Proposal of Shared Memory Access Methods for Lambda Computing Environment

Optical transmission technology is studied actively in order to realize high-speed transmission and broadband networks. However, conventional packet-based switching technology cannot realize the true high quality communication for each connection. Then we propose λ computing environment which has the virtual channels utilizing optical fibers connecting computing nodes. So we can offer the high-speed and reliable connection path/pipe which is necessary for SAN and Grid computing, to the users with such virtual channels. In this paper, we propose and evaluate an access methods to the virtual ring network which consists of such channels when we use the ring network as a shared memory. As a result, we can show the performance of the proposed method to access the shared memory on photonic networks.
