- FFTIndexerGPU makes and transforms the projection histograms FFT_BATCH_DIRECTIONS (4096) directions at a time, into one set of batch buffers, and keeps only the transposed magnitudes of all directions for the peak search, which still runs once over all of them. cuFFT's R2C gives the same bits at any batch count (checked at histogram lengths 1024-12568 and batches 1-16384), and every other step is per direction, so the result does not change. Measured: the two indexers of a first pass hold 0.83 instead of 2.48 GB, plus a quarter of the plan work area (0.2 instead of 0.8 GB each at a doubled cell bound). - Rugnux::GPUWorkersPerCard: the per-image loop's existing rule (24 bytes a detector pixel, half of the card's total memory) as one function, now also capping the first pass's spot-finding workers and the pre-scan's workers (both at most 8 a card as before). No change on a 16 GB or an 8.55 GB card with a 16-18 Mpx detector; a 4-6 GB card gets 4-6 of them. Output unchanged: p.hkl byte-identical on cytc_x10sa, myob_x10sa, 4nwv and 8qaw, on the RTX 5080 and with its total read as 8.55 GB. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

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.
