New Task - Network latency
There is a new task:
9- Measure Network latency.
Mandatory: Global Brokers should exchange messages in order to calculate the network latency between them. This may be done by using a udp request or by ping:
'ping -c $1 141.109.37.173 | tail -1 | cut -d = -f 2 | tr -d ms | tr -d " " | cut -d \/ -f 2'
Wish list:
Add bandwidth measures between Local Broker and the Global Broker and between the Local Broker and the Scheduler.
This way, it is possible to extract measures that represents all computers in the Grid environment.

For Tuesday Nov 06, 2007
- items: 2, 3, 4 (full), 5.1, 5.2.3, 5.2.4 and 9
- wish list: 5.2.5
To use the memory benchmark.
First, use the benchmark with only the Main Memory.
Then use it with following sum: (Free Main Memory + Free Swap Memory).
The memory increment is defined by (FreeMem + Swap)*0.05
This is the line that should be used:
./build/memo [(memfree+swapfree)*0.9] [arg_incremento] | awk '{ print $2" "$8; }' > saida; ./test2.sh saida [memfree]
Script file modified.
Now, working on the mmq.c in order to adjust its input.
I'm going to rewrite all of it. The difference will be: first line of the input is the order, the rest of the file is the input data.
