Hi,
I have a small problem with cudaPrintfDisplay and cuda 1.1. Should cudaPrintfInit be called everytime after a cudaPrintfDisplay? If I call the same kernel twice and did a cudaPrintfDisplay without cudaPrintfInit as shown below, I get only the first display. If I add cudaPrintfInit before the second display call it works as expected. But I read that the init is to be called once unless one wants to increase buffer size, so I am confused.
#include "cuPrintf.cu"
__global__
void testKernel(int val) {
cuPrintf ("Value is:% d \n", val);
}
int main () {
cudaPrintfInit ();
testKernel <<< 2, 3 >>> (10);
cudaPrintfDisplay (stdout, true);
printf("===============\n");
testKernel <<< 2, 3 >>> (10);
cudaPrintfDisplay (stdout, true);
cudaPrintfEnd ();
return 0;
}
Thanks.
