- otherwise it doesn't compile without linking to COBALT due to COBALT interface updates.

* Add MOM_ANN module * Mesoscale momentum parameterization with ANN - Computes subgrid stress using ANN in MOM_Zanna_Bolton - Uses MOM_ANN module for ANN inference Equivalent MOM_override for defaults ``` USE_ZB2020 = True ZB2020_USE_ANN = True USE_CIRCULATION_IN_HORVISC = True ZB2020_ANN_FILE_TALL = /path/to/ocean3d/subfilter/FGR3/EXP1/model/Tall.nc ``` * Mesoscale momentum parameterization with ANN (#2) Blank commit after squash/rebase was handled on command line * Moved MOM_ANN.F90 to src/framework/ * Minor refactor of MOM_ANN - Removed unused modules - Removed unused MOM_memory.h - Added input and output means which default to 0 and do not need to be present in the weights file - Gave defaults to means, norms, tests so that they do no need to be present in file - Added missing array notation "(:)" - Minor formatting * Adds unit tests and timing test to MOM_ANN - Added ANN_allocate, set_layer, set_input_normalization, and set_output_normalization methods to allow reconfiguration during unit tests - Added ANN_unit_tests with some simple constructed-by-code networks with known solutions - Added config_src/drivers/unit_tests/test_MOM_ANN.F90 to drive unit tests - Added config_src/drivers/timing_tests/time_MOM_ANN.F90 as rudimentary for timing inference * Adding multiple forms of inference - Adds inference operating on array (instead of single vector of features) - Implements several different versions of inference with various loop orders - Involves storing the transpose of A in the type - Tested by checking inference on same inputs is identical between variants - Added randomizers to assist in unit testing - Adds timing of variants to config_src/drivers/timing/time_MOM_ANN.F90 - Adds an interface (MOM_apply) to select preferred version of inference subroutine - Added command line args to time_MOM_ANN.F90 to allow more rapid evaluation of performance Variants explored, timed with gfortran (13.2) -O3 on Xeon: - vector_v1: - original inference from Pavel - vector_v2: - allocate work arrays just once, using widest layer - loop over layers in 2's to avoid pointer calculations and copies - speed up, x0.8 relative to v1 - vector_v3: - transpose loops - slow down, x1.54 relative to v1 - vector_v4: - transpose weights with same loop order as v1 - slow down, x1.03 relative to v1 - array_v1: - same structure as v2, working on x(space,feature) input/outputs - speed up, x0.41 relative to v1 - array_v2: - as for array_v1 but with transposed loop order - apply activation function on vector of first index while in cache - speed up, x0.35 relative to v1 - array_v3: - same structure as v2, working on x(feature,space) input/outputs - speed up, x0.58 relative to v1 * Renamed ANN variants and added some module documentation - Added module dox - Renamed _v1, _v2 etc to labels - Added ANN_apply_array_sio to ANN_apply interface - Replaced "flops" with "MBps" in timing output * Removed alternative variants of ANN in favor of optimized - Deleted variants of ANN that did not perform as well as the two versions that remain. * Apply array_sio function in ANN inference for momentum fluxes (#5) * Apply array_sio ANN inference for computation of momentum fluxes * remove trailing space * Initial commit * address Robert Hallberg code review * Restore deafult value of ZB_SCALING coefficient --------- Co-authored-by: Alistair Adcroft <Alistair.Adcroft@noaa.gov> Co-authored-by: Alistair Adcroft <adcroft@users.noreply.github.com>
