APPARATUS AND METHOD FOR DATA STREAM PROCESSING USING MASSIVELY PARALLEL PROCESSORS

摘要

The present invention relates to a data stream processing apparatus and a method that use Graphics Processing Units (GPUs) to speed up data stream processing. For that, said apparatus comprises three modules where a logic execution query plan is first built and implemented by using a Generic Purpose GPU (GPGPU) application programming interface language in a way such that the resulting query plan code has very few program control. instructions and function calls allowing much more unrestricted parallelization by the GPU. Finally, the communication between the CPU and the GPU and back is improved- resulting in a better performance and efficiency of processing and managing data. The apparatus and method of the present invention are useful in applications that require high performance and throughput in data analysis, such as monitoring applications in financial systems, telecommunications, energy and utilities distribution or consumption, manufacturing, traffic analysis and control, computer network and security management, real-time data warehousing, or click stream analysis.
