user31665: As far as I have read, I haven’t found a parallel algorithm to speed up Bitcoin mining. Are there any techniques that involve parallel or distributed algorithms, architectures that speed up Bitcoin mining ?

user5406: The atomic operation of Bitcoin mining is determining if a block candidate resolves to a hash that fulfils the required difficulty. This operation is so simple, that it is being performed about 700 quadrillion times per second. 
Since mining is a random process, there is no progress towards a block. It just succeeds whenever a block candidate turns out to be a valid block. Therefore, beyond making sure that every participant in a mining pool is checking different block candidates, there is no collaboration on mining.
