The utility model relates to computer technology and can be used in the creation of computer systems. The utility model improves the functionality and performance of the device in case of failure of information processing units by reducing delays in system reconfiguration time. The device includes a block of buffer memory of unexecuted commands, as a result of which in case of failure of the computing unit during the execution of the command, that is, exceeding the waiting time for the execution of this command, the unexecuted command is written to the block of buffer memory of unexecuted commands and, regardless of the general queue available in the environment of command formation, is first transferred for execution to an efficient computing unit
