Description: 1. Buffer pool of N buffers as a critical resource: When the producer task reads data from the data source file, it will apply for a buffer and put the data in the buffer. The consumer task takes data from a buffer and prints out the contents. When a producer task is accessing the buffer, other producer and consumer tasks cannot access it. When a consumer task is accessing the buffer, other producer and consumer tasks cannot access the buffer. Mutex is used to access the buffer pool.

Description: a program is designed to create three sub processes from one process, three sub processes is the producer process, and the two is the consumer process. 2) the father child process communicates with the shared storage area created by the parent process, and sends ten values in one array to the shared memory composed of 5 buffers by the producer process. L 3) the two consumer processes take turns to receive and output the ten values, and add values to each of the two consumer processes. 4) take into account the production speed of the producer process and the speed of the consumer process.)

Description: Write three different programs: CMD1. C, cmd2. C and cmd3. C. the function of each program is self-defined, which is compiled into executable files: CMD1, cmd2, and cmd3. Then write a program to simulate the function of shell program: according to the string input by the user (representing the corresponding command name), create a child process for the corresponding command and let it execute the corresponding program, while the parent process waits The child process ends before receiving the next command. If the received command is exit, the parent process ends and exits the simulated shell; if the received command is invalid, "command not found" is displayed and continues to wait for the input of the next command.

Description: (1) First come first served (FCFS) and shortest work first (SJF); First come, first served (FCFS) algorithm: the job / process is scheduled according to the order of entering the system, and the first in the system is scheduled first; that is to start the job / process with the longest waiting time. Short job first (SJF) scheduling algorithm: select one or several jobs with the shortest estimated running time from the backup queue and put them into memory to run. (2) Non preemptive and preemptive priority scheduling algorithms Non preemptive priority scheduling algorithm: once the processor is assigned to the process with the highest priority in the ready queue, the process will continue to execute until it is completed; or when the process abandons the processor due to some event, the system can reassign the processor to another process with the highest priority.
