The specification of hardware is
GPU used : NVIDIA GTX280 (has about 30 multiprocessors each with 8 processors, frequency is 1.29 GHz)
CPU used : Intel i5D, 4 cores, frequency of 2.67 GHz.
GPU memory, bandwidth : 1 GB, 141.7GB/s
To get a more clear picture speedup calculated only after the I/O file is completed. Results that are obtained from the proposed differential (data size dependent) approach are compared with other approaches like HP_k_means (for smaller hence low-dimension data), UV_k-means , GMiner (for large data sets) and then fialy the performance is compared with CPU.
A. Small data sets (Low –dimension)
For this a data set of sizes 2 million and 4 million with varying values of “k” (number of the distinct sets/groups) and “d”…
