  • Publication number: 20250094371
    Abstract: A local terminal transmits to a processing device an RDMA transmission packet in which processing data to be transferred to a memory of an accelerator of each of a first remote terminal and a second remote terminal is set. The processing device acquires a QPN from the first remote terminal, converts a Destination QP of a BTH of the RDMA transmission packet into the QPN acquired from the first remote terminal, and transmits a converted RDMA transmission packet to the first remote terminal. When a connection is established, the processing device acquires a QPN from the second remote terminal, converts the Destination QP of the BTH of the RDMA transmission packet into the QPN acquired from the second remote terminal, and transmits a converted RDMA transmission packet to the second remote terminal. Each of the first and second remote terminal transfers the processing data to the memory of the accelerator.

  • Publication number: 20070132549
    Abstract: A manufacturer of an article generates a keyword, and electromagnetically writes the keyword into an RFID and prints the keyword on a guarantee card. The RFID tag is then affixed to the article, and the article is packed along with the guarantee card and shipped. When making a sale, a retail store hands over the guarantee card to a customer who buys the article. When the customer wishes to sell the article, a purchasing store reads the keyword written to the RFID tag affixed to the article and asks the customer to furnish the keyword. If the keyword furnished by the customer, by referring to the guarantee card, etc., is identical to the keyword read from the RFID tag, the customer is deemed a genuine owner of the article.
