Patent ID: 7483817

Claim:
A test method of a data processing system in which a plurality of processors are mutually connected by one or a plurality of connection mechanisms, the test method comprising: a connection characteristics determination step in which whether the connection mechanisms are different in connection characteristics in terms of hardware implementation is determined; and a first load test execution step in which, if the connection characteristics of the connection mechanisms have no difference therebetween, a load test combination program in which a first test program and a first load program having a first load effect are combined is determined for all the processors, so as to execute a long-time load test, the first load test execution step including: a first load test combination determination step in which execution time of a no-load state in which merely the first test program is executed by all the processors is compared with execution time of a loaded state of the first test program when the first test program is executed by one of the processors and the first load program is executed concurrently by all remaining processors, where, if the execution time of the loaded state is longer than the execution time of the no-load state, the first load program is determined to have a first load effect, and a first load test combination program is determined in which the first test program and the first load program are combined; a first tuning step in which, with respect to the first load test combination program, one of the processors is caused to execute the first test program, the remaining processors are caused to execute the first load program while changing the number of the processors, to obtain a minimum number of the processors at which the execution time of the first test program is saturated and not changed even when the number of the processors executing the first load program is increased, and the minimum number of the processors and a determination result are added to the first load test combination program to provide a first tuned load test combination program; and a load test allocation step in which, in accordance with the first tuned load test combination program, the first test program and the first load program having a high load effect are prioritized in allocation to the processors.
