After implementing read from FIFO (i.e. after reading once from FIFO) the data in the FIFO is not flushed out of the FIFO. A read operation on FIFO is a move operation, can you please explain why is this happening?
Also, is there any size limit of a FIFO for single write operation? What is the maximum limit of the size of data that can be written to a FIFO by a single write operation?

I have completed this project for 50 clients.I also implemented shared memory and did practice on that.Now i am comfortable with various IPC mechnisms.

Hi,

I modify my project with adding Shared Memory for data flow. In my project data flow is as :

Requesting client -> Server = FIFO
Server -> Processing client = Shared Memory
Processing client -> Server = Pipe
Server -> Requesting client = Message Queues

Used Semaphore in Requesting client and Processing client….

But I am facing a issue, as I am running script of 60 clients it response to only 40 clients ,if I am running with 30 clients then it response to around 25 clients and so on….but that was not happening when I am not using shared memory in this project….

can anybody let me know ?

i have successfully implemented my ipc project with 5 requesting clients & 5 processing clients and 1 server.first i sent the data from requesting clients by using fifo with semaphore & then sent this data from server to processing client by using message queue & using forf() ,excl() also……& again sent the result to the server by using pipe(),……..and sent the result to the different requesting clients by using pipe()…….

Status: My project is working for four reqclients and 4 processing clints.

Description:
In this project i’m used fifo for transfer the data from clients to server and used message queue to transfer data to process clients from server.
To transfer the data in proper way we use syncronization technique semaphore.After calculation result in process result is transfer to server using single pipe.
Semaphore is again used in the processes,to transfer result in proper manner to server .Result is transfer in req. clients from server with msgqueue.

i have implemented ipc project till 3 client and 3 process , using fifo and semaphore i send data to server and after that data is send to the process client using message qeue.
processed data is send to the server using pipe and semaphore.processed data is on server
till now ,i will use shared memory to send the data to clients.
