I would also like to implement support for CDash.

I use CMake for building and testing Boost.MPI. Not sure I added the last tests to the b2 framework.

This implies that MPI is not fully tested for release.

It's never been, at some point b2 did not support some versions of Intel MPI, so all these were dropped. I was answered that "this is an Intel problem", which was true, but not helpful. Some other MPI implementation had their own issues. Depending on the cluster configuration, I need to switch between mpirun, mpiexec, srun etc... I'm sure it can be done with b2, but I don't even know where to start. I can't even find where the b2 MPI test launcher is located. And it's not widespread to the point that people will be likely to address these problems.

Hmmm ... Better in what way? They should produce the same result or close to it. My problem with B2 is that its complex, hard to understand, a lot of work to maintain and fragile.

I wondered what makes b2 so complex compared to CMake, so I opened two files from your project: one for b2 build, and another for CMake build https://github.com/boostorg/safe_numerics/blob/develop/test/Jamfile.v2 https://github.com/boostorg/safe_numerics/blob/develop/test/CMakeLists.txt

I find them difficult to write, not to read. - Alain
