This presentation will describe work that has been done to make NERSC Cray systems friendlier to data intensive workflows in anticipation of the availability of the NERSC-8 system this Autumn. Using shifter, a docker-like container technology developed at NERSC by Doug Jacobsen and Shane Canon, the process of delivering software stacks to Cray compute nodes has been greatly simplified. Some detail will be given to describe the method used to deliver CVMFS to the Cray compute nodes using shifter. We found unexpected increases in metadata performance though the use of image file systems. Results of tests with ATLAS G4 simulations and Analysis Software on the Cray XC30 system, edison, will be presented.
