No such thing as a 'protocol' for SHA3. SHA3 is not a 'protocol'. It is an algorithm, a standard maybe, not a 'protocol'. Usually 'protocols' involve the language used by two peers to communicate.
SHA2 is very mildly parallel as far as I remember. SHA3 possibly even less so (I looked at it for about 2 minutes).
You're confusing properties of the hash with properties of the PoW 'scanhash' function. The latter is embarrassingly parallel by definition, the former is not.
All PoW scanhash functions are embarrassingly parallel, whatever this parallelism can be exploited is another business. For SHA3, there's basically no problem in SHA3 itself. So yes, you can compute multiple hashes in parallel. That makes scanhash faster, Keccak is just as fast as previously.
