What is butterfly traffic distribution? about noxim HOT 2 CLOSED

Hi,

You can find a definition of butterfly trafic on Nirgam simulator and then code it similarly on Noxim.
It is defined as:
//////////////////////////////////
int traffic_patterns::trafficButterfly(int tileID, int num_rows, int num_cols)
{

int nbits = (int)log2ceil((double)(num_rows*num_cols));
int dnode = 0;
for (int i=1; i<nbits-1; i++)
    setBit(dnode, i, getBit(tileID, i));
setBit(dnode, 0, getBit(tileID, nbits-1));
setBit(dnode, nbits-1, getBit(tileID, 0));
if (dnode>=num_rows*num_cols)
{
    dnode=num_rows*num_cols-1;
}

return dnode;

}
/////////////////////////////////
This give you the following result in the case of 4x4 mesh 2D:

-1--5--4--8-
-3--2--6--10-
-5--9--13--12-
-7--11--15--14-
-8--4--5--1-
-10--6--2--3-
-12--13--9--5-
-14--15--11--7-

Hoping help you.

Thanks a lot. I plot it out, and it is not like a butterfly.
