Job scheduling research for parallel systems has been widely exploited in recent years, especially in centers with high performance computing facilities. In the recent past we presented the eNANOS execution environment which is based on a coordinated architecture, from the CPU allocation to the grid scheduling, providing a good low level support to perform an efficient high level scheduling. In this...
The color correlogram has proven its worth as an image descriptor for both comparison and retrieval. The paper presents a case study of developing efficient color correlogram algorithms on the STI Cell Broadband Engine (Cell B. E.), which is a state-of-the-art heterogeneous multicore architecture that consists of a traditional microprocessor (PPE) with eight SIMD co-processing unit (SPE) integrated...
Heterogeneous computing is a new branch of parallel processing and is expected to reach super-speedup. It is an important step for heterogeneous computing to extract the heterogeneity hiding in a program. Such work is rather difficult, and some concepts and terminology are ambiguous. From the point of view of program structure, this paper presents formal definitions of SISD, SIMD and MIMD, which are...
