* Missed one file in last commit * tweaks for CPU compilation * In OpenACC: allocating types as well as data components in ACC copyins, deletes * Ignoring things for Luis... * Missing statement * Aligning array sizes in kernels with arguments * Refined argument intents for some kernels * Workaround for PGI compiler problem with logicals * Input sanitizing gets it own module * Yeah, we'll need the sanitizing module too. * OpenACC-compatible checking for max and min values * OpenACC value checking working; OLCF makefile doesn't use managed memory * Logical kind chosen with pre-preprocessor flags
-- Several small bug fixes (argument intent, maximum interpolation indices, thanks to Sebastian Rast) -- Parameterized checking for out-of-range values (works also on GPU) -- Continuous integration with Travis (thanks to Valentin Clement) -- Logical type defaults to Fortran; can be set to use c_bool with -DUSE_CBOOL -- Internal build system can use environmental variables instead of specified files (Makefile.conf etc.) to define compilers, flags, choose kernel directory -- Python scripts to automate running and testing of RFMIP examples -- Update RFMIP examples to use version 1.2 of atmospheres file -- End-to-end RFMIP examples on GPU are broken; fixes pending
Remove nullify statements on declaration of pointers in subroutines to ensure thread safety for mo_gas_optics_rrtmgp. When pointers get assigned in declarations, they implicitly get a save attribute and are assumed static. This is a problem when then occurs in a threaded region, so this code was NOT thread-safe before. Removing the `=> NULL()` does not change the behavior of the code for non-threaded applications, but does ensure thread-safety.

* Shortwave RFMIP running end-to-end on GPU. Boundary conditions still on CPU. * Upper boundary condition lives on GPU in LW no-scattering calculation. * Moved optical props validation in rte_lw(); simplified data movement in gas optics. Source function still sloshing back and forth between host and device. * Surface emissivity computed on GPU in LW RFMIP example * Moved transposition of surface Planck source onto GPU, clumsily; LW RFMIP cases now running end-to-end on device. * RFMIP boundary conditions on GPU; removing async (may add back later) * Reorder kernels use a single source * Moving array-zeroing routines into mo_util_array * Single-source for array utilities * rte_sw uses array utilities to check validity of boundary conditions * Adding 1D array-zeroing routine * Some SW RFMIP boundary conditions on GPU. * Single-source for fluxes_broadband_kernels * Removing an unneeded OpenACC data transfer * Array value checking uses functions in mo_rte_lw; syntactic cleanup * Correcting mal-formed Makefile * Refined copying of one array in SW examples. * Ben Hillman spots a GPU array being initialized on the CPU. Fixed that.
Contributions from Dmitry Alexeev from Nvidia. Dramatically improves performance of clear-sky RFMIP standalone cases on GPUs. Fixes compiler bug in PGI related to private local variables. * tiling reorder, could still be improved by about 40% * using kernels in the mo_util_array, faster and more compact * constant shouldn't be explicitly allocated * tile combine_and_reorder, almost full bandwidth now * process several elements per thread in expensive kernels * fix interpolation, use gang vector * add another kernel for optical_depths_minor, only working in a special case (hopefully typical case). about 3x faster. * avoid atomics in sum_broadband, 2.5x faster * explicitly make private arrays stay in global memory, fixed possible errors and 8x faster due to collapsed loop * fuse lw_source_noscat into lw_solver_noscat, faster by about 1ms on Piz Daint * fixed subscript typo in denom * fix out-of-bounds issue * added comments about how the reorder kernels work * introduce point-wise lw_source_noscat_stencil to express concepts separation while keeping fused loops * added comments explaining bug workaround for adding routine * fixed unrolled loop bounds and added comments * removed unused variable * added missing data deletion * remove the default kernel in gas_optical_depths_minor, the optimized kernel can deal with variable number of g-points per band now

…PUs during calculations (#53) Should be more tightly integrated with host models already running on the GPU.

Use environment.yml file to detail Python packages needed for testing and validation/verification, to be obtained from conda.
Changes a single array from assumed-size to assumed-shape.
Move CI file from Owncloud to LDEO; resolution-independent RCEMIP profiles.
More substantive content in the Jekyll pages, RTE kernels in-line documentation complete
… and no2 aren't included in the list of gases in these focing scenarios but they're needed to initialize the gas concentrations. Other approaches might be more robust.
* fix(doc): upgrade CI environment, use newer version of ruby
* Jekyll pages following Diataxis framework * Streamlined FORD pages, updates to FORD boilerplate Co-authored-by: Brad Richardson <everythingfunctional@protonmail.com>
