Memory access control device, memory access control method and memory access control program

A memory access control method by a memory access control device,

• wherein said memory access control device comprises:
• a memory;
• a memory control unit configured to perform access control of said memory;
• and
• a software execution unit configured to execute software that manages said memory and said memory control unit,
• wherein said memory control unit comprises:
• a data transmission unit configured to perform multicast transfer that reads a data from said memory and transmits said read data to data transfer destinations through a network;
• a data reception unit configured to receive multicast transfer data from said network;
• and
• a reception data counter configured to indicate a number of multicast transfer data received by said data reception unit,
• wherein the memory access control method comprises:
• instructing, by said software execution unit, said memory control unit to perform a plurality of multicast transfers;
• and
• reading, by said software execution unit, respective reception data counters of said data transfer destinations for each checkpoint in sequence of said software to determine completion of said plurality of multicast transfers.

A memory access control program recorded on a computer-readable medium and executed by a memory access control device,

• wherein said memory access control device comprises:
• a data transmission unit configured to perform multicast transfer that reads a data from said memory and transmits said read data to data transfer destinations through a network;
• a data reception unit configured to receive multicast transfer data from said network;
• and
• a reception data counter configured to indicate a number of multicast transfer data received by said data reception unit,
• wherein the memory access control program performs a memory access control method comprising:
• instructing said memory control unit to perform a plurality of multicast transfers;
• and
• reading respective reception data counters of said data transfer destinations for each checkpoint in sequence of the memory access control program to determine completion of said plurality of multicast transfers.
