# Readme


This is the basic centralized set of benchmarks for
[OmpSs-2@Clusters](https://github.com/bsc-pm/nanos6/blob/master/docs/cluster/README-CLUSTER.md).

## Installation

Right now it requires a set of dependencies and requirements to
work. We will try to reduce the dependencies as much as possible in
the future.

1. [OmpSs-2@Clusters
requirements](https://github.com/bsc-pm/nanos6/blob/master/docs/cluster/README-CLUSTER.md#system-requirements).

2. [Mercurium](https://pm.bsc.es/mcxx)

3. [Nanos6](https://pm.bsc.es/ftp/ompss-2/doc/user-guide/build/nanos6.html)

4. [Liberep](https://pm.bsc.es/gitlab/nanos6/liberep) (Avoid to use this; it will be removed in the near future)

To build the code you need first to install all the dependencies above. Then just:

```console
git clone --recursive 'url_to_this_repo'
cd nanos6-cluster-benchmarks
mkdir build
cd build
cmake ..
make
```

After this all the benchmarks should be build inside a directory with
the same name than the original one in the project's root directory.

## Adding benchmarks

To add a new benchmark you only need to create a new directory inside
the project's root directory and add a CMakeLists.txt within it with
the build instructions.

You don't need to modify anything in the main CMakeLists.txt or
anywhere else outside that directory. If you want to add similar
benchmarks that reuses some code between them you can add them in the
same directory.

### Contribution hints

1. Please try to rely in the **utils** functionalities when possible
   instead of using external no standard tools.

2. Make the benchmarks keeping readability and simplicity as much as
   possible (read [The Zen of
   Python](https://www.python.org/dev/peps/pep-0020/) or execute
   `python -c 'import this'`).
   
3. You can use C (.h .c) and C++ (.hpp .cpp) mainly, please respect
   the filenames.
   
4. Use the [linux kernel coding
   style](https://www.kernel.org/doc/html/v4.10/process/coding-style.html).
