The Quantian Scientific Computing Environment

A Knoppix / Debian variant tailored to numerical and quantitative analysis.

Executive Summary: The most recent version is 0.7.9.2 dated 26 February 2006 and released March 1, 2006 --- the second Quantian version based on the new Knoppix 4.0.2 release. The (compressed) iso file is now 2.7 gb and corresponds to about 7.6 gb of software -- all configured and ready to be booted and used.

Support for openMosix has been backported from clusterKnoppix v3.6 with the reliable openMosix-enabled 2.4.27 kernel. The packages list ordered by size and the detailed packages list provide details about the included programs, see the changelog for a detailed summary of all the changes. Download informations are provided below. Also see the Quantian blog page, the changelog, the todo and bugs pages, and well as the set of short howtos for detailed information.

What is Quantian?

Quantian is a remastering of Knoppix, the self-configuring and directly bootable cdrom/dvd that turns any pc or laptop (provided it can boot from cdrom/dvd) into a full-featured Linux workstation. Quantian also incorporates clusterKnoppix and adds support for openMosix, including remote booting of light clients in an openMosix terminal server context. Earlier releases are still available; see below for URLs for downloads as well as ordering information.

Brief introductory information is available in a recent paper published in The Political Methodologist, slides from presentations at UseR! 2006 (June 2006), DSC 2005 (August 2005), Usenix 2004 (July 2004), and in the earlier (revised) paper about Quantian that has appeared in the DSC 2003 Proceedings.

Quantian is an extension of Knoppix and clusterKnoppix from which it takes its base system of around gigabytes of software, along with fully automatic hardware detection and configuration. To this, it add about five gigabytes of software.

What does Quantian contain?

Quantian differs from Knoppix by adding a large number of programs of interest to applied or theoretical workers in quantitative or data-driven fields. The added quantitative, numerical or scientific programs comprise

At the same time, all the distinguishing features that set Knoppix apart are retained in Quantian:

  • Auto-configuration of graphics, sound, disks, networking, auxiliary devices which is second to none among computer installations
  • A recent version (actually mostly 3.5 with some 3.4) of the KDE desktop environment
  • The GNU compiler suite comprising gcc, g77, g++ compilers including gcj
  • Perl and Python with loads of add-ons, plus other languages such ruby, tcl, Lua...
  • The Emacs and Vim editors, as well as kate, jed, joe, nedit and zile
  • Gnumeric, Koffice, ... office tools, with OpenOffice.org added back in
  • A Swiss-army knife collection of networking tools allowing access to wired and wireless lans, covering ethernet, isdn or dial-up modems
  • And still in Quantian though no longer in Knoppix: a complete teTeX TeX / LaTeX setup for scientific publishing along with wysiwyg frontends such as kile and LyX / LyX-Qt, the preview mode for emacs editors, several additonal bibtex tools, and other goodies such as prosper, pdfscreen and beamer for presentations as well as numerous Bibtex utilities.

Last but not least, and thanks to clusterKnoppix, quantian allows to build openMosix clusters in a matter of minutes -- and to immediately use them thanks to the 5 gb of added scientific software.

Screenshots

You can click on any of the images to see a full-size chart. The first screenshot shows version 0.3 with openMosix running on a cluster with two computers, an R session (run from with XEmacs using the ESS mode) with lattice graphics, the QuantLib demo 'BermudanSwaption' as well as TeXmacs -- and the Knoppix 3.2 heritage is clearly visible on the background.

The second screenshot shows Quantian version 0.4.9.3 with an openmosixview display of a three-node / four-cpu cluster as well as the kile LaTeX frontend -- and the Knoppix 3.3 background image.

The third screenshot shows Quantian 0.5.9.2 with its new custom background which was contributed by Ed Pegg, Jr. Also shown are an R session running in an XEmacs buffer controlled by ESS. The R session displays a demo from Rmetrisc which displays the sensitivities of financial options to various parameters--the so-called 'greeks'--in a 3x2 display. Also shown is openMosixview.

Mailing lists

Two mailing lists exist for Quantian, courtesy of Debian's Alioth host:
  • quantian-announce for announcements only, very low volume, posting restricted to the listowner/maintainer
  • quantian-general for general discussions about Quantian, posting restricted to subscribers -- so please subscribe before posting

Downloads

Two primary machines exist with Quantian archives: The most current version is also on Debian's Alioth site.

Note that the increased filesize may create problems with web-caching software that can only handle files of up to 2 gb in size. It may be safer to use rsync or bittorrent instead of http webdownloads.

European mirrors site are available in Madrid, Spain at RedIRIS (also with ftp access) and Aachen, Germany at RWTH (also with ftp access).

Rsync access is available at the Fred Hutchinson archive.

rsync rsync://quantian.fhcrc.org/quantian/
would retrieve a directory listing, and for example
rsync -v rsync://quantian.fhcrc.org/quantian/boot_0.6.9.x.iso . 
would (verbosely) retrieve the 0.6.9.x-compatible boot image to the current directory.

Bittorrent A new torrent is available thanks to the Linux Mirror Project, as well as at EpiGenomics (in Germany). U of Washington used to have both a bittorrent seeder and mirror with a nice graphical summary of usage, but that machine is currently, and for the foreseeable near-term future, unavailable.

Quantian for purchase

Quantian dvds and cdrom are available pre-made from the following third-party resellers: I should note that I am not compensated by any of these vendors.
