+# Massiv vs Accelerate Benchmark Suite
+
+This project benchmarks and compares the performance of [Massiv](https://github.com/lehins/massiv) and [Accelerate](https://github.com/AccelerateHS/accelerate) Haskell array libraries using a variety of operations (map, dot product, stencil/mean blur).
+
+## Project Structure
+
+- `app/Main.hs` — Main benchmarking entry point (Criterion-based)
+- `src/` — Library and dependency sources (submodules)
+- `Dockerfile` — Containerized build and run environment matching target LLVM pipelines
+- `cabal.project`, `massiv-vs-accelerate.cabal` — Cabal build configuration
+
+## Prerequisites
+
+- [Docker](https://www.docker.com/get-started) (highly recommended for ARM64 toolchain compatibility and reproducibility)
+- Or: [GHC 9.6+](https://www.haskell.org/ghc/), [Cabal](https://www.haskell.org/cabal/), and **LLVM 15** installed with `clang`/`opt`/`llc` binaries mapped to your system path.
+
+## Quick Start (Docker)
+
+1. **Build the containerized environment:**
+
+```sh
+   docker build -t massiv-vs-accelerate .
+```
+
+2. **Run isolated library benchmarks:**
+Pass the specific operation name directly to the container runner to evaluate both libraries back-to-back:
+
+Massiv Stencil Only:
+```bash
+docker run --rm massiv-vs-accelerate stencil-massiv
+```
+Accelerate Stencil Only:
+
+```bash
+docker run --rm massiv-vs-accelerate stencil-accel
+```
+
+3. **Passing Criterion and GHC Runtime (+RTS) Flags:**
+
+Because the container features an automated entrypoint wrapper, you can append reporting flags or memory profiling switches straight to your commands:
+
+```bash
+# Export an interactive HTML chart to your current host directory
+docker run --rm -v $(pwd):/app/out massiv-vs-accelerate stencil --output out/results.html
+
+# Inspect memory allocation and GC productivity profiles (+RTS -s)
+docker run --rm massiv-vs-accelerate stencil-massiv +RTS -s
+
+```
+
+4. **Manual Setup (Without Docker on Mac)**
+Configure dependencies:
+
+Ensure llvm-15 toolchains are [globally](https://www.acceleratehs.org/get-started.html) exposed on your machine.
+
+1. Install llvm dependencies
+
+brew install llvm@15 libffi pkg-config
+
+2. Expose the New Binaries to Your Local Terminal
+```bash
+# 1. Force your active terminal context to prioritize LLVM 15
+export PATH="/opt/homebrew/opt/llvm@15/bin:$PATH"
+
+# 2. Bind development header search flags 
+export LDFLAGS="-L/opt/homebrew/opt/llvm@15/lib"
+export CPPFLAGS="-I/opt/homebrew/opt/llvm@15/include"
+
+# 3. Explicitly link tool locations for the GHC and Accelerate compiler pipelines
+export LLVM_CONFIG="/opt/homebrew/opt/llvm@15/bin/llvm-config"
+export ACCELERATE_LLVM_CLANG_PATH="/opt/homebrew/opt/llvm@15/bin/clang"
+```
+
+Trigger the native build
+```
+cabal clean && cabal build
+```
+Run a benchmark:
+
+```Bash
+cabal run massiv-vs-accelerate -- [map|dot|stencil|stencil-massiv|stencil-accel] [criterion flags]
+```
+Example:
+
+```Bash
+cabal run massiv-vs-accelerate -- stencil
+```
+5. **Benchmark Types**
+- map — Map (+1) over a large array
+
+- dot — Dot product of two large arrays
+
+- stencil — 3x3 mean blur matrix operations comparison
+
+- stencil-massiv — Isolated Massiv stencil loop
+
+- stencil-accel — Isolated Accelerate LLVM backend stencil
