i have problem that on CPU it gives right results. but if run my code on GPU it return random results.

i pinpoint that problem is in this function. event_vector array did not contain proper values.

you can find whole code here;a=blob;f=kernels/;h=95f69b0872a356b035bc6200851cd7da1bdc3713;hb=da36c88bdc666c12c8fe5131a6c59ca8e48eae30
