Compile error (outdated alpaka, misplaced LLAMA_NO_HOST_ACC_WARNING) #80

When using CUDA 10, there are also the warnings, but the error below occurs on CUDA 9.2.88 and CUDA 10. It is the same bug as in llama. I try to fix it by updating it to the latest alpaka version, where it should be fixed. Maybe it will take some time, but our students need cupla soon.

ok, just updated to the backport 0.3.5 of alpaka and it seems to work again. Kudos to the backporters! :+1:

Glad this helped!
