Unfortunately I haven't seen the above issue, so I don't have a workaround to propose. There are some issues that have been fixed with GCC-style inline assembly in the latest Sun Studio Express build. Could you try it out? http://developers.sun.com/sunstudio/downloads/express/index.jsp -Ethan > Does anyone have any insight as to how to successfully > build OpenMPI for this OS/compiler selection?
