Method and system for installing program in parallel computer system

A parallel computer system including plural nodes, comprising:

• a storage device for storing a program which is executed in parallel in said plural nodes of said parallel computer system;
• a distributing node being one of said plural nodes, and for delivering said program to remaining nodes of said plural nodes;
• and
• receiving nodes for receiving said program delivered from said distributing node,
• wherein said distributing node includes a master install control unit, said master install control unit notifying said receiving nodes, which receive said program, of delivery of said program before delivering said program, reading said program to be delivered from said storage device, and delivering said program simultaneously to said receiving nodes;
• and
• said receiving node includes an install control unit, said install control unit receiving said program from said distributing node, and storing said program in a storage device of said receiving node itself.

A medium storing a computer executable installing program for a parallel computer system, said computer executable installing program comprising:

• a step of causing a distributing node to initiate an install control program in plural receiving nodes which receive a program;
• a step of causing said distributing node to read a program to be delivered in order to be executed in each node, from a storage device of said distributing node itself, and to store the read program in a first buffer;
• a step of causing said distributing node to read said program from said first buffer, and to send the read program to said receiving nodes;
• a step of causing said receiving node to store a received program in a second buffer;
• a step of causing said receiving node to read a distributed program from said second buffer, and to store the read program in a storage device of said receiving node itself;
• and
• a step of causing said distributing node to notify all said receiving nodes of completion of program delivery after completing delivery of said program.
