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.
