Abstract: Provided is a many-core system including a resource unit including a resource needed for execution of an operating system and a resource needed for execution of a lightweight kernel, a programing constructing unit configured to convert an input program into an application program and to load the application program into the resource unit, a run-time management unit configured to manage a running environment for executing the application program, and a self-organization management unit configured to monitor the application program and the resources in the resource unit, to dynamically adjust the running environment to prevent a risk factor from occurring during the execution of the application program, and to cure a risk factor which occurred.

Abstract: Disclosed is an apparatus and method of processing input and output in a multi-kernel system. A method of processing input and output in a multi-kernel system according to the present disclosure includes: setting a shared memory between a first kernel on a main processor and a lightweight kernel on a parallel processor; setting a data transmission and reception channel between the first kernel on the main processor and the lightweight kernel on the parallel processor using the shared memory; providing, on the basis of the data transmission and reception channel, an input/output task that occurs in the lightweight kernel to the first kernel on the main processor; processing, by the first kernel on the main processor, an operation corresponding to the input/output task; and providing a result of the processing to the lightweight kernel.

Abstract: Provided is a method of scheduling threads in a many-cores system. The method includes generating a thread map where a connection relationship between a plurality of threads is represented by a frequency of inter-process communication (IPC) between threads, generating a core map where a connection relationship between a plurality of cores is represented by a hop between cores, and respectively allocating the plurality of threads to the plurality of cores defined by the core map, based on a thread allocation policy defining a mapping rule between the thread map and the core map.
