Title:	BUILDING DISTRIBUTED, WIDE-AREA APPLICATIONS WITH WHEELFS


Speaker:	JEREMY STRIBLING (M.I.T.)


ABSTRACT:

It is a challenge to build applications that need to share data and are 
distributed across hundreds or thousands of computers in a wide-area 
network (e.g., PlanetLab or on a Grid).  In order to cope with high 
latency, throughput bottlenecks, and temporary failures, such applications 
typically implement their own storage plan or use special-purpose storage 
solutions (e.g., DISC, Globus, Carbonite, etc.).  Inspired by the success 
of the Google File System for cluster applications, this proposal 
investigates whether a general-purpose wide-area file system could 
simplify building distributed applications.  In particular, this talk 
presents a preliminary design, called WheelFS. WheelFS's goal is to ease 
the development of distributed applications such as cooperative Web 
caches, data-intensive Grid applications, and PlanetLab measurements, 
perhaps reducing the storage management code to a simple script around the 
application's core logic.  Towards this goal, WheelFS adopts many features 
from existing file systems, and adds two new ones: semantic cues, and 
write-locally-read-globally.  This talk will also discuss several specific 
applications that can potentially benefit from using WheelFS.
