# Compile and Running HowTo
This is a collection of scripts and configuration that would
allow to compile and run the benchmark in a consistent way
The following will clone, and compile all the stuff
```bash
git clone https://gitlab.arif-ali.co.uk:8543/arif/raspberrypi-hpl
cd raspberrypi-hpl/scripts
./compile_all.sh
```
First clone the repository
Then we can run the benchmark using the following script
git clone https://gitlab.arif-ali.co.uk:8543/arif/raspberrypi-hpl.git
```bash
./run_job.sh
```
Change to the scripts directory
cd raspberrypi-hpl/scripts
You will find many scripts, and a `CONFIG` file. The one script will compile everything for you, i.e. by running the following command
./compile_all.sh
If at any time any of the parts fail, you can run the individual `make_*` scripts
In order, the `compile_all.sh` will compile the applications in the following order
1. mpich
2. OpenBLAS
3. HPL
If for any reason you need to change any of the compilation flags or options, you can either udpate them in the `CONFIG` file or the corresponding `make_*.sh` script. For HPL, you will need to update `config/Make.rpi4_mpich` for any extra flags that you may require
Finallu, once you're happy that the relevant applications have compiled, then we can run HPL using the following command
./run_job.sh
