Abstract
In InfiniBand, communication is made between a first queue-pair (QP) allocated to a first user-program executed within a first apparatus and a second QP allocated to a second user-program executed within a second apparatus. The first apparatus sets a specific code to a send work-request, after moving information previously set to the send work-request to a portion of the data, and transmits the data added with a first QP number identifying the first QP to the second apparatus. The second apparatus determines that the received data is added with the QP number, when the specific code is set to a receive work-request, identifies the first user-program based on the QP number, and sends the data to the second user-program via the receive work-request after deleting the QP number from the data and moving information stored in the portion of the data to the receive work-request.
