Hi Gavan,

Giraph can run on a single machine as well as multiple machines, just like Hadoop. Our test suite can be run with or without a running Hadoop instance as an example.

If you want to take advantage of multiple cores though, you might want to try running Hadoop with multiple map slots on the single node and then using the appropriate number of workers.

Hope that helps,

Hi all,

I know the focus of giraph is multiple machines etc....

What if I want to scale down to single pc/ multiple cpu's and even down to embedded systems.

Is this project and hadoop able to scale down as well as up ?
