Title:
INTER-VIRTUAL CLUSTER COMMUNICATION PROCESSOR
Document Type and Number:
Japanese Patent JP2970082
Kind Code:
B2
Abstract:
PURPOSE: To obtain the inter-virtual cluster communication processor for reflecting surely an inter-cluster communication request on a virtual cluster.
CONSTITUTION: At the time of processing of a communication request to a virtual cluster executed by a virtual computer system of a real cluster 11, a maximum receiving frequency register 13 and an accumulation frequency register 14 are provided, a prescribed initial value is set to the accumulation frequency register 14, and a prescribed decision value corresponding to the number of pieces of real processors is always held in the maximum receiving frequency register 13. This processor is constituted so that in the case an interruption of a communication request to the virtual cluster is generated, the value held by the accumulation frequency register 14 is updated to a prescribed constant value, and only in the case the value held by the accumulation frequency register 14 before updating is an initial value, a simulation of a communication request notice to a communication request destination virtual cluster is executed, and in the case a result value becomes a prescribed relation against the decision value, the accumulation frequency register 14 is set to an initial value.
