Multiple Cards

To use multiple cards for a single job, the Intel® Manycore Platform Software Stack (Intel® MPSS) needs to be configured for peer-to-peer support (see the Intel® MPSS documentation for details) and the host(s) needs to have IP forwarding enabled.

(host)$ sudo sysctl -w net.ipv4.ip_forward=1

Each host/card should be able to ping every other host/card and the launching host should be able to connect to every target, as with a classic cluster.
