leonarski_f	46ad2c10ed	Refinement GPU: the robust scale fit on the card, the pool back in every trial slot ... The score's robust fine pass (pseudo-Huber IRLS of ModelScaleBox::robust) on the device, so that refinement on a GPU no longer fits its scale on the host every cycle - with the trials side by side that was a robust grid search on one thread per slot (13-133 s per refinement on the seven timing sets, against 1.7-8 s before the score commit). - ModelScaleGPU: the weights multiply the WSSR and J^T J / J^T r in scale_sums (a weight row per fit, reserved at the first robust fit); robust_residuals / robust_weights kernels; the median of each fit's first residuals taken on the host as FitModelScale takes it (nth_element at n/2, on the fits' threads); LevMarBatch split out of FitBatch so that the rounds restart from where a fit stands. FitSolvent(..., robust) refits the coarse winner in the fine pass, as FitModelScale's robust fit does; the plain fit is unchanged. - ModelScaleGPUPool::Fit(..., robust); its streams at the highest priority: a fit is a chain of small launches the host waits on, and on a card shared with the trials' long kernels each wait queued behind them (refit.scale 58-87 ms -> 14-45 ms per cycle, the result the same to the bit). - Refinement: the main context and every trial slot fit on their pool (robust); the CPU engine keeps FitModelScale's robust fit. The card's fit is FitModelScale's to rounding (float residuals and weights, the steps' anisotropic factor in float), deterministic run to run and whichever engine a fit takes: R-work/R-free of the 14 parity sets on the GPU equal the CPU engine's to 4 digits (largest difference 1.4e-6 on the 3.6 A set). Test: ModelScaleGPUPool_RobustMatchesFitModelScale (one reflection in fifty a 4x outlier, five cells).

leonarski_f	c4d2d419ce	Refinement score: the model's structure factors as REFMAC 5.8 scores them at 0 cycles ... Three terms of the score of a model - the same F_model at every stage, the as-given start and the refined end alike - and a breakdown of it: - Riding hydrogens from the start: the dictionary's hydrogens are added before the model is first scored (REFMAC's 0-cycle restores them; they move R by 0.010-0.013 at 1.1 A). The engine is made once, with them. - The bulk-solvent mask on a grid of its own, min(d_min/3, 0.4 A), at most 2^26 points. On the density grid (1.1 A at 3.3 A) gemmi's 0.8 A shrink found no grid offset and was skipped, which put R 0.015-0.03 high at >= 2.5 A. 0.3 and 0.4 A agree to 0.001. - The overall scale and anisotropic B by robust least squares (pseudo-Huber, iteratively reweighted, c = median |residual|) in the fine pass of the k_sol/b_sol grid (ModelScaleBox::robust, refinement only; MR and validation keep the plain fit). Plain least squares on |F| is the exact LS optimum but lets a few badly-fitted strong reflections set the scale (1.1 A set: R 0.1706 against REFMAC's 0.1600). The scale fit of refinement now runs on the CPU (no ModelScaleGPUPool). RefinementSettings::score_only scores the model as given and stops; RefinementResult::score_start carries every term (k, B, anisotropic B, k_sol, b_sol, mask spacing, R in 20 shells, -lnL work/free, the likelihood FOM, hydrogens; per-reflection terms with score_only). GeometryStatistics gains rmsZ. rugnux_refine_test: --score-only, --dump. Measured against REFMAC 5.8.0431 ncyc 0 (refi bref iso) on the same model, data and flags, 14 open-arm sets 1.1-3.6 A: R-work/R-free within 0.002 on 12 (was +0.003..+0.03); 7n2s and 9yl4 score 0.003/0.005 below REFMAC, which a 0.6-0.8 A mask grid reproduces. REFMAC with ANISOU stripped scores identically, so isotropic B is not a parity term. Open: the likelihood's D/FOM (ours 0.01-0.11 higher at high resolution); geometry differs only by REFMAC's metal LINK restraints and residues outside the embedded dictionary.

leonarski_f	8261b7354e	v1.0.0-rc.176 (#86) ... * jfjoch_broker: Optional live Rugnux analysis of DECTRIS rotation collections inside the broker, with merged data, maps and the placed model written beside the master file, the rotation lattice in the scan result, and a "Rugnux live" tab and dashboard row in the web frontend. * Rugnux: Faster processing, with molecular replacement and model validation spread over several GPUs and run on the Apple GPU on macOS. * Rugnux: The polarization stated in miniCBF and d*TREK headers is used, twinned crystals' space groups are decided more reliably, and a run that finds no lattice still reports every image.

leonarski_fandFilip Leonarski	19b135186d	v1.0.0-rc.175 (#85) ... * Rugnux: Processes a collection live while jfjoch_broker writes it (`rugnux <master.h5> <broker URL>`). * Rugnux: Processing starts on the first images and confirms its choices once all are in, so analysis can begin during collection. * Rugnux: Faster processing, especially on servers with several GPUs and CPU sockets and on computers without a GPU (`--no-gpu`, macOS). * Rugnux: Uses much less GPU memory, so large data sets stay on the GPU of smaller cards, and a data set too large for the card is processed on the CPU instead. * Rugnux: On macOS, Bragg integration runs on the Apple GPU. * Rugnux: Better handling of twinning and pseudo-symmetry, with the twin hypothesis written as `<prefix>_twin_<SG>.mtz`, and a wrong `--model` no longer confirms the data or decides the hand. * Rugnux: `--model` accepts predicted (AlphaFold) models and falls back to molecular replacement when the model is not placed as a rigid body (experimental `--mr` forces it), settling space group, hand and twinning and writing a different answer as `<prefix>_mr.mtz`. * Rugnux: Molecular replacement is faster and settles the space group in more cases with several copies in the asymmetric unit. * Rugnux: Deposition-ready mmCIF, a richer report, and numbered steps on the terminal with the full log in `<prefix>_log.txt`; `_P1.mtz`, `--estimate-beam-center` and `--beam-center-search` are removed. * Rugnux: The beam-stop shadow is found correctly on tilted detectors. * Rugnux: Stills files that record a stationary goniometer axis get the default stills geometry refinement. * jfjoch_viewer: "Analyze dataset" uses the same defaults as a bare `rugnux <file>`, and shows the results of processed CBF, marCCD and SMV sweeps. * jfjoch_viewer: The Files panel refreshes on F5 and every few seconds, and the plot type and other selections stay put during live collection. * jfjoch_writer: Memory stays bounded and old data files are closed efficiently on long runs, any failure ends the run in an error state the broker is told about, and the master file appears only after its data files; the ZeroMQ pusher logs when a stalled writer makes it drop images. * Fixes: The TCP image pusher no longer blocks the broker's receiver, GPU out-of-memory failures stop with a clear message, and the XDS plugin masks module and chip edges. --------- Co-authored-by: Filip Leonarski <jungfrau@filips-mac-mini.home> Reviewed-on: #85 Co-authored-by: Filip Leonarski <filip.leonarski@psi.ch>	2026-10-16 15:34:43 +02:00
