A very very fast algorithm for analyzing graphs on disk using a single computer
Mosaic: processing a trillion-edge graph on a single machine. Faster than a cluster of computers.
These computations are for analyzing data off-line, and not for real-time queries. But the results can be later cached.
Apply known analysis to a grapd DBMS on disk at a speed comparable to a cluster of computers.
They are off-line analysis.
