Popis:	The statistical language R and Bioconductor package arefavoured by many biostatisticians for processing microarraydata. The amount of data produced by these analyses hasreached the limits of many common bioinformatics computinginfrastructures. High Performance Computing (HPC)systems offer a solution to this issue. The Simple Parallel RINTerface (SPRINT) is a package that provides biostatisticianswith easy access to HPC systems and allows the additionof parallelized functions to R. This paper will presenthow we added a parallelized permutation testing functionin R using SPRINT and how this function performs on asupercomputer for executions of up to 512 processes.
