Distributed computing system

A distributed computing system including a plurality of computers on which a plurality of programs run, wherein each of said computers comprises:

• means for defining urgency levels, said urgency levels being common in all of said plurality of computers;
• means for allocating one of said urgency levels to each of said plurality of programs;
• means for allocating each of said plurality of programs to a respective one of said computers for execution thereof;
• priority levels conversion means for performing a conversion between said allocated urgency level of processing by a program and a priority level of processing by the program in accordance with performance and load of said computer,
• wherein the urgency level of processing execution of the program is determined with respect to all of said plurality of programs run on all of said plurality of computers and indicates how fast the program should be executed;
• and
• priority level changing means for changing a priority level of processing of the program, which executes the processing, in accordance with the priority level indicated by said priority level conversion means,
• wherein each of said plurality of programs specifies an urgency level of processing by a program when said program requests another program to perform the processing.
