Out of curiosity, have any of the OpenMPI developers tested (or care to
speculate) how strongly affected OpenMPI based codes (just the MPI part,
obviously) will be by the proposed Intel CPU memory-mapping-related kernel
patches that are all the rage?

Well, it appears from that article that the primary impact comes from accessing
kernel services. With an OS-bypass network, that shouldn’t happen all that
frequently, and so I would naively expect the impact to be at the lower end of
the reported scale for those environments. TCP-based systems,

Have you tried the toolchain from linaro ?
