Description

The ClimateMachine kernels often specify the ndrange as an integer multiple of the workgroup, e.g.:
https://github.com/CliMA/ClimateMachine.jl/blob/feacd0238343cdf268ae660e56b301f487689efc/src/Numerics/DGMethods/DGModel.jl#L1241-L1242

In this case, it would be simpler to be able to specify something like ngroups=info.nrealelem

Research direction

Start with the ndrange handling used by the kernel API and compare it with the referenced src/Numerics/DGMethods/DGModel.jl lines 1241-1242. The work is complete when callers can specify ngroups=info.nrealelem as an alternative to an integer-multiple ndrange.
