 ## Running tests
-The automatic travis tests ONLY run CPU-based tests. Although these cover most of the use cases,
-run on a 2-GPU machine to validate the full test-suite.

-To run all tests do the following:
-
-Install [Open MPI](https://www.open-mpi.org/) or another MPI implementation. Learn how to install Open MPI [on this page](https://www.open-mpi.org/faq/?category=building#easy-build>).

 To test models that require GPU make sure to run the above command on a GPU machine.
-The GPU machine must have:
-1. At least 2 GPUs.
-2. [NVIDIA-apex](https://github.com/NVIDIA/apex#linux) installed.
-3. [Horovod with NCCL](https://horovod.readthedocs.io/en/stable/gpus_include.html) support: `HOROVOD_GPU_OPERATIONS=NCCL pip install horovod`
+The GPU machine must have at least 2 GPUs to run distributed tests.
 
+Note that this setup will not run tests that require specific packages installed
+such as Horovod, FairScale, NVIDIA/apex, NVIDIA/DALI, etc.
+You can rely on our CI to make sure all these tests pass.
 
 ## Running Coverage
 Make sure to run coverage on a GPU machine with at least 2 GPUs and NVIDIA apex installed.
