Warp engine and Simple engine

User 67 | 3/14/2014, 10:54:53 AM


I considered running page rank with warp engine and without warp engine as given in demoapps tool kits. I observed that simplepagerank runs in around 9 sec while warpengine_pagerank completes at around 18 sec. But the documentation says performance is not disturbed when we use warp engine. I am confused. Please help.

Thanks and Regards, Sagar

Maybe, one reason is that simplepagerank uses float while warpengine_pagerank uses double.
