Subject: [Boost-users] [PBGL] Creating graph on multiple processes

Hi!
I am trying to create undirected weighted graph on two mpi-processes. I use
add_edge function to add edges (master (pid=0) process is responsible for
this). For small graphs everything is ok. But when I create larger graphs
(for instance, number of vertices is 2^20 and number of edges is 2^28) the
program hangs supposedly in add_edge. For mpirun -np 1 there is no such
problem.
What can cause this issue? Thanks for any help!
Best,
Alex
