It is possible but the algorithm was specifically made for making this prohibitive.
See :
http://www.tarsnap.com/scrypt.htmlI think one what's slowing it down the most is latency to access large pool of memory.
On modern hardware and with default parameters, the cost of cracking the password on a file encrypted by scrypt enc is approximately 100 billion times more than the cost of cracking the same password on a file encrypted by openssl enc; this means that a five-character password using scrypt is stronger than a ten-character password using openssl.
