NTPoly now uses Travis CI to perform contiguous integration. We’ll still perform local regular compilation tests, since Travis CI doesn’t provide every possible environment (for example, Intel clusters). However, hopefully this will help us catch bugs easier, and make it easier to perform pull requests.

One of the main challenges I faced when adding Travis CI support was setting up newer versions of libraries. NTPoly requires MPI version 3, as well as up to date versions of Swig and Cmake. Unfortunately, those don’t come by default in the Travis CI environment. This means that currently we have to install some libraries from source, which makes the integration tests very slow. In the future, hopefully we can use something like docker to speed up this process.
