High Energy Diffraction Microscopy (HEDM) delivers in-situ microstructural information from the bulk of polycrystalline materials. This talk will describe the MIDAS package, developed at Advanced Photon Source (APS), for real-time reconstructions of HEDM data for both "near-field"(NF-) and "far-field"(FF-) HEDM. This is aimed towards providing feedback for the user, which can help drive experiments and make data reduction process more user-friendly. Using a combination of HPC and GPU resources, MIDAS can provide turnaround times of the order of minutes for both NF- and FF-HEDM data sets. We will demonstrate recently developed computational strategies to push the limits of the HEDM technique to enable true bulk measurements for small-grained and deformed specimens.
