Abstract: PURPOSE: A data communication method between processors, a computer-readable recording medium including a code, and a multi processor computing system thereof are provided to eliminate the need to use another physical communication buffer by using an unused area as a buffer. CONSTITUTION: A parallel processing object allocating a 2D data area to each processor and allocating a data area exceeding 2D to a processor array is generated(S110). A communication object defining a data communication method between processors is generated by using the parallel processing object(S120). A value of a boundary area of a second sub-data area allocated to a second processor of the processor array is transmitted to a first processor of the processor array according to data communication methods defined by the communication object(S130). [Reference numerals] (S110) Generating a parallel processing object for dividing a 2D data area of 2D or more data areas into a plurality of sub-data areas, allocating in each processor, and allocating data area of dimensions exceeds 2D in a processor array; (S120) Generating a communication object defining a data communication method between processors using the parallel processing object; (S130) Transmitting the value of a boundary area of a second sub-data area allocated to a second processor of the processor array to a first processor of the processor array according to the data communication method defined by the communication object; (S140) Calculating the boundary area of a first sub-data area allocated in the first processor using the transmitted value; (S150) Outputting a value of a data area of 2D or more by one processor after one processor of the processor array receives a value of a sub-data area allocated to other processors from other processors after terminating the calculation of the sub-data area allocated to each processor;
