There is a problem with this philosophy. We provide hwloc on our machines in a network filesystem at a unique path. All machines have OFED installed, but some miss ibverbs. When building hwloc on a machine with ibverbs, then things will not work on machines without ibverbs. So I guess choice via configure is better. See attachments, if you are interested (based on hwloc-1.0.2(stable)). > Brice > -- Dr. Bernd Kallies Konrad-Zuse-Zentrum für Informationstechnik Berlin Takustr. 7 14195 Berlin Tel: +49-30-84185-270 Fax: +49-30-84185-311 e-mail: kall...@zib.de
