But I remember clearly I saw photos, 17R is being used for take-offs, 17L planes landing at the same time. Maybe someone else can help. This was at least few years back when runway 5 wasn't used at the current rate.

I was on board multiple times for both parallel operations you are mentioning. The case TK787 mentioned is still used during strong southern wind bad weather conditions.
However parallel takeoffs mentioned by THY784i is no more used (to my knowledge), after an incident which both planes started running together at the same time on 35L and 35R. This was also on the news at that time. It was said that, tower had ordered to turn separate directions just after take off to avoid a collusions. There were also jokes about who took off first (like a drag race). Even someone claimed that B737 was the winner against A319 (if I remember well the types).
