What is OSCAR ?

OSCAR allows users, regardless of their experience level with a *nix environment, to install a Beowulf type high performance computing cluster. It also contains everything needed to administer and program this type of HPC cluster. OSCAR's flexible package management system has a rich set of pre-packaged applications and utilities which means you can get up and running without laboriously installing and configuring complex cluster administration and communication packages. It also lets administrators create customized packages for any kind of distributed application or utility, and to distribute those packages from an online package repository, either on or off site.

OSCAR installs on top of a standard installation of a supported Linux distribution. It installs and configures all required software for the selected packages according to user input. Then it creates customized disk images which are used to provision the computational nodes in the cluster with all the client software and administrative tools needed for immediate use. OSCAR also includes a robust and extensible testing architecture, ensuring that the cluster setup you have chosen is ready for production.

The default OSCAR setup is generally used for scientific computing using a message passing interface (MPI) implementation, several of which are included in the default OSCAR package set. One of OSCAR's strengths is that it is possible to install multiple MPI implementations on one cluster and switch easily between them, either at the system default level or the individual user level.

Other types of applications which use clusters of computers, such as load balancing web clusters and high availability clustering packages, would certainly be fairly easy to implement using the OSCAR package system but are outside the expertise of our current development team.

Anyone is welcome to contribute to OSCAR core development, or to submit packages to be included in the default OSCAR repositories. We are a community driven project and are always on the lookout for new talent and ideas.

Monthly Chairman Bulletin - November 2008

We have a good news this month: an new alpha version of OSCAR-5.2, the second one, is available (note that this is still a snapshot of trunk). This version supports both Debian based systems (i.e., Debian 4.0, ubuntu-7.10, and ubuntu 8.04) and RPM based system (i.e., CentOS-5 i386, CentOS-5 x86_64, RHEL-5 i386, and RHEL-5 x86_64)!

From now, we just need to test this version to be able to release OSCAR-5.2. Also note that this version only includes OSCAR core, OSCAR packages will be incl ...

OSCAR BoF at SuperComputing 2008

We organize this year again a Birds-of-Feather (BoF) at SuperComputing 2008. Please join us if you plan to attend SuperComputing. We will do some announcements during the BoF. :-)

Monthly Chairman Bulletin - October 2008

We have a good news this month: an alpha version of OSCAR-5.2 (in fact the SVN trunk) is available for Debian based systems (i.e., Debian 4.0, ubuntu-7.10, and ubuntu 8.04)!

The major modifications for OSCAR-5.2 are:

  • support of online repositories (no need to create local repositories if your cluster headnode has access to internet),
  • the apparition of a new OSCAR component: the OSCAR Repository Manager (ORM), which provides an abstraction for the management of OSCAR repositories ...

Monthly Chairman Bulletin - September 2008

This month i would like to point at the latest developments on the OSCAR core:

  • OSCAR Repository Manager, a.k.a. ORM, has appeared. ORM is a simple abstraction on top of PackMan? that allows one to easily deal with a given Linux distribution: when creating a new ORM object, one can specify the Linux distribution the object is associated with, and then ORM knows which OSCAR repositories must be used, how to bootstrap an image, and how to manage binary pack ...

Monthly Chairman Bulletin - August 2008

We had many summer projects this year:

  • NFS Mountpoints in OSCAR, by Paul Greidanus. OSCAR currently does not have an option to allow non-"standard" NFS mount points, this project would be to extend OSCAR's native NFS mount points, to include all mounted NFS servers on the head node, and clone that configuration onto the node image. Also, investigate automounters, and cloning automount configuration as well.
  • Implementation and Integration of a Universal Monitoring Framework ...

Monthly Chairman Bulletin - July 2008

System-level virtualization is today widely used for server consolidation and even if the benefits of system-level virtualization for High Performance Computing is still very unclear, one may argue that a management software such as OSCAR should support virtualization. What is the current support for virtualization in OSCAR? Is it possible to deploy VMWare or Xen virtual machines with OSCAR and to monitor them remotely? A team at ORNL was actually working on that issue and the OSCAR-V project ...

Monthly Chairman Bulletin - June 2008

First of all, let me introduce myself. I am Geoffroy Vallee, scientist at the Oak Ridge National Laboratory and chairman of the OSCAR project since few weeks. As chairman, i will try to publish a "bulletin", each month, highlyting few interesting points. It can be ongoing developments, current unknown features or even related projects.

This month, i will present a specific point i would like to focus on for the next OSCAR releases: the isolation of a small and simple core, and the separation ...
