| + | ====== Stream Cluster ====== | ||
| + | Our streamcluster kernel is modified upon the streamcluster benchmark in the Parsec suite developed by Princeton University. | ||
| + | The following is the decription of the streamcluster from Parsec technical report[1] | ||
| + | |||
| + | "For a stream of input points, it finds a predetermined number of medians so that each point is assigned to its nearest center. The quality of the clustering is measured by the sum of squared distances (SSQ) metric." | ||
| + | |||
| + | Our CUDA version parallelized the pgain function. "Given a preliminary solution, the function computes how much cost can be saved by opening a new center. For every new point, it weighs the cost of making it a new center and reassigning some of the existing points to it against the savings caused by minimizing the distance between two points x and y for all points." | ||
