Hi!

I have a problem with Beamer BFS benchmark. It looks to be broken: it seems to work but the final results are always zero (bfs_nedge etc.). All other BFS implementations (SPMD and Queues) are Ok.

srun --cpu_bind=rank --label --kill-on-bad-exit --nodes=4 --ntasks-per-node=2 --time=15:00 \ ./applications/nativegraph/bfs/bfs_beamer.exe --scale=22 >&1

If anybody can help me, that would be wonderful or I will look into it as soon I have time.

Best,
Alex

p.s. I am wondering where are my \n in output (code) section?
