# Parallel Data Processing with MPI

In this repository, we aim to use [open-MPI](https://www.open-mpi.org/doc/) to realize parallel 

data processing. This repo includes 3 tasks implemented with `cpp`:

- Calculate Pi

- Count prime numbers

- Accelerate MatMul

Please check the `README` in each folder for more details.

## Installing MPI

### Automatically

For Ubuntu, you can find `mpich` [here](https://packages.ubuntu.com/focal/mpich).

```shell

$ sudo apt-get install mpich

$ sudo make install

```

For MacOS, you can simply install `mpich` with homebrew

```shell

$ brew install mpich

```

Please Note that in each `CMakeLists.txt` file, you need to change the `CMAKE_CXX_COMPILER` to your

`mpicxx` path. 

```cmake

set(CMAKE_CXX_COMPILER "/usr/local/bin/mpicxx") # MacOS

set(CMAKE_CXX_COMPILER "/usr/bin/mpicxx") # Ubuntu

```

### Manually

Or manually download and compile `mpich`

```shell

$ wget https://www.mpich.org/static/downloads/4.0/mpich-4.0.tar.gz

$ tar -xvf mpich-4.0.tar.gz

$ ./configure

$ make

```

If `mpich` is manually installed，we need to configure `MPI_ROOT` 

```shell

export MPI_ROOT=$BUILD_DIR

export PATH=$MPI_ROOT/bin:$PATH

export MANPATH=$MPI_ROOT/man:$MANPATH

```

`$BUILD_DIR` is the directory where you compile `mpich`

Please Note that in each `CMakeLists.txt` file, you need to change the `CMAKE_CXX_COMPILER` to your

`mpicxx` path.

```cmake

set(CMAKE_CXX_COMPILER "YOUR_BUILD_PATH/mpicxx")

```
