There are two avenues for many-core machines to gain higher performance: increasing the number of processors, and increasing the number of vector units in one SIMD processor. A truly scalable algorithm should take advantage of both. However, most past research on scalable memory allocators scales well with the number of processors, but poorly with the number of vector units in one SIMD processor....
Expectation maximization (EM) algorithm is an iterative technique widely used in the fields of signal processing and data mining. We present a parallel implementation of EM for finding maximum likelihood estimates of parameters of Gaussian mixture models, designed for many-core architecture of Graphics Processing Units (GPU). The algorithm is implemented on NVIDIA's GPUs using CUDA, following the...
