Abstract
A system including at least one computation node including a memory, a processor reading/writing data in a work area of the memory and a DMA controller including a receiver receiving data from outside and writing it in a sharing area of the memory or a transmitter reading data in said sharing area and transmitting it outside. A write and read request mechanism is provided in order to cause, upon request of the processor, a data transfer, by the DMA controller, between the sharing area and the work area. The DMA controller includes an additional transmitting/receiving device designed for exchanging data between outside and the work area, without passing through the sharing area.
