    First Brook call is sloooooooowww

    BarsMonster

      Hi, I've got excellent performance of my application on Brook platform, but very first brook kernel takes ~4000ms.

      kernel function itself have around 25 streams, and amount of data transferred each call is around 1Mb. 2nd and later calls are fast & perfect (~90ms).

      Any clues?

      Right now I have to measure performance of my application, so I have to do first "dummy" call , and bench second :-S
