Abstract
Stream computing has emerged as a new processing paradigm that processes incoming data streams in a real-time fashion. On the other hand, many recent efforts have shown the suitability of GPGPU to high performance computing. By bringing two new trends, this paper proposes new innovative method called GPU task parallelism to optimize stream computing with GPGPUs. In this paper we implement the proposed approach over SVD (Singular Value Decomposition) and IKA-SST, a powerful algorithm of change point detection. The experimental results show that the proposed implementation of SVD provides performance gain by around 4 times order against quad-core and the proposed implantation of IKA-SST provides around 20 times order against single-core. This result validates the scalability of our proposed approach.
