The virtualized XPCS acquisition and analysis workflow system in use at the APS. These components are loosely connected via a well defined HDF5 file interface and a message-based workflow pipeline. (1) The detector data acquisition system writes data directly to a parallel file system located at the APS. (2) The workflow pipeline automatically transfers data from the APS to the Magellan resource over 2 × 10 Gb s−1 network links. (3) The Hadoop MapReduce-based autocorrelation job and subsequent fitting routines are run on the Magellan resource. (4) Reduced data are automatically transferred back to the APS. (5) The user views output visualizations and may adjust experiment parameters for subsequent acquisitions.
