Hi Dave,
Again on the KMeans sample. I am little unclear why the following two
updates in lines 85 and 87 are not done atomically. These updates are done
by async activities for each point.
for (var d:Int=0 ; d<DIM ; ++d) {
local_new_clusters()(closest*DIM+d) +=
points(Point.make(p,d));
}
local_cluster_counts()(closest)++;
Thank you,
Saliya
