[Final] Add SimGrid and scripts

README.md

@@ -8,4 +8,26 @@ Implementation of Prefix Sum and Tree-based Reduce using mpi4py.
 - OpenMPI (System installed)
 
 ## Usage
-Run via `run_tests.sh`.
+
+### 1. Parallel Prefix Sum (Problem 1)
+```bash
+mpiexec -n <NP> python3 src/problem1/prefix_sum.py
+```
+
+### 2. Manual Tree Reduce & Benchmark (Problem 2)
+```bash
+mpiexec -n <NP> python3 src/problem2/benchmark.py
+```
+
+### 3. SimGrid Simulation
+SimGrid configurations are provided in `simgrid/`. 
+To run with SimGrid (if SMPI/Python bindings are configured):
+```bash
+smpirun -platform simgrid/platform.xml -hostfile ... python3 src/problem2/benchmark.py
+```
+
+## Running Tests
+Execute the helper script:
+```bash
+bash run_tests.sh
+```

run_tests.sh

+#!/bin/bash
+set -e
+
+echo "Running Problem 1: Prefix Sum (NP=3)"
+mpiexec -n 3 python3 src/problem1/prefix_sum.py
+
+echo "-----------------------------------"
+echo "Running Problem 2: Manual Reduce Benchmark (NP=3)"
+mpiexec -n 3 python3 src/problem2/benchmark.py
