Title:
PARALLEL AND DISTRIBUTED COMPUTING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/251479
Kind Code:
A1
Abstract:
According to the present invention, in the environment that a plurality of computers are connected to each other through a plurality of data links, and perform communication and synchronization with each other by MBCF, the breaking of memory consistency due to disturbance of the order of packet arrival is eliminated. In the case where a plurality of computers 2 are connected to each other through a plurality of data links, and perform communication and synchronization with each other by MBCF, a transmission-side process has a transmission number-counting unit 201 that counts, for each reception-side process, the number of times transmission of an operation request packet has been made, and attaches the count of the operation request packet before or after counting up to the operation request packet. The reception-side process has a reception number-counting unit 202 that counts, for each transmission-side process, the number of times reception of the operation request packet has been made. When the count of the reception number-counting unit 202 is continuous to the count attached to the operation request packet, a transmission destination computer 2(2Y)2 processes the operation request packet, and updates the count of the reception number-counting unit 202 using the count attached to the operation request packet.
