Yes, but what happens when you run a remote, non-login shell? By that, I mean something like this:
ssh master@ip-10-80-106-70 'echo $LD_LIBRARY_PATH' Assuming I got the syntax right, I suspect you'll find that the contents of the variable, do not include /usr/local/openmpi-1.4.5/lib. You really need that to be in LD_LIBRARY_PATH (or some other method) on all nodes, in all shells for the user. One simple way to do this is via the startup files (eg. .bashrc and .bash_profile for bash, .cshrc for csh/tcsh, etc.) Lloyd Brown Systems Administrator Fulton Supercomputing Lab Brigham Young University http://marylou.byu.edu On 04/25/2012 09:43 AM, seshendra seshu wrote: > Hi > I have exported the library files as below > > [master@ip-10-80-106-70 ~]$ export > LD_LIBRARY_PATH=/usr/local/openmpi-1.4.5/lib:$LD_LIBRARY_PATH > > > [master@ip-10-80-106-70 ~]$ mpirun --prefix /usr/local/openmpi-1.4.5 -n > 1 --hostfile hostfile out > out: error while loading shared libraries: libmpi_cxx.so.0: cannot open > shared object file: No such file or directory > [master@ip-10-80-106-70 ~]$ mpirun --prefix /usr/local/lib/ -n 1 > --hostfile hostfile > out > > > out: error while loading shared libraries: libmpi_cxx.so.0: cannot open > shared object file: No such file or directory > > But still iam getting the same error. > > > > > > On Wed, Apr 25, 2012 at 5:36 PM, Jeff Squyres (jsquyres) > <jsquy...@cisco.com <mailto:jsquy...@cisco.com>> wrote: > > See the FAQ item I cited. > > Sent from my phone.
