Automated empirical optimizations of software and the atlas project. edu Abstract. Finding and fixing data races is a difficult parallel programming problem, even for experienced programmers. Despite the usage of race detectors at application development time, programmers might not be able to detect all races. Severe damage can be caused after application deployment at clients due to crashes and corrupted data. Run-time race detectors can tackle this problem, but current approaches either slow down application execution by orders of magnitude or require complex hardware.

Each filter works in parallel within a pipeline stage on one frame of the video stream. Stage S1 (Gauss) performs a Gaussian blur by applying a convolution mask. Stage S2 (Gradient) applies a Sobel mask to compute the gradient strength and direction for each pixel. Stage S3 (Trace) traces the edges based on the gradients computed in the previous stage. Stage S4 (Suppress) suppresses pixels that are not on an edge. Stage S5 (Non-Max) performs some clean-ups in the picture by eliminating weaker edges that are parallel to stronger ones.
