Hi All, I have been trying to solve the problem mentioned in my earlier mail below. As i tried to figure out why certain topologies do not work, i found something which doesn't make sense to me.
As i mentioned earlier, i am able to receive messages for complete topologies (say of 10 nodes). For this i run my program as follows ./build/pc/main.exe 10 > result.out Now i created a .nss file (say topo10.nss) of 10 nodes where each node can communicate with every other node (again a complete topology).The topo10.nssfile looks like this 0:1:0.0 0:2:0.0 . . . 9:8:0.0 I run my program using this file as input as follows ./build/pc/main.exe -rf=topo10.nss 10 > result.out What i found is that in the latter case again nodes do not receive messages while they do in the former. This actually sounds wierd to me so i tried it again but i get the same result. Has anyone faced a similar problem? Am i making some errors with the .nss file? Can anyone please please help me ?
