Computing for Large Hadron Collider experiments is based on the idea of distributed computing in centers located all around the world. Supporting computing centers were mostly adjusted for needs of the Worldwide LHC Computing Grid (WLCG). The existing capacities were extended by large supercomputing centers in the USA and Europe. We will describe different obstacles which we had to resolve to be able to use these HPC centers effectively. The examples will be based on the experience of the ATLAS experiment, which is the most CPU consuming project in the WLCG. We will discuss software installation in the relatively close environment of HPC centers, experience with different CPU architectures and procedures to effectively run jobs on systems with many cores.
