How to configure a cluster with partial Infiniband connection.


Suppose you have a logical MOSIX cluster that consists of two physical clusters, each connected by both Ethernet and Infiniband, but the physical clusters are only connected between them by Ethernet: First configure the nodes within each physical cluster (including the local node) by their Infiniband IP address and the nodes in the other physical cluster by their Ethernet address.

Next, using "mosconf", select:   "1. Which nodes are in this cluster",

then type "+" to turn on the advanced features,

then type "a" to define aliases and for each node in the other cluster, define its Inifiniband IP address (despite being unreachable from the node that is being configured) as an alias to its Ethernet IP address.
