Overview

Unified Distributed Execution

The framework supports multiple execution backends: Ray, Dask, MPI and MultiProcessing.

To run tests you need to install pytest package:

pip install pytest

Run tests using command:

pytest unidist/test/

For unidist MPI backend follow additional instructions.

FIX-#91: Add readthedocs config file
Signed-off-by: Alexey Prutskov [email protected]

What do these changes do?

PR adds .readthedocs.yaml configuration file. Only one difference from the main doc building flow is using python3.8 instead of using 3.7 by default. In case of using python3.7 we have documentation built failed because MPI backend in this case requires optional pickle5 package. Updating python version to 3.8 is a way to fix this.
