Proposals:Condor

Introduction

Condor is an open source distributed computing software framework. It can be used to manage workload on a dedicated cluster of computers, and/or to farm out work to idle desktop computers. Condor is a cross-platform system that can be run on Unix and Windows operating system. Condor is a complex and flexible system that can jobs in serial and parallel mode. For parallel jobs, it supports the standard MPI standard. This Wiki page is dedicated to document our working experience using Condor.

Downloading Condor

Different versions of condor can be downloaded from here. This documentation focuses on our experience installing/configure Condor Version 7.2.0.

Preparation

As Condor is a flexible system, there are different ways of configuring condor in your computing infrastructure. Hence, before starting installation, make the following important decisions.

1. What machine will be the central manager?
2. What machines should be allowed to submit jobs?
3. Will Condor run as root or not?
4. Do I have enough disk space for Condor?
5. Do I need MPI configured?

condor can be installed as either a manager node, a execute or a submit node. Or any combination of these ones. See The Different Roles a Machine Can Play

• Manager: There can be only one central manager for your pool. The machine is the collector of information, and the negotiator between resources and resource request

• Execute: Any machine in your pool (including the Central Manager) can be configured to execute Condor jobs.

• Submit: Any machine in your pool (including the Central Manager) can be configured to allow Condor jobs to be submitted.
