Measurements using a synthetic job trace show that self-organized flocking reduces the maximum job wait time in queue for a heavily loaded pool by a factor of 10 compared to without flocking. ... This paper presents a technique for resource discovery in distributed Condor pools using peer-to-peer mechanisms that are self-organizing, fault-tolerant, scalable, and locality-aware. ... CONCLUSION We have presented a locality-aware p2p approach to remote Condor pool discovery, which yields a self-organizing flock of Condor pools. ...doi:10.1145/1048935.1050192 dblp:conf/sc/ButtZH03 fatcat:lgnreeeof5gifchwfpq4wwnccm
In this paper, we present a novel approach that integrates a self-organizing P2P overlay for scalable and timely discovery of resources with unmodified client/server job scheduling middleware in order ... To verify the practicality of PonD, we have implemented a prototype using Condor (called C-PonD), a structured P2P overlay, and a PonD creation module. ... To overcome the pre-configuration requirements of condor flocking, Butt et al.  presented a self-organizing Condor flock that was built upon a structured P2P network. ...doi:10.1145/2287076.2287105 dblp:conf/hpdc/LeeWF12 fatcat:3cqvukk4ffffta4s2czakngbtu
So the need arises to extend the Condor load-sharing and protection mechanisms b e y ond the boundaries of Condor pools, or in other words, to create a ock of Condors. ...

Voluntary grids introduce a host of issues to tackle, most importantly getting users involved quickly. ... A shortcoming of such systems is that most users are often limited to contributing resources and few users are capable of developing or porting their own applications in order to use these resources. ...
