Campuses contributing to the capacity of the OSPool led to record breaking number of cores this December, 2022. On December 9th, the OSPool, which provides computing resources to researchers across the country, crossed the 70,000 cores line –– for the very first time.
The Center for High Throughput (CHTC) users continue to be hard at work smashing records with high throughput computational workloads. On October 20th, more than 240,000 jobs completed that day, reporting a total consumption of more than 710,000 core hours. This is equivalent to the capacity of 30,000 cores running non-stop for 24 hours.

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.
The Condor Team is pleased to announce the release of Condor 7.8.6. which contains an important security fix that was incorrectly documented as being in the 7.8.5 release. This release is otherwise identical to the 7.8.5 release. Affected users should upgrade as soon as possible. More details on the security issue can be found here. Condor binaries and source code are available from our Downloads page.
Regrettably, due to an error in building 7.6.8, it is not a valid release and has been pulled from the web. Please update to version 7.6.9 or 7.8.2 instead to address the security issue posted yesterday. More details on the security problem can be found here, and Condor binaries and source code are available from our Downloads page.

Cardiff University announces the availability of a 1,000 processor Condor Pool to the UK National Grid Service. “Use by the University’s researchers has grown considerably in this time and has saved local researchers years of time in processing their results.” “Using Gasbor to build a model of a typical Tropoelastin molecule takes 30 hours. Using Condor the same simulation ran in just two hours.”
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;
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.
After four days of presentations, tutorials, and discussion sessions, Condor Week 2007 came to a close. Red Hat presented plans to integrate Condor into Red Hat and Fedora distributions, and to provide enterprise-level support for Condor installations. Government labs reported results from their deployment efforts over the past year; for example, a production Condor installation at Brookhaven National Labs consisting of over 4800 machines ran 2.8 million jobs in the past 3 months, delivering 6.2 million wallclock hours to over 400 scientists. IBM reported on an ongoing project to bring Condor and Blue Gene technologies together, in order to enable High Throughput style computing on IBM’s popular Blue Gene supercomputer. The Condor Team reported on the scalability enhancements in the Condor 6.9 development series. Check out the 35+ presentations delivered this week.

In an interview for GRIDtoday, Brooklin Gore discusses Micron’s Condor-based grid. Gore’s comments included “We have 11 ‘pools’ (individual grids, all connected via a LAN or WAN) comprising over 11,000 processors at seven sites in four countries. We selected the Condor High Throughput Computing system because it ran on all the platforms we were interested in, met our configuration needs, was widely used and open source yet well supported.”
An article in Science Grid This Week describes how Condor combined with resources from the Open Science Grid and the Univ of Wisconsin Condor Pool provided over 215 CPU years in less than two months towards a discovery eagerly anticipated by particle physicists around the world.

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
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 NT Version 6.1.16_preview is now released, and is available on the downloads page. It fixes several bugs, including some significant memory leaks, from the previous Condor NT release. There are a significant number of changes and issues to know about between Condor NT and Condor for UNIX.
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.
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 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.
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.
The initial version of Condor NT is now available on the downloads page.
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.
Condor Downloads can now be downloaded from Bologna, Italy (courtesy of Istituto Nazionale di Fisica Nucleare Sezione di Bologna).
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.
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.
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!
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.
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).
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).
