Requirment - Run with Signal Switch

In this experiment, 2 physical workers, 1 physical PS (Parameter Server) and 1 switch is used.

Getting Started

$ git clone https://github.com/ATP-NSDI/ATP.git

Run Tofino Switch

Compile P4 Program and Start the Tofino Model (Terminal1)

If you are using physical switch, compile the switch program then jump to Terminal 2 directly.

$ cd $SDE

$ $TOOLS/p4_build.sh ~/git/p4ml/p4src/p4ml.p4

# (Optional) for software Tofino behavior model
$ ./run_tofino_model.sh -p p4ml

Load Specified Switch Program (Terminal2)

$ cd $SDE

$ ./run_switchd.sh -p p4ml

Enable Ports and Install Entries (Terminal3)

$ $SDE/run_p4_tests.sh -t $ATP_REPO/ptf/ -p p4ml 

$ $TOOLS/run_pd_rpc.py -p p4ml $ATP_REPO/run_pd_rpc/setup.py 

Run Parameter Server

Compile and Run Server (Terminal4)

$ cd $ATP_REPO/server/

$ make

# Usage: ./app [AppID]
sudo ./app 1

wait until all threads finish their QP creation.

Compile and Run Workers

$ cd $ATP_REPO/client/

$ make

Run Worker1 (Terminal5)

# Usage: ./app [MyID] [Num of Worker] [AppID] [Num of PS]
$ sudo ./app 0 2 1 1

Run Worker2 (Terminal6)

# Usage: ./app [MyID] [Num of Worker] [AppID] [Num of PS]
$ sudo ./app 1 2 1 1

Then you can switch to Terminal 5/6 to the see bandwidth report.
