynamics the presence of large number of integration variables requires up-to-date hardware technologies, and software developed for the particular hardware. Due to the locality in field theory the main source of performance improvement nowadays is parallelization and simulation on GPU clusters. We present the GPU cluster at the Eotvos Lorand University. We briefly review the Krylov-Schur algorithm (which we use for matrix diagonalization and matrix function computation) and compare the performance of the GPU and parallel CPU implementation.
