Abstract: A multi-node system for making the data transfer between nodes via each internodal crossbar switch comprises a plurality of internodal crossbar switches having a switch for transmitting the transfer data from a plurality of nodes to the node of transfer destination. If a fault occurs in the switch, the system is configured to make the data transfer between the nodes via any other internodal crossbar switch than the internodal crossbar switch having the switch where the fault occurs.

Abstract: A plurality of inter-nodal control means are provided at a connection part between an inter-nodal crossbar switch for an inter-nodal data transfer and each node so as to process one inter-nodal transfer command, and an inter-nodal transfer capacity can be variably set in accordance with a capacity within a node. In this case, in the data transfer apparatus, at a connection part between an inter-nodal crossbar switch 11 for the inter-nodal data transfer and each node 12, 13, a plurality of inter-nodal control devices (RCUs) 123, 124; 133, 134 for processing one inter-nodal transfer command are provided.

Abstract: The holder means 2 holds active library information 2-1 to 2-m, determining the retrieval sequence of active library storage areas to be retrieved, every program types C1 to Cm. The selector means 5 selects the active library information 2-1 corresponding to the type C1 of the program 4-1 in execution. The dynamic linker 3 retrieves the library X1 with an identifier x specified from program 4-1 in execution, in accordance with the retrieval sequence of the active library storage areas 1-1 and 1-2 indicated by the selected active library information 2-1, and then links it to the program 4-1. When the program 4-2 of the program type C2 issues a link request specifying the same identifier x, the active library information 2-2 is selected and the active library storage area 1-2 is first retrieved. Thus, the library X2 with the identifier x is linked to the program 2-2.
