All-sky example useful for timing

[RobertPincus]

Revises the all-sky example to be useful for timing benchmarks. The atmospheric profile more-or-less follows the profile for RCEMIP at a surface temperature of 300 K. Users specify the number of columns and layers and may choose more than a single iteration. (Array checks are turned off for all but the first iteration). A k-distribution must be specified. Clouds are optional, and occupy 2/3 of columns; aerosols in every other column are optional but require clouds.

A netCDF file is produced; small files of {LW,SW}x{clouds, clouds+aerosols} are used for verification during continuous integration. Timing output is simple, i.e.

ncol   nlay   ngpt  clouds aerosols time_per_col_ms nloops time_total_s time_min_s
     2     32    128       0        0           0.978     24        0.047      0.047

Addresses #128

Also: removes use of NCHOME environment variable, removes (optional) use of GPTL timing library in RFMIP examples.

Design is great, tools works well. Compile and test sequence fails on my workstation because files are not adequately copied to reference in allsky test:

FileNotFoundError: [Errno 2] No such file or directory: '/home/chiel/devel/rte-rrtmgp/rrtmgp-data/examples/all-sky/reference/rrtmgp-allsky-lw-no-aerosols.nc'
make[1]: *** [Makefile:61: check] Error 1
make[1]: Leaving directory '/home/chiel/devel/rte-rrtmgp/examples/all-sky'

I only have a rrtmgp-allsky-no-aerosols.nc

@Chiil Thanks for the feedback. Did you check out branch feature-timing of the data repo as well?

I use the default branch of the data, I merged the test into my cuda branch.On 2 Jul 2023, at 01:37, Robert Pincus ***@***.***> wrote: @Chiil Thanks for the feedback.

@Chiil If you check out the feature-timing branch of the data repo, do you find all the data there that enables you to run the tests?

[Chiil]

RFMIP and all-sky test pass, flexible configurations work. Code can be merged to develop.
