I looked further into this uDAPL thing and found an FAQ: http://www.open-mpi.org/faq/?category=udapl This one was particularly interesting: 3. Where is the static uDAPL Registry found? Solaris: /etc/dat/dat.conf Linux: /etc/dat.conf On my CentOS installation, I have two, neither of which is where it's supposed to be for "Linux" in the opinion of open-mpi.org. $ locate dat.conf /etc/ofed/dat.conf /etc/ofed/compat-dapl/dat.conf /usr/share/man/man5/dat.conf.5.gz Would there be a way at the time of compiling Rmpi to specify a configure arg to use one or other of the ones I have? Or would it be simpler to make a link in /etc/ to one or other of them? Is there any danger that such a link could bother anything else? best -- ~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~. ___ Patrick Connolly {~._.~} Great minds discuss ideas _( Y )_ Average minds discuss events (:_~*~_:) Small minds discuss people (_)-(_) .....
