[boost] Open-MPI with Boost.MPI

Hi, I would like to know if there is any recommended version of Open-MPI to be used with Boost.MPI. I was looking for existing libraries for Boost.MPI for download but could not find any -- if anyone has any pointers to the same that would be really very appreciated. Currently, I have Open-MPI v1.5.1 in my XP box. Thanks and Regards, Arpan
