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.
