Hi tera,

      Ya I got it... Thanks

      When running a cuda program in GT 240, I got the same time generation as GTX 460.

      I generate time in both GT 240 and GTX 460 program.

      Is it correct ? or I have to change any properties inside the program ?

      See the attached file to check my program.
