DASF is an Accelerated and Scalable Framework

DASF is a generic framework specialized in acceleration and scaling common techniques for Machine Learning. DASF uses most methods and functions from the most common libraries to increase the speed up of most algorithms. Part of this is to use Dask data to scale computation and RAPIDS AI algorithms to extend the support to GPUs as well.

Installation

For now, the installation can be done using docker or singularity (if available).

Containers

To install DASF using docker or singularity, you must go to the build/ directory and execute the command below directory according to your build type: cpu or gpu. Notice that DASF uses HPC Container Maker (HPCCM) to generate recipes for all sorts of container types. You should install HPCCM first, in order to generate them.

./build_container.sh --device <cpu|gpu>

You can also configure other parameters of the container if you want. Run -h for further information. It includes the container backend: docker or singularity.

The dasf image will be created and ready to use. Once it is ready, you can start a jupyter instance by executing the command:

./start_jupyter_server.sh --device <cpu|gpu>

You can also define a different port by using --port PORT argument.

Install

To install this development version, all you need to do is run pip from the root project directory (the same where pyproject.toml lives).

pip3 install .

Examples

If you want to see some examples of how to use DASF, you can visit the tutorials page to get more information of basic and advanced usage.

Testing

If you have a working environment with DASF installed, you can execute all the test sets. Make sure you have all development packages installed such as pytest, parameterized and mock. To run, you need to execute pytest from the tests/ directory.

pytest tests/
