The unshuffle of a deflated + shuffled chunk (a panel-table HDF5 run: 8.4 MB per frame) moved one byte at a time with the pixel size read at run time, and wrote the whole frame before it was converted. It now assembles each 2- or 4-byte pixel from its byte planes in a loop the compiler vectorises, a 128 kB piece at a time, and each piece is converted into the image while it is in the cache, as for an unshuffled chunk. Bit-identical: the FNV pixel hashes of 2000 frames on the five reader configurations are unchanged. Reader alone on the panel-table run, 16 threads, 2000 frames: the unshuffle went from 58% of the reader's cycles to 13%; wall 7.7-8.6 -> 5.1-7.0 s on a loaded machine.

Jungfraujoch
Application to receive and analyse data from the PSI JUNGFRAU and EIGER detectors, together with
rugnux, its program for processing stored diffraction data - rotation and serial, macromolecular
and small-molecule - from images to merged reflections.
