Hi,
I am using the C package for igraph-0.5.3
I want to create a large random graph, using erdos_renyi_game GNP:
N ~ 262144
P ~ 0.5
I am getting a memory error in vector.pmt
I have a 64 GB machine, and I dont think I can add to the memory any more. Can
I reduce the number of bytes used by an edge and a vertex?
In any case I would like to generate a graph that is a group of erdos-renyi
graphs, with the groups connected randomly. There would be of the order
of 1000 nodes in each group and 256 groups.
I was trying to create an adjacency matrix, and then use it to create a graph.
But that seems wasteful, any suggestions?
Thanks in advance for the help,
Raghav
