DATA TRANSFER METHOD FOR PARALLEL COMPUTER AND PARALLEL COMPUTER PROCESSOR |
摘要 |
PROBLEM TO BE SOLVED: To improve the message transfer efficiency by sending a packet consisting of a packet body and a packet header including both transfer command and transmission control data to a reception processor to eliminate the need for copying the transfer data main body and also to transfer a single message with transfer of a single packet. SOLUTION: A packet header 11 provided on a main storage 4 of a transmitter PE 1 includes a command area 13 of a command 15 which instructs the transfer of data and a non-command area 14 which transfers the data designated by a program. The transmission control data 16 are set in the area 14. Then a transmission communication device 3 reads a packet body 17 pointed by the command 15 out of the storage 4 as a packet body 12. Then the device 3 adds the header 11 to the body 12 to form a packet 10 and sends this packet to an inter-PE connection network 2 to transfer it to the PE 1 of the reception side. |
