Installed Math Libraries

The following libraries are now installed under /opt

Libraries and the VNFS

Because the cluster uses a RAM disk (VNFS) boot scheme, all math libraries are mounted under /opt. The /opt is NFS mounted on all nodes. In cases where programs require shared libraries, they can be accessed over NFS. However, it is best to statically link these libraries instead of using shared libraries. There will be no performance impact due to static linking and in some cases performance my be slightly better.

If you are using dynamic linking (shared libraries), then you should make sure you set your LD_LIBRARY_PATH to the appropriate library path in your .bashrc or .cshrc file.
