Description
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.
