why when I use brook+ 1.21 got a strange behavior, finally, I find it like below, when I try to use twice GPU:
/////////////////////////////////////////////////////////////////////////
// Brook code block
/////////////////////////////////////////////////////////////////////////
{
float inputStream<Length>;
float outputStream<Length>;
float res<1>;
streamRead(inputStream, input);
hello_brook_check(inputStream, outputStream, (float)Length / 3.0f);
hello_brook_sum(outputStream, res);
streamWrite(res, &result);
}
/////////////////////////////////////////////////////////////////////////
// Brook code block
/////////////////////////////////////////////////////////////////////////
{
float inputStream1<Length>;
float outputStream1<Length>;
float res1<1>;
streamRead(inputStream1, input);
hello_brook_check(inputStream1, outputStream1, (float)Length / 3.0f);
hello_brook_sum(outputStream1, res1);
streamWrite(res1, &result);
}
the programm will halt at "hello_brook_check(inputStream1, outputStream1, (float)Length / 3.0f);" and give error message " unhandled exception at .....".
but if I use it like:
/////////////////////////////////////////////////////////////////////////
// Brook code block
/////////////////////////////////////////////////////////////////////////
float inputStream1<Length>;
float outputStream1<Length>;
float res1<1>;
{
float inputStream<Length>;
float outputStream<Length>;
float res<1>;
streamRead(inputStream, input);
hello_brook_check(inputStream, outputStream, (float)Length / 3.0f);
hello_brook_sum(outputStream, res);
streamWrite(res, &result);
}
/////////////////////////////////////////////////////////////////////////
// Brook code block
/////////////////////////////////////////////////////////////////////////
{
streamRead(inputStream1, input);
hello_brook_check(inputStream1, outputStream1, (float)Length / 3.0f);
hello_brook_sum(outputStream1, res1);
streamWrite(res1, &result);
}
There will be no error, program will run correctly.
Is there anybody know what happen here?
