The quoted output is consistent with a system on which InfiniBand headers and libraries were detected at configure time, but no corresponding InfiniBand network hardware is present.  If you are trying to run on a multi-node cluster and believe that InfiniBand network hardware is present, please let us know and we can help determine why the network is not found at runtime.  The remainder of this reply assumes there is no InfiniBand network.

If you are interested only in running on a single host, please try recompiling hello.upc with "--network=smp" to request use of shared-memory communication.

If you are trying to run on a multi-node cluster connected with ethernet, please try recompiling hello.upc with "--network=udp".

If you have some other cluster network, let us know and we can help sort out the best options for you.

If either the "smp" or "udp" network option resolves your problem, then I would recommend that you make it the corresponding network your default.  The best way is probably to return to the configure step in the installation instructions and pass "--with-default-network=NET", replacing "NET" with "smp" or "udp" as appropriate.  Additionally passing "--disable-ibv" will omit the unnecessary support for InfiniBand from the install, but is not strictly necessary.

However, if you cannot reconfigure and reinstall Berkeley UPC (or just do not wish to), then there are other ways to change the default without reinstallation.  You can use an environment variable (UPCC_FLAGS=-network=udp) or a configuration file (add "default_network=udp" to ~/.upccrc).  These solutions are described in more detail at https://upc.lbl.gov/docs/user/upcc.html
