The distributed computing system of the ATLAS experiment at LHC is allowed to opportunistically use resources at the Czech national HPC center IT4Innovations in Ostrava. The jobs are submitted via an ARC Compute Element (ARC-CE) installed at the grid site in Prague. Scripts and input files are shared between the ARC-CE and a shared file system located at the HPC centre via sshfs. This basic submission system has worked there since the end of 2017. Several improvements were made to increase the amount of resource that ATLAS can use. As a result of the improvements, the utilisation of the Czech national HPC center by the ATLAS distributed computing increased.
