As others have noted, memory, I/O, and CPU-CPU communications (e.g. message passing) could all benefit from an explicit async model (I believe).

In this case SMT would help much because the core-units are can process other
threads streams when a I/O-access takes place. But I think this isn't necessary
for usual I/O on disk-controllers or NICs but for accesses to GPUs. These take
place with a much higher frequency.
