 【CPU-GPU-kmeans】
-Two parallel and optimized implementations of the k-means clustering algorithm:
-1. k-means on CPU: thread parallelization using OpenMP, auto-vectorization using AVX units
-2. k-means on GPU: using shared memory, dynamic parallelism, and multiple streams
+Optimized parallel implementations of the k-means clustering algorithm:
+1. on multi-core CPU with vector units: thread parallelization using OpenMP, auto-vectorization using AVX units
+2. on NVIDIA GPU: using shared memory, dynamic parallelism, and multiple streams
 In particular, for both implementations we use a two-step summation method with package processing to handle the effect of rounding errors that may occur during the phase of updating cluster centroids.
