A method for sending data, from an upstream device to a downstream device, including sending a piece of data from one among a plurality of virtual channels sharing the same input buffer memory of the downstream device, if this virtual channel uses a number of memory locations of the input buffer memory strictly less than a current ceiling. It further comprises measuring a communication latency between the upstream and downstream devices, and calculating the current ceiling from the measured latency.

A computer device with synchronization barrier including a memory and a processing unit capable of multiprocess processing on various processors and enabling the parallel execution of blocks by processes, the blocks being associated by groups in successive work steps. The device further includes a hardware circuit with a usable address space to the memory, capable of receiving a call from each process indicating the end of execution of a current block, each call comprising data. The hardware circuit is arranged to authorize the execution of blocks of a later work step when all the blocks of the current work step have been executed. The accessibility to the address space is achieved by segments drawn from the data of each call.
