Hi,
Thanks for the prompt reply. This might be basic but typically where is the 32 bit ofed libs? I think the default install prefix is /usr and my guess is the 64 bit libs is in /usr/lib64 . Where do I look for the 32 bit ofed libs? I remembered during the ofed build that passing 32 bit build argument failed - will it still install an OFED 32 bit libs?
