Motives
AdvantagesDecreased wait time for builds
Introduction
Our System is
Based on Coord, open source for distributed environment of NHN
Faster time-to-market
Complex and massive softwares
Very long compile time
Idle low spec machines

A space-based architecture built on distributed hash tablesSBA(Space-based Architecture) –processes communicate with others thru. only spaces
DHT(Distributed Hash Tables) –data identified by hash functions are placed on numerically near nodes
A computing platform to project a single address space on distributed memoriesAs if users worked in a single computing environment
Coord
What Is Coord
Simple APIswrite: write an objectread: read a copy of an objecttake: read an object & delete it
Coord = SBA + DHTsimple to use scale well to large numbers of nodes locate data with low latencybalance the distribution of data evenly amongst the participating nodeshandle node join/leave scalablyease the maintenance of per-node routing Tables

Coord Applications
Provide inter-process communication, resource share, and synchronization thru. the space
Support a variety of distributed programming models with only simple API(write/read/take)
Proper for general-purpose distributed programming as well as data-/computation-intensive distributed programming
Coordhides some complicated codes for network programming
The peers don’t need to recognize each other since Coordprovides time-/location-decoupling
What Is Coord
Client-Server
Master-Worker -provide a scalable framework for parallel processing
Scatter-Gather -provide an on-the-flyframework for data exchange
Map-Reduce -provide a simplified framework for massive data processing

Master-Worker ModelInstantiate a virtual space
Set some keysa key to write/take jobs
different keys to take/write results
