Node-to-node data transfer control device, node-to-node data transfer control method, and program

摘要

PROBLEM TO BE SOLVED: To efficiently allocate an area to a distributed shared memory shared between nodes, and to release the allocation while maintaining efficiency in performing allocation.;SOLUTION: A node address association means 1-B has a means converting a memory address into a node address and a table wherein the memory address and the node address are associated, or has a means corresponding to calculation associating the memory address and the node address. The memory address is converted into the node address based on a prescribed rule such as retrieval of the table, partial masking or a shift of the memory address, or the calculation. When the node address association means 1-B releases the allocation of a part or all of the memory area allocated for the distributed shared memory 1-C on a local memory as the distributed shared memory 1-C, the node address association means 1-B precedingly releases the allocation of the area present in an address different form initial allocation inside the area of the distributed shared memory 1-C to improve use efficiency of a local memory area.;COPYRIGHT: (C)2009,JPO&INPIT
