An apparatus and associated method of generating a multi-core communication topology. The topology corresponding to a predetermined number of cores of a multi-core computer, is generated with an application programming device. A number of nodes are described for mapping to the predetermined number of available cores of the multi-core communication topology. Properties of each of the number of nodes are specified. Communication between each of the nodes of the multi-core communication topology is specified using a dedicated multi-core communication library of an electronic memory of the application programming device. A validated output file is generated for the multi-core topology at the application programming device. The output file to is processed to generate a multi-core communication capable executable application program interface (API) for the multi-core computer.
