The concept of Atom

User 67 | 2/28/2014, 5:48:56 AM

Hi all,

May I know how atom is implemented in the case of distributed graph? I am aware that an atom is single compressed journal. How is this compressed journal generated and at what point of the distributed graph generation, are we using this feature?

Thanks and Regards, Sai Sagar.J

The Atom mechanism is no longer used in graphlab. This would be from the paper "Distributed GraphLab: A Framework for Machine Learning in the Cloud. VLDB 2012". We have a follow up paper with a new partitioning mechanism described in "PowerGraph: Distributed Graph-Parallel Computation on Natural Graphs. OSDI 2012"
