ClimaComms.jl

ClimaComms.jl is a small package to work with diverse computing devices and environments (e.g., CPUs/GPUs, single-process/MPI). ClimaComms.jl provides objects to represent such devices and environments and functions to interact with them in a unified way. ClimaComms.jl is used extensively through the CliMA ecosystem to control where and how simulations are run (e.g., on one CPU, or on several GPUs using with MPI).

ClimaComms.jl supports the following Devices:

• CPUSingleThreaded
• CPUMultiThreaded (not actively used)
• CUDADevice and Contextes (i.e., environments for distributed computing):
• SingletonCommsContext
• MPICommsContext
