So, right now OSCAR doesn't explicitly help you push shared libraries out to the compute nodes (as opposed to a system like Scyld). However, we do provide some tools that allow you to do this. It sounds like you've attempted to do the two things that are needed: pushing the libraries out and setting up your environment. As you are still seeing problems, there are really two possiblities: The libraries aren't out there or your environment is set up incorrectly. Checking to see if the libraries are out on the nodes is pretty easy - log into the nodes and run ls <where ever you think the libraries should be. Checking your environment is a tad bit more difficult. Remember that not all dot files are run in non-interactive logins. So you can't just log into the remote node and run printenv LD_LIBRARY_PATH. Instead, you have to login non-interactively and have it spit your environment back at you. Something like: ssh <compute node> 'echo $LD_LIBRARY_PATH' should work. The quotes are important - otherwise $LD_LIBRARY_PATH will be evaluated by your local shell and everything will go down hill from there. If both of these conditions are met, you might want to talk to PGI - at that point, this isn't an OSCAR problem. One other point (as if this e-mail isn't long enough already). If there are multiple users on the system, you may find it simpler to modify /etc/ld.so.config and add /usr/pgi/lib to the system library path. Then run ldconfig on all your nodes to update the shared library system. cpush and cexec will most definitely be your friends on this one.
