XtreemOS Summer School



Wadham College, University of Oxford

Oxford, UK, September 7-11, 2009 


Wadham College 



XtreemOS is a Linux-based operating systems that includes Grid functionalities. It is characterised by properties such as transparency, hiding the complexity of in the underlying distributed infrastructure; scalability, supporting hundreds of thousands of nodes and millions of users; and dependability, providing reliability, highly availability and security.
The XtreemOS Summer School will include lectures on modern distributed paradigms such as Grid computing, Cloud computing, and network-centric operating systems. The Summer School will combine lectures from research leaders shaping the future of distributed systems and world leaders in deploying and exploiting distributed infrastructures. Hands-on laboratory exercises and practical sessions using XtreemOS will give participants experience on using modern distributed systems.



The aims of the XtreemOS Summer School are:

  • To introduce participants to emergent computing paradigms such as Grid computing and Cloud computing
  • To provide lectures and practical courses on novel techniques to achieve scalability, highly availability and security in distributed systems
  • To present Grid applications in the domains of E-science and business.
  • To provide a forum for participants to discuss your research work and share experience with experience researchers.

Practical Information


Students and post-docs, as well as scientist, interested to attend the XtreemOS Summer School 2009 are kindly invited to fill out the registration form that is available below. Alternatively, an application form can be requested (and submitted) by e-mail at The deadline for registration is July 26th, 2009 * extended to August 5th, 2009 * -- Registration is now over.

The fee for the school is 275 British Pounds (GBP). It includes accommodation in standard single room, breakfast, lunch (from Tuesday 8th), and participation in social activities (Welcome reception on Tuesday 8th, and Social Dinner on Thursday 10th).  *** The deadline to request grant is now over: we will not be able consider any additional grant request *** A small number of grants are available which will be awarded to candidates whose financial circumstances might otherwise prevent them from attending the school. The grants can only be used for a (partial or full) waiver of the fee. Requests for support need to be accompanied by one letter of support written by a senior scientist (preferably your University supervisor). All material needs to be sent by email to  

The participants are expected to plan their arrival on the Monday morning, September 7th, 2009, and their departure on Friday afternoon, September 11th, 2009. Lunch on Monday will be provided at 13:00 GMT.
