+# K8s Power Manager
+
+## Components
+1. **PowerManager Controller**: ensures the actual state matches the desired state of the cluster.
+2. **PowerConfig Controller**: sees the powerConfig created by user and deploys Power Node Agents onto each node specified using a DaemonSet.
+    - powerNodeSelector: A key/value map used to define a list of node labels that a node must satisfy for the operator's node
+      agent to be deployed.
+    - powerProfiles: The list of PowerProfiles that the user wants available on the nodes
+3. **Power Node Agent**: containerized applications used to communicate with the node's Kubelet PodResources endpoint to discover the exact CPUs that
+   are allocated per container and tune frequency of the cores as requested
+
+
+## Setup
+### 1. Manual
+#### on both nodes
+    git clone -b new_test --depth=1 https://github.com/vhive-serverless/vhive.git
+    cd vhive
+    mkdir -p /tmp/vhive-logs
+    ./scripts/cloudlab/setup_node.sh stock-only > >(tee -a /tmp/vhive-logs/setup_node.stdout) 2> >(tee -a /tmp/vhive-logs/setup_node.stderr >&2)
+
+#### for worker
+    ./scripts/cluster/setup_worker_kubelet.sh stock-only > >(tee -a /tmp/vhive-logs/setup_worker_kubelet.stdout) 2> >(tee -a /tmp/vhive-logs/setup_worker_kubelet.stderr >&2)
+    sudo screen -dmS containerd bash -c "containerd > >(tee -a /tmp/vhive-logs/containerd.stdout) 2> >(tee -a /tmp/vhive-logs/containerd.stderr >&2)"
+
+#### for master
+    sudo screen -dmS containerd bash -c "containerd > >(tee -a /tmp/vhive-logs/containerd.stdout) 2> >(tee -a /tmp/vhive-logs/containerd.stderr >&2)"
+    ./scripts/cluster/create_multinode_cluster.sh stock-only > >(tee -a /tmp/vhive-logs/create_multinode_cluster.stdout) 2> >(tee -a /tmp/vhive-logs/create_multinode_cluster.stderr >&2)
+
+ join the cluster from worker, answer 'y' to master
+
+## Setup 
+### 1. Manual
+
+Execute the following below **as a non-root user with sudo rights** using **bash**:
+1. Run the node setup script:
+    ```bash
+    ./examples/powermanger/setup_power_manager.sh;
+
+   go run ./examples/powermanger/experiment_1.go
+
+   while true; do current_time=$(date -u +%s%3N); cpu_average=$(grep 'MHz' /proc/cpuinfo | awk '{ total += $4 } END { print total / NR }'); echo "${current_time}: ${cpu_average}" >> memory.txt; sleep 0.01; done
+
+   while true; do
+    current_time=$(date -u +%s%3N)
+    sudo perf stat -e instructions,cycles -I 1000 -o perf_output.data sleep 1
+    ipc=$(grep -E '(instructions|cycles)' perf_output.data | awk '{ total += $1 } END { if (total) print total / 2 }')
+    echo "${current_time}: ${ipc}" >> ipc_results1.txt; done
+
+   while true; do current_time=$(date -u +%s%3N); stats=$(sudo turbostat --Summary --quiet --show Busy%,Avg_MHz,PkgWatt); echo "${current_time}, $stats" >> $output_file; sleep 0.01; done
+
+2. Clean Up
+   ```bash
+   ./scripts/github_runner/clean_cri_runner.sh
+   ```
