c - Intel based hardware speed ups for DCT? -

we writing image processing algorithm targeting intel hardware. prefer generic c implementations, have identified algorithm @ core ton of discrete cosine transforms (dct's) works extremely well. unfortunately, our throughput requirements such generic c implementation 2 orders of magnitude slow. can 1 order of magnitude through other tricks, if can improve dct's order of magnitude have path towards success.

is intel mmx way @ hardware acceleration these dct's? there other intel specific libraries and/or hardware can exploit speed these bad boys up?

where start look? new job me, , first time digging hard intel hardware, pointers appreciated.

take @ intel's integrated performance primitives library. contains wealth of routines optimized heavily take utilize of intel architecture, mmx , sse. among many other things, ipp contains routines dct (documentation here).

How do I check if an insert was successful with MySQLdb in Python? -

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
