Introduction
Welcome to Condor at the University of Alberta.
This website contains information about the Condor pool of computers
located here at the U of A.
If you can't
find what you're looking for, or have any questions about using the
machines, production schedule, machine availability, or porting your
code, please contact us at research.support@ualberta.ca.
What
is Condor?
Condor
is a system for managing a group of computers. It handles job queueing
and resource allocattion. In particular, it can be used to harvest
unused cpu cycles from a group of computers. At the U of A, we are
starting to use it to make use of the idle cycles in the computer labs
around campus.
For a slightly more detailed introduction to Condor, see this
newsletter article.
Facility Overview
Currently, we have in the condor pool, 60 computers in the ETLC computer lab. These are 2.6 GHz Sun Ultra 20 machines running
a linux operating system with 4 GBytes of memory. However, only 1 GBytes are available to condor. This limits the
applications that can be
submitted to the Condor pool to be those that have been compiled for
the linux operating system. In addition, condor jobs can only run between midnight and 6am.
Condor is set up so that a job will start if there hasn't been a
keyboard or mouse activity for 15 minutes. Once a job starts, if there
is keyboard/mouse activity, the job is suspended until there is no more
keyboard/mouse activity for 5 minutes. If the machine crashes or is
rebooted, the job will be resubmitted again. Because the interactive
user has priority, there is no guarantee of the amount of time
available to the Condor user. To summarize, a program for running on
the Condor pool should:
- be serial
- have an executable for linux
- not have excessive memory or disk requirement
- preferably run within 6 hours
News and Announcements
Current status of the Condor pool will be posted on this page.
The statistics of the Condor pool usage is available here.
The Condor pool is available to any faculty, staff or student of the
University of Alberta. To obtain access, your professor, supervisor, or departmental APO must send an email to idadmin@ualberta.ca, Cc to research.support@ualberta.ca, requesting access on your behalf. For proper identification, the request should include your
name
campus computing id (CCID)
department
student or staff id number
Please feel free to contact Research.Support@ualberta.ca with
any further questions.
If you have applied for access to the numerical
servers or the linux
clusters, then you will already have access to the Condor pool.
