Serves me right for not reading your original mail.... you have SLES 11 SP2
The openmpi RPMs are provided by the SuSE Software Development Kit DVD. you can download SIO images of this from the SUSE website. For SP! it is named SLE-SP1-SDK-DVD-x86_64-GM-DVD1.iso So you should copy this .iso file onto your system - the SP2 version of course. Use YAST to enable it as a software repositoty, or use zypper -ar to add it as a repository zypper search openmpi zypper install openmpi I have bored this list enought with Suse stuff - send me an email if you cannot get the above recipe to work.
