$MX/lib was not in LD_LIBRARY_PATH That is interesting. On the head node, [/etc/ld.so.conf.d]$ more mx.conf /opt/mx/lib But that is not there on the compute nodes. It must have been there before the rebuild. I was looking in /etc/ld.so.con* for things that were getting in my way but not for things that were missing. In any event, adding the $MX/lib to the relevant module takes care of the issue. Thank you... -- Ray Muno University of Minnesota
