Portable Cross-Facility Workflows for X-ray Ptychography
DescriptionWe describe portable software workflows for processing ptychography data from large-scale experimental facilities. The Advanced Photon Source (APS) and Linac Coherent Light Source (LCLS) are examples of facilities which generate large amounts of high-energy x-rays used for scientific research. Both facilities recently underwent upgrades that increased data output by orders-of-magnitude. The increased data rates necessitate a processing pipelines that provides timely feedback to beamline scientists and scientific users. X-ray ptychography, a data-intensive computational imaging technique, stands to benefit from robust software workflows that facilitate the use of large computing facilities. Here we describe a file-based workflow that can be deployed at any ptychography beamline. We detail its use during two experiments: the first reconstructed 98 experimental scans sent from APS to the Argonne Leadership Computing Facility (ALCF). The second experiment demonstrated cross-facility capabilities by reconstructing 15 experimental scans sent from users at the Linac Coherent Light Source (LCLS) to ALCF.
