Hi,
I could run the benchmark Graph Analytics, but I could not understand the
output. I had this output:
piabanha{127} ./tunkrank --powerlaw=10000000 --ncpus=2 --engine=asynchronous
GRAPHLAB_SUBNET_ID/GRAPHLAB_SUBNET_MASK environment variables not defined.
Using default values
Subnet ID: 0.0.0.0
Subnet Mask: 0.0.0.0
Will find first IPv4 non-loopback address matching the subnet

Could you explain me this output? What does the --saveprefix arg files has when
I use this option?
Best,
Alexandre
