The Linux Symposium was held at Montreal, Canada, from July 13th to July 17th.

John Mehnert-Spahn (UDUS) gave a technical presentation of 45 minutes on his work "Incremental Checkpointing for Grids" on July 15th. John explained the motivation behind incremental checkpoint and its implementation in Linux SSI as well as its integration in XtreemOS. There was much interest in the implementation of incremental checkpoint. 

On 17th July Surbhi Chitre (INRIA) held a BOFs session for XtreemOS. She explained why XtreemOS is attractive and how it is a complete solution for grids. She also explained her work of integrating OpenVZ in XtreemOS, why it was chosen and the challenges in doing so. In her talk, she also gave a brief introduction to XtreemFS features. This was followed by a presentation by Louis Rilling of Kerlabs of Kerrighed Clusters which is supported by XtreemOS.
