Distributed memory type parallel computer and write data transfer end confirming method thereof

摘要

A distributed memory type parallel computer and a write data transfer end confirming method of the distributed memory type parallel computer, in which a series of processes to confirm a write data transfer end between plural computing nodes can be made in high speed, are provided. A computing node in the distributed memory type parallel computer provides a request accepting section, a data accepting section, an arbitration section, an address transforming section, a request/data outputting section, an EOT (end of transfer) judging section, and a selector. By using the EOT judging section and the selector in a remote node, a transfer end mark can be added to transfer data themselves. Therefore, without executing processes before and after write data transfer by a CPU in a local node, an end confirmation of a write data transfer from the remote node to the local node can be realized by adding a transfer end mark to the transfer data. With this, a series of the processes to confirm the write data transfer end can be executed in high speed.
