ArWen 2.9.6

ArWen 2.9.6. The desktop stays ArWen Desktop 1.0.10, from the 2.9.0 release.

• Install or upgrade: pip install --upgrade "gpuwm[all-cu12]==2.9.6".
• Integration kit, verification records, and checksums.
• Node GPU gate: Stage 1 and both GPU-shard results, with the tested source revision and card identity.

New

• Soundings at any point after a run: gpuwm soundings RUN --columns DIR writes a column store of every column at each history time, and a sounding drawn from a stored column matches one drawn from the history file.
• Soundings say what they show: the point, valid time, forecast hour and member at the top left, and the model and its start in bold at the top right (title, brand and init settings, or GPUWM_SOUNDINGS_SETTINGS). rw_hex_points takes --brand.
• Single-domain runs apply [perturbation] warm bubbles.
• gpuwm hydro ahead CONFIG builds a domain's hydro fabric before the launch that uses it.

Fixed

• gpuwm go no longer waits about 35 minutes on a RAP or HRRR native cycle that has already posted.
• HRRR and RAP smoke starts before 2021-12-21 14Z read MASSDEN in its real units (ug m-3).
• Morrison microphysics (mp=10) steps about 11% faster, with identical output.
• The end-of-run redraw of a fire (SFIRE) forecast no longer fails on the native fire panels, and those panels keep their folders.
• A WRF-input --restart started from another directory is no longer refused as a different run.
• Preparation has no single-core stages between fetch and forecast, and a forecast from a prepared bundle pre-warms its kernels.
• rw_soundings reads only the profile columns it needs (much faster, a quarter of the memory) and no longer hangs at exit.
• A fetch that streams many files at once no longer uses up the account's file watchers (other programs then failed with "too many open files").
• Maps: threshold colorbars (snowfall, liquid equivalent) give every band the same length with a tick at each boundary; a map with nothing to draw says why; rain, snow, freezing rain and ice pellet flags are drawn as two categories with crisp edges; dimensionless fields carry no unit label; the map frame is the same width on every side.
