\"Condor\" name changing to \"HTCondor\"

October 25, 2012

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

July 12, 2007

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

July 5, 2007

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.

Fortran bugs found in version 6.1.11 for Solaris and IRIX

February 1, 2000

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_status bug in 6.1.10 found

November 1, 1999

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

November 1, 1999

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.

Use of MemoryRequirements in the UW Madison CS Pool

March 1, 1999

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.
