What makes you think this would be easier to parallelize than a traditional application? Just because there is only one kind of instruction used doesn't mean they don't still have to come in the right order!
I don't see any material online indicating that programs written for one-instruction-set-computers are more parallelizable than programs written for traditional computers. In fact, here is someone claiming the opposite:
> The disadvantage of an MISC is that instructions tend to have more sequential dependencies, reducing overall instruction-level parallelism.
