<p><P>PROBLEM TO BE SOLVED: To enhance the use efficiency of a memory space in receiving RDMA (Remote Direct Memory Access) transfer. <P>SOLUTION: A virtual identifier transmission means 1c transmits a virtual identifier corresponding to a process 1b to a communication party. Then, when the process 2b of a node 2 issues a transfer request specifying the virtual identifier, a memory region securing means 2e transmits a request for securing a data-receiving memory region to a node 1 when no memory region is secured. In the node 1, a memory region securing means 1d secures the data-receiving memory region of a communication apparatus 1a on the memory space. In the node 2, a data transmission control means 2h outputs a data transfer instruction to a communication apparatus 2a. Finally, the communication apparatus 2a outputs transfer data 3 in the memory region managed by the process 2b with RDMA transfer specifying the data-receiving memory region. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
