The present invention provides a heterogeneous cloud operating system capable of uniformly dispatching and managing heterogeneous computing resources.The system comprises: OpenPOWER architecture computing nodes, wherein OpenStack computing components and OpenStack networking components are installed; X86 architecture computing nodes, wherein OpenStack computing components and OpenStack networking components are installed; and X86 architecture control and management nodes, wherein OpenStack control management components are installed and comprise computing management components. The OpenPOWER architecture computing nodes and the X86 architecture computing nodes are connected to each other over the network, and are respectively connected to the X86 control and management nodes through a network. The OpenPOWER architecture compute nodes are divided into the OpenPOWER available domain. The X86 architecture computing nodes are divided into the X86 available domain. After the X86 architecture control and management nodes receive the scheduling request for computing resources, the computing management components running on the X86 architecture control and management nodes send the scheduling request to computing nodes in the available domains selected by the scheduling request, and performs computational operations on the selected computing nodes.
