1. A load testing apparatus which conducts a load test of a parallel processor system, said parallel processor system havinga plurality of arithmetic units each having a packet transmission and receiving function;

  • and a network for interconnecting said plurality of arithmetic units;

    said load testing apparatus comprising;

    a measuring unit which measures the transmission time between a pair of said arithmetic units as an expected value based on the result of combining, without overage or shortage, said plurality of arithmetic units, wherein said pair of said arithmetic units is a combination of an arithmetic unit at the source (source arithmetic unit) and an arithmetic unit at the destination (destination arithmetic unit);

    a load test conducting unit which conducts a load test by transmitting a plurality of packets from said plurality of source arithmetic units to the corresponding destination arithmetic units, respectively, based on the result of combining, without overage or shortage, said plurality of arithmetic units into said pairs of arithmetic units, on condition that no packet is transmitted from a plurality of source arithmetic units to a single destination arithmetic unit, and measuring the transmission time between each of said pairs of arithmetic units; and

    an evaluation unit which evaluates the performance based on the result of comparing the transmission time for each pair measured by said load test conducting unit with the expected value obtained by said measuring unit for each said pairs of arithmetic units.
