چکیده
Condor is a “specialized workload management system for compute-intensive jobs.” Compilation of 3 areas of research Analysis of workstation usage patterns Who are using these workstations? How often are they free? Remote capacity allocation algorithms How do we allocate jobs? Who gets pushed to the top of the queue? Development of remote execution facilities What is the best way to run a job on a remote machine? How can we stop a job midway when the machine is no longer idle? System Design

A worldwide flock of Condors: Load sharing among workstation clusters
Condor is a distributed batch system for sharing the workload of compute-intensive jobs in a pool of Unix workstations connected by a network. In such a Condor pool, idle machines are spotted by Condor and allocated to queued jobs, thus putting otherwise unutilized capacity to e cient use. When institutions owning Condor pools cooperate, they may wish to exploit the joint capacity of their pool...
متن کاملBuilding a secure Condor pool in an open academic environment
The Condor system ([1], [2]) is a widely used “cycle scavenging batch scheduler” which is increasingly being used to utilise the “idle time” of workstations in so-called “campus grid” installations across the UK, yet its security architecture is not well suited to such environments. In this paper we describe how a campus grid Condor installation at the University of Cambridge has addressed the ...
متن کاملCurrent methods for negotiating firewalls for the Condor system
The Condor system is a widely used “specialized workload management system for computeintensive jobs” [1] which is increasingly being used in UK academic environments to utilise the socalled “idle time” of workstations. Due to Condor’s pattern of network communication there are a number of issues that arise when Condor is deployed across firewall or private network boundaries. In this paper we ...
متن کاملHands - On Experience with Condor , the Advanced Load
These days UNIX workstations are common in both the academia and the industry. It is very seldom the case that a computer engineer or a computer scientist does not have a UNIX workstation sitting on her/his desk. The users of those workstations often fall under one of two overlapping categories. The rst is an administrative user who works on email, paper preparation , code development and debug...
متن کاملMaking Workstations a Friendly Environment for Batch Jobs
As time-sharing machines are replaced by powerful desktop computers and farms of workstations replace mainframes, more and more users turn to workstations when they need CPU cycles for their batch jobs. Unfortunately, they do not find workstations a very friendly environment for batch processing. Since these types of machines were originally designed as a single user environment, they lack most...
