AT&T leverages Argonne’s datasets and expertise

To take advantage of the cloud's flexible computing power without exposing that information, the Argonne team essentially warps, or "perturbs," the model and data being sent for calculations, changing key variables and equations. A disguised version of the problem goes to a cloud-based "solver" computer, and the answer is returned to a local, secure server for decoding. (Image by Argonne National Laboratory.)
