I am more interested in batch and Hadoop clusters than Beowulf or Mosix for now. OSCAR is a single-system image (SSI) tool, similar to Beowulf or OpenMosix.

I have a little problem with the network, I'm using CentOS on the master node, but I have two nodes, with Fedora and Ubuntu, respectively. No problem if the nodes are with different OS? I wonder also how to configure the network, having a public network adapter and one for the cluster's private network with the nodes and the master node. Thank you.

I have a little problem with the network, I’m using CentOS on the master node, but I have two nodes, with Fedora and Ubuntu, respectively. No problem if the nodes are with different OS?

I wonder also how to configure the network, having a public network adapter and one for the cluster’s private network with the nodes and the master node.

Thank you.

I would not expect a graphics card to have a MAC address unless you could also plug a network cable into it. So changing a graphics card should not change MAC addresses unless maybe you also reorder some PCI or PCIe network adapters also. In that case the order of MAC addresses may change from what linux was configured for.
