# Me later...
# The execution context is needed as graph memory allocation can cross 
# boundaries...
# So for the moment keep this in a separate branch

# Other TODO: perform prefetch and usage hints on Unified memory

# TODO: put CUDA backend behind a feature flag
# TODO: fix the SYCL bug and have CUDA and SYCL backend coexisting in the same
# project ;D
# TODO: Add an ExecutionContext class for device capability query
# for the moment have something like ExecutionContext::DisplaySpecs()
# and give the name of the backend, driver version, CPU or GPU
# etc...
