Hello Marcin What configure options are you using besides with-libfabric?
Could you post your config.log file tp the list? Looks like you only install fi_ext_usnic.h if you could build the usnic libfab provider. When you configured libfabric what providers were listed at the end of configure run? Maybe attach config.log from the libfabric build ? If your cluster has cisco usnics you should probably be using libfabric/cisco openmpi. If you are using intel omnipath you may want to try the ofi mtl. Its not selected by default however.
