Jeff may be a little too harsh here. The XRC compilation problems only show up if one configures with some non-default options (--enable-static or --disable-dlopen). My recommendation is to install 1.6 and 1.7 (and eventually 1.8). If you don't think you have the resources, then consider... I am a user on a system (also iDataPlex, but that is irrelevant) that has stuck with Open MPI 1.4.x since it was deployed. Since the admins have never installed a 1.5, 1.6 or 1.7 version, we instead have MULTIPLE user-built copies of Open MPI on the system, with potentially different configuration options and, of course, in "random" locations within /home. Our admins want "stable" and the users want "speed" and/or "features". Keeping both happy requires more than one version be installed. -Paul -- Paul H.
