Re: Board report

Thanks Owen. Any one else have thoughts? Status report for the Apache Giraph project - July 2012 Giraph is a Bulk Synchronous Parallel framework for writing programs that analyze large graphs on a Hadoop cluster. Giraph is similar to Google's Pregel system. Project Status --

Announcing: Green-Marl/Giraph

Hi everyone, Some of you might already know Green-Marl, Green-Marl compatibility was even mentioned as a new feature for Giraph 0.2, but for those who don't, let me give you a quick introduction. Green-Marl is a domain-specific language tailored to graph algorithms. It has many features that

Re: Announcing: Green-Marl/Giraph

Nice to know about `Green-Marl`. Abstraction would make working with Graphs more easy, but also would also add a bit of a performance overhead. Has any study been done on the same? Thanks, Praveen On Wed, Jul 11, 2012 at 7:40 AM, Avery Ching ach...@apache.org wrote: This is really cool stuff.

Re: Announcing: Green-Marl/Giraph

Hello Praveen, This very much depends on the algorithm. Due to some recent optimizations (intra-loop merging) many algorithms should be as fast as hand-implemented code. Publications on this subject are in preparation. The only Giraph feature we do not currently use is combiners, but we are
