10, the input of the memory unit of the state glass and the input of the first switch, and the outputs of the buffer memory blocks are the outputs of the device 2. The device’s disadvantage is

15 that it has a negligible functionality, since the selection of the channel does not take into account the probability of its failure. The purpose of the invention is the expansion

20 functional capabilities by providing a rapid response of the device to a change in the state of the system.

The goal is achieved

25 in that the device contains a block

storing the state of the processes, the block storing the data on the loading of the processors, the numerical block and the second commutator, the outputs of the buffer memory blocks are connected to the first input

In the drawing, a structural diagram of the device is presented.

A device for inserting a quota into the computing system, contains an input shaper 1, a block 2 deciphering parameters of the quotation, a shaper 3 processor numbers, a pey switch 4, a buffer memory blocks 5, a shaper b of a communication channel number, a second switch 7, a storing block 8 state of processors, block 9 of data processing on loading processors, block 10 of storage of state of communication channels, arithmetic block 11, block 12 of memory of system state.

The device works as follows.

The input of the imager 1 is received from users of the system. Each application contains a passport, which indicates such parameters as the duration of the application's tasks, the required number and volume of the VOB source data, assuming the type of channel through which the application can be transmitted, the acceptable processor type, application priority etc. Block 2 decrypts the passport application and transmits the received data to the driver 3. In the driver 3, in accordance with the passport of the application, the number of the processor is selected, and in the driver 6, the channel through which the application is transmitted is selected.

When selecting a channel, the data obtained from blocks 8, 9, 10 and 11 are also taken into account.

The above blocks work as follows.

From the Output of blocks 5 to the input of switch 7, information is received about the nature of the functioning of the system: the number of tasks solved by the processor, the operability of the processor as a whole and each section, the state of each channel (idle, busy or faulty), In blocks 8, 9 and Y,

at clock points in time, data is selected according to the health or malfunction of each processor entering the system, and all its sections, the number of tasks currently being performed by each processor, and the channel status. The resulting data is stored in block 12 and used by the li block. In block 11, the data on a priori probabilities of a processor's communication failure, on the dependences of the probabilities of the failure-free operation of these devices on time, etc. are entered. Using the specified data, as well as the duration of the solution of the application, block 11 for each application that enters the system calculates the probability of servicing the application without equipment for each channel from the set of allowed channels selected by blocks 3 and 6. The calculated probabilities are memorized in block 12. In addition, block II at each clock point in time is based on data obtained from blocks 8, 9, and 10 | recalculates a priori probabilities of failing channels and processors. Thus, a statistical analysis of the system operation takes place. Blocks 3 and b, based on the data received from block 2, blocks 8, 9 and 10 and block 11, select a communication channel that meets the requirements of the application passport with the maximum likelihood of servicing the application without equipment failure. The signal from the output of block 6 arrives at k-jMMyTaTOp 4 and into switch 7, promptly before the onset of the clock point in time signals about channel occupancy. Switch 4 on, shows the selected channel. The application enters block 5 and further for execution. The system processes the next one.

Thus, the invention allows to expand the functional capabilities of the system, increase the reliability of the system as a whole, as well as credit. This makes it possible to quickly identify less reliable elements and take measures to improve the reliability of their operation.
