Information processing apparatus, control method, and control program

摘要

At least one node(20) of a plurality of nodes in an information processing apparatus(1) executes the following processing for data included in a memory of one node or other nodes and stored in a shared memory area which the node and the other nodes access. That is, the node detects an ICE which occurs over a predetermined number of times within a predetermined time or a PCE which occurs at a single location in the shared memory area. When the error is detected, the node performs control to prevent the node and the other nodes from accessing the shared memory. The node recovers the data in a memory area different from the shared memory area. The node notifies information about the different memory area to the other nodes. The node performs control to resume the access to the data from the node and the other nodes.
