Networking Issues
Application dependent.
Important Parameter is the ratio of communication time
to computation time.
If this is high, it is important to go for an efficient
networking.
Major factors: latency, bandwidth and the topology of
network.
In a typical Gigabit Ethernet network latencies are in
hundred microsecs and sustained bandwidth about 0.5
Gbps.
Wulfkits have a few microsec latency and sustained
node to node bandwidth can be 2 Gbps.
