We present an alternative algorithm of fully decentralized resource discovery in Grid computing, which enables the sharing, selection, and aggregation of a wide variety of geographically distributed computational resources. Our algorithm is based on a simply unicast request transmission that can be easily implemented. The addition of a reservation algorithm(More)
We have proposed the effective stencil computation method and the architecture by employing multiple small FPGAs with 2D-mech topology. In this paper, we show that our proposed architecture works correctly on the real 2D-mesh connected FPGA array. We developed a software simulator in C++, which emulates our proposed architecture, and implemented two(More)
GPUs for numerical computations are becoming an attractive alternative in research. In this paper, we propose a new parallel processing environment for matrix multiplications by using both CPUs and GPUs. The execution time of matrix multiplications can be decreased to 40.1% by our method, compared with using the fastest of either CPU only case or GPU only(More)
This paper evaluates the effect of an auto-tuning facility with the user's knowledge for numerical software. We proposed a new software architecture framework, named FIBER, to generalize auto-tuning facilities and obtain highly accurate estimated parameters. The FIBER framework also provides a loop-unrolling function and an algorithm selection function to(More)
Many-core processors which have thousands of cores on a chip will be realized. We developed an infrastructure which accelerates the research and development of such many-core processors. This paper describes three main elements provided by our infrastructure. The first element is the definition of simple many-core processor architecture called M-Core. The(More)
We have developed a function-level processor simulator, SimCore/Alpha Functional Simulator Version 2.0 (SimCore Version 2.0), for processor architecture research and processor education. This paper describes the design and implementation of SimCore Version 2.0. The main features of SimCore Version 2.0 are as follows: (1) It offers many functions as a(More)
