The project aims to find out the effect of preemption and context-switch on throughput and latency for a large number of isolated domains(processes). The operating system overhead will increase sharply with the increase in the number of domains, especially when the total number of active domains are more than the number of cores.

The server forks a large number of processes(based on the configuration parameter), and client will randomly generate the requests for these processes.

1. Clone the repository.

git clone https://github.com/ankit-iitb/os_project
cd os_project

2. Install Rust

curl https://sh.rustup.rs -sSf | sh
source $HOME/.cargo/env
rustup default nightly

3. Build the synthetic client-server application.

make

4. Run the synthetic application with a client and server. The client sends requests to the server, which transmits the payload of the same request in the response.

On the server:

cd linux/server/
./target/release/server

On the client:

cd linux/client/
./target/release/client

To update the configuration parameters, change linux/server/server.toml on the server side and linux/client/client.toml on the client side.

Change server_ip and num_process in server.toml and server_ip, num_tenants, and req_rate in client.toml.
