Abstract: A container communication method for parallel-applications and a system using the method are disclosed. The method includes: when a first process of a first container has to communicate with a second process of a second container and the first and second containers are in the same host machine, creating a second channel that is different from a TCP (Transmission Control Protocol)-based first channel; the first container sending communication data to a shared memory area assigned to the first container and/or the second container by the host machine and send metadata of the communication data to the second container through the first channel; and when the second process acknowledges receiving the communication data based on the received metadata, transmitting the communication data to the second container through the second channel and feeding acknowledgement of the data back to the first process through the first channel.
