摘要

The objective of the present invention is to set an optimal multiplicity even under conditions in which operating environment factors affecting an optimal value of a multiplicity limit change. The present invention is provided with: a performance counter (211) which measures operating conditions of hardware in an object computer; an operational conditions acquisition unit (221) for acquiring operational conditions measured by the performance counter (211) whenever an acquisition operation for the operational conditions is started; a multiplicity limit calculation unit (222) which calculates a multiplicity limit which is an upper bound for the number of processes in which processing is to proceed simultaneously in parallel using the operational conditions acquired by the operational conditions acquisition unit (221); and a control unit for the number of simultaneous connections (223) which controls the number of simultaneous connections to the object computers with the multiplicity limit calculated by the multiplicity limit calculation unit (222) as an upper limit.
