fast-resolve reconstructions of the 2052 MHz Cygnus A data. The left column displays snapshots of a fast-resolve reconstruction on an NVIDIA A100 GPU. The right column shows snapshots of a fast-resolve reconstruction on an NVIDIA RTX 390 GPU. Both reconstructions ran the same number of major and minor iterations. Since the reconstruction on the A100 GPU was finished after 22 min, the bottom left panel is identical to the row above. On the A100 GPU fast-resolve is approximately twice as fast as on a RTX 390 GPU, and 25 times faster than on the CPU displayed in Fig. B.1.
