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.
