\"Condor\" name changing to \"HTCondor\"
In order to resolve a lawsuit challenging the University of Wisconsin-Madison’s use of the “Condor” trademark, the University has agreed to begin referring to its Condor software as “HTCondor” (pronounced “aitch-tee-condor”). The letters at the start of the new name (“HT”) derive from the software’s primary objective: to enable high throughput computing, often abbreviated as HTC. Starting in the end of October and through November of this year, you will begin to see this change reflected on our web site, documentation, web URLs, email lists, and wiki. While the name of the software is changing, nothing about the naming or usage of the command-line tools, APIs, environment variables, or source code will change. Portals, procedures, scripts, gateways, and other code built on top of the Condor software should not have to change at all when HTCondor is installed.

More secure configuration for PostgreSQL and Quill documented
When Quill was first developed, it was designed to work with older versions of the PostgreSQL database server. Newer versions of PostgreSQL have stronger security features, which can be enabled in the PostgreSQL configuration, requiring no changes to the Quill daemon. We recommend that all Quill sites upgrade to the latest version of PostgreSQL (8.2), and make these easy changes to their PostgreSQL configuration. The consequences of not doing so mean that any user who can sniff the network between the Quill daemon and the PostgreSQL server can obtain the Quill database password, and make changes to the Quill database. This can change the output of condor_q and condor_history, but cannot otherwise impact Condor’s correctness or security. Otherwise unauthorized users cannot use this database password to run jobs or mutate Condor’s configuration. A second problem with the previously recommended configuration was that any user with the publicly-available read-only Quill PostgreSQL password could create new tables in the database and store information there. While this does not effect the running of Condor in any way, sites may view that as a security problem. As of Condor 6.8.6 and 6.9.4, the Condor manual has been updated to describe the more secure installation of PostgreSQL, which remedy both of the above problems. These changes include the following: Change the authentication method (the final field) in the pg_hba.conf file from “password” to “md5”. Restarting PostgreSQL is then needed for this to take effect. Only allow the quillwriter account to create tables. To do this, run the following two SQL commands as the database owner. REVOKE CREATE on SCHEMA public FROM PUBLIC; GRANT CREATE on SCHEMA public to quillwriter;
Durham University Department of Geography flies with Condor
In 2006 the Durham University Department of Geography began examining ways of increasing the speed at which research results could be obtained from geophysical modelling simulations. After a period of testing lasting over 6 months, the Department of Geography has successfully implemented a distributed computing system built upon the Condor platform. Since its implementation, the Condor distributed computing network has provided a unique facility for spatial modelling which is particularly suited to Monte Carlo approaches. Thanks to the processing power offered by the Condor network, members of the Catchment, River and Hillslope Science (CRHS) group have developed methods of ultra-high resolution image processing and remote sensing which are pushing the traditional boundaries of ecological monitoring at both catchment and local scales.

"UW Condor project is a piece of CERN's massive grid computer"
at the Wisconsin Technology Network. “The University of Wisconsin’s Condor software project will provide a component of a cutting-edge grid computing system at European research heavyweight CERN, the IDG news service reports.” “After finding no commercial grid applications that satisfied all its needs, CERN took to cobbling together a system from a variety of sources, starting with the Globus Toolkit from the Globus Alliance and using the Condor project’s scheduling software.”

We recently held our annual Condor Week conference. A survey for attendees, photos, and presentations are now all available for your perusal.
"CERN readies world's biggest science grid"
in Computerworld. “Instead, CERN based its grid on the Globus Toolkit from the Globus Alliance, adding scheduling software from the University of Wisconsin’s Condor project and tools developed in Italy under the European Union’s DataGrid project.”
Hartford Life is in the news
The Hartford Financial Services Group is doing very well with Condor. See “Grid Computing At Hartford Life” by Tammy J. McInturff in the LOMA newsletter.” Also, see “Analyze This”, by Steve Dwyer, (in Insurance Networking News) mentions the Hartford Financial Services Group’s deployment of Condor. “‘Prior to the grid initiative, we had hit a ceiling with the level of horsepower we could deploy in running calculations through servers and desktops,’ says Severino.” And, in December 2004, see “Mother of Invention ”, by Anthony O’Donnell, (in Insurance & Technology magazine) describes the Hartford Financial Services Group’s deployment and use of Condor. “The [Condor] grid solution ‘is actually more robust,’ [CIO Vittorio Severino] says. ‘The value is, No. 1, it just creates capacity; No. 2, it’s a more stable environment; and then, No. 3, we enjoy the obvious cost savings.’”
An eagle-eye view of the Condor project
This article by Jeff Mausolf is on IBM’s developerWorks web site. “Condor addresses both of these problem areas by providing a single tool that can manage a cluster of dedicated compute nodes and effectively harness otherwise wasted cycles from idle desktop workstations.”
"Using the GRID to improve the computation speed of electrical impedance tomography (EIT) reconstruction algorithms" (PDF) in Physiological Measurement"
Authors Fritschy, Horesh, Holder, and Bayford presents an improvement to image quality generation (using Condor), that make clinical use of the images more practical. “Using the GRID middleware “Condor” and a cluster of 920 nodes, reconstruction of EIT images of the human head with a non-linear algorithm was speeded up by 25-40 times compared to serial processing of each image.”

Condor "Setup Hawkeye" package is available
Version 0.1.0 of the Condor “Setup Hawkeye” package is now available. We’ve been getting an increasing stream of requests to make it easier to add Hawkeye features to your existing Condor. To solve this problem, we’ve created the above package which modifies your Condor configuration & installs the same “install module” script as is used in Hawkeye (except that here it’s named condor_install_module instead of hawkeye_install_module). You can then download & install the same modules as you can for Hawkeye, and can then use the dynamic attributes in your Machine Ad for match-making purposes. More details are available through the Hawkeye page
NeST 0.9.6 released
NeST version 0.9.6 has been released and is available for download.

The annual Condor meeting will take place as part of Paradyn-Condor week at the Fluno Center on University of Wisconsin, Madison campus on April 14th-16th, 2004. You can learn more on the conference web page.
Condor-Users mailing list opened!
A new mailing list for condor users has been added. The Condor Users mailing list is designed to bring the Condor user community together to share ideas, problems, and solutions. It is meant to supplement, but not replace, our existing support channels.
Condor is going open source!
The usage license for Condor has changed to the Condor Public License, a very liberal license that permits installation, use, reproduction, display, modification and redistribution of Condor, with or without modification, in source and binary forms. This license has already been applied to the binary downloads for Condor version 6.4.7 for both UNIX and Windows. The Condor Team is busily preparing the source code for public release under the terms of the Condor Public License as well. Stay tuned!
Condor-G included in NMI version 2.1

Linux Kernel Bug Touched By Condor!
The default Linux kernel shipped with Red Hat 6.2 contains a bug which Condor can trigger. This would cause Red Hat 6.2 machines running Condor to hang. All Red Hat 6.2 users should either upgrade their kernel to 2.2.16 or later, or upgrade to Condor Version 6.1.15, which will be out early the week of 8/21/00.
Fortran bugs found in version 6.1.11 for Solaris and IRIX
Condor version 6.1.11 contains bugs in the way we handle certain system calls that are used by Fortran. This is a problem particularly on Solaris and IRIX, though other platforms might have problems as well. We will release a new version shortly that corrects these problems. If you are only using vanilla jobs, this should not effect you. If you do not relink your jobs with condor_compile using the 6.1.11 libraries, you will also not have this problem (though you also won’t be able to use many of the new features in 6.1.11).
Condor in the news!
Condor has been mentioned in NCSA Datalink, in the January 2000 edition, as well as NAS News: NAS Condor Population Expands to Hundreds.
condor_status bug in 6.1.10 found
Condor version 6.1.10 contains a minor bug in the condor_status program. For some sites, this causes condor_status to have a segmentation fault, be killed by SIGSEGV, and to drop a core file when trying to display the totals at the end of condor_status. If you are upgrading to 6.1.10 from a previous version, please save your old condor_status binary and install that into your Condor bin directory once you have completed your upgrade. Version 6.1.11 will fix this bug.
Checkpointing bug in Condor Version 6.1.9
Condor 6.1.9 contains a bug in the checkpointing code for “standard” jobs. Once a job checkpoints for the first time, it will no longer be able to checkpoint again. If you are using the standard universe (relinking your jobs with condor_compile), you are going to have problems with 6.1.9. A new version will be released very soon to fix this bug.
A Preview version of Condor for Microsoft Windows NT 4.0 is now available!
The initial version of Condor NT is now available on the downloads page.
The Condor Manuals are now available from the Mirror Site!
The Condor Version 6.0 and Version 6.1 manuals, in several formats, are available for download from the Madison, WI, USA or Bologna, Italy sites.

Use of MemoryRequirements in the UW Madison CS Pool
The UW Madison CS Condor pool has been configured to check for a MemoryRequirements parameter in all Condor jobs. This parameter specifies, in megabytes, how much physical memory your job needs to run efficiently. If this parameter is not specified, Condor will assume a default value of 128 MB. Condor will only run jobs on machines with enough available physical memory to satisfy the jobs’ memory requirements. To specify this parameter, please add the following to your job description file(s): <pre> +MemoryRequirements = 90 </pre> replacing 90 with the actual memory requirements of your job in megabytes. We encourage you to continue to specify your job’s virtual memory requirements with the image_size command in your job description file.

A new paper discussing taking currently running processes and submitting them into Condor.
CondorView Client Contrib Module now available
The CondorView Client contrib module automatically generates HTML pages that publish usage statistics about your pool to the World Wide Web. Quickly and easily view how much Condor is being used, how many cycles are being delivered, and who is using them. View utilization by machine platform or by user. Interact with a Java applet to customize the visualization, or to zoom-in to a specific time frame.
More Condor Contrib Modules Released and Condor Version 6.1.1
The Condor Checkpoint server, PVM support, and CondorView server contrib modules are now online! Condor Version 6.1.1 is also available, again, for use if you know what your doing only!
Condor Contrib Modules Released
These optional modules enable you to install new parts of Condor without switching your entire pool to the development series. If you want a certain new feature (like support for SMP machines), we highly recommend you just install the contrib module for that feature, instead of upgrading your whole pool to the development series.
New Condor version number scheme
With the release of Condor Version 6.0.1, we have also introduced a new, hopefully easy to follow version numbering scheme for future versions of Condor. There will now be both a stable release series and a development release series available at any given time (much like the Linux kernel).
Condor v5.62 was available for public download.
It contains many bug patches, ports to new platforms including IRIX 6.2 and HPUX 10.20, updated man pages and installation docs, and handy extras (such as the condor_compile command).
