  • Switch the ComputeMode domain name from ".computemode.local" to ".computemode" to not disrupt host using zeroconf

April-October 2012

  • Fix the system sshd configuration on nodes to prevent logins outside of the OAR jobs
  • Fix a few permissions in /dev (allows to run openmpi) on nodes
  • Switch to the debian packaged version of ganglia (bumps version from 3.0.7 to 3.1.7)

October-November 2011

  • The software 'Module' for the environment management is integrated to computemode (and to the node recipe)
  • Core/Cpu reservations are shown on the Drawgantt chart
  • A field 'Environment' is now available for the bootimage menu to configure a page which contains images environment description
  • A new binary for IPXE drivers network UNDI is available, this binary has an admin access to the console. A README file is available to explain how to build it from sources
  • cmwebadmin users can be authenticated with a LDAP server defined into the config.php file: when a ldap user is created into the local database, all its informations are filled with the LDAP base. LDAP users can't edit anymore their account.
  • The particpant page is available for the cmwebadmin interface, group management available: participants or administrators
  • Fix for participant rights: the participant can only configure his nodes
  • A file describing holidays planning for the participant can be used to configure nodes availability

  • Computemode system is now using an HTTP-PXE based sytem: IPXE
  • The default node has been increased to use Debian Squeeze (instead of Debian Sarge - some thing for the server)
  • OAR is now using ping checker to check aliveness of a node
  • New appliances are built for Virtualbox and VMWare based on GDM and the windows manager openbox
  • Debian Live is used to automatically build node's initrd and filesystem
  • Computemode web interface is now using the MDB2 php connector instead of the deprecated DB connector
  • Several cmwebadmin interface fixes for deprecated commands, features fixes, cmserver fixes...

April 2011

ComputeMode now based on Debian Squeeze
  • A guide to install the server on top of Debian Squeeze is available here
  • A guide to manually build a Debian Squeeze node image is available here

April 2008

ComputeMode new website is online

We decided to switch to a wiki website, to easy collaborative work.

The former website is still available here.

February 2008

ComputeMode 1.6-1 virtual appliance is released

and finally ships with the latest drivers for intel (e1000) and Broadcom (tg3) cards (sorry for forgeting about it in the previous release !)

Get it on the download page ! The web packages are available from : http://www.computemode.org/dl/computemode-1.6/

December 2007

ComputeMode 1.6 virtual appliance released

This release features all components from the former Computemode Professional version. Get it on the download page !

The web packages are available from : http://www.computemode.org/dl/computemode-1.6/

September 2007

Icatis stops supporting ComputeMode, since the company does not have resources anymore to support ComputeMode. As a result, ComputeMode will now be released as a open-source only product.

May 2007

Updated images for client nodes The current kernel image shipped with the server does not support the latest Intel (e1000) and Broadcom cards (tg3). An new image has been updated and is available at: http://www.computemode.org/dl/computemode-1.6/kernel+initrd-cm-2.4.27-3-686.tar.gz To install it (as root):

cd /var/lib/tftpboot/PXEClient
mkdir /root/bak
mv debian-initrd-2.4.27-3-686-smp debian-vmlinuz-2.4.27-3-686-smp /root/bak
tar zxvf /root/kernel+initrd-cm-2.4.27-3-686.tar.gz
chmod 0644 debian-initrd-2.4.27-3-686-smp debian-vmlinuz-2.4.27-3-686-smp

Reboot a node through PXE, and voilà ! ComputeMode 1.6 will include this update.

November 2006

ComputeMode 1.5 virtual appliance released

Get it on the download page ! The web packages are available from : http://www.computemode.org/dl/computemode-1.5/ October 2006 Several issues have been reported in the web administration interface of version 1.4.1. You can install updated web interface packages for future version 1.5. Get them from: http://www.computemode.org/dl/computemode-1.4.1/ Once downloaded, backup the /var/www/cm/config.php file, then use dpkg to update the packages. Feel free to drop by our mailing lists if you need help.

ComputeMode UFRIMA installation counts now up to 60 machines (100 in a near future) : these nodes are available for computation at night and during the week-ends, while still remaining operational for the students during the open hours. The computation power of this virtual cluster is at the disposal of the Grenoble CiGri community. An interesting point is that ComputeMode Server also allows the UFRIMA administrators to deploy the machines daytime system (Microsoft Windows and GNU/Linux Debian) automatically and efficiently (working in conjunction with Norton Ghost).

March 2005

ComputeMode is being deployed in Grenoble University

PCs of the computer classrooms at UFRIMA can now be used by the campus scientists as a powerful cluster during closed hours (at night and during holidays).

January 21st 2005

ComputeMode 1.0 is released (tagged 20050121-1935)

Year 2004

Icatis company is funded and aims at developing and supporting ComputeMode

ComputeMode is redeveloped from scratch. It now features:

  • a proper DB system instead of the home-brewed file-based version used in the Oucapo prototype
  • new initrd mechanisms with busybox, uclibc
  • the UI is heavily redesigned (from Perl cgi for 'engineers' to user-aimed PHP + templates)
  • new diskless image building tools (based on the "orig", "patch", and "rules" mechanisms)

At the same time (around April), ComputeMode v0.4 (which is still based on the Oucapo code) is released. Another proof of concept is demonstrated by integrating with a 32 nodes cluster in Total's premises in Pau, France.

Year 2003

A diskless prototype Oucapo is developed as a proof-of-concept within the ID-IMAG Laboratory. This first version (0.1) is deployed inside Total's intranet and is based on Total's customized version of Mandrake Linux 9.0. Workstations can now provide extra-computing power. The job manager used then, is Sun Grid Engine. A sismic analysis application is tested successfully and takes advantage of the power increase and reactivity provided by our prototype. The next version (0.3) is released and deployed at the Grenoble Observatory. Computing nodes are integrated in a cluster thanks to OAR.
