Parallel SION file output currently not possible when using CUDA to communicate.
When the virtual cluster is built on CUDA you cannot write out parallel SION files. Not really a problem as most nodes will at most have in the 10s of GPUs. We should think about implementing this at some point though.

Add a warning if a parallel write is requested -
Ignore user request and do serial write instead
