1. XtreemOS and distCooRM

2. XtreemOS Version 3 released on February 2012
Fixed many bugs in low level layers of the system
Better error reporting to the end-user
Using OpenSUSE 11.4 as a base
Updated OpenSSH, BouncyCastle, XtreemFS, ...

3. XtreemOS Work in background: Extracting API;
Extracting sequence diagram;
New code generator (without compilation circular dependencies);
Taking notes on implementation.

4. XtreemOS New version (current devel branch):
Merged an unofficial branch (decentralized service lookup, software bus profiling, software bus fixes, new monitoring services (MonDir, MonNotifMng), etc.
Job run in a login shell;
Added a job killer;
Relocated some configuration files (no automatic generation of missing configuration files);
Fixed bugs in DIXI services, fixed broken build chain (with Rémy).

5. MPI in XtreemOS Problem of XtreemOS 3 and previous:
only a modified MPICH1 supported;
complicated execution command;
xsubMPI did not honor choices made by MPI implementation.
XtreemOS devel version:
jobs are now run in a shell (esp. support for environment variables, sub-process)
command xos-createProcess plays the role of rsh/ssh, let the choice made by MPI implementations (based on supporting the standard JSDL tag CandidateHost)
Support unmodified Open MPI 1.2 and 1.4

6. ADT XtreemOS Easy Engineers: Rémy Garrigue and Mohamed-Amine Belhaj.
Work:
packaging;
installation and configuration;
virtual machines images;
open test bed (XtreemOS 3);
website;
Grid'5000 images;
deployment and configuration script (puppet);
continuous integration.
Until end of October 2012.

7. XtreemOS ANR Cloud in the EIT ICT Lab: Sajith Kalathingal, engineer.
Objective:
extend XtreemOS with machines from the cloud when needed.
Until end of September 2012.

8. distCooRM Decentralizing CooRM:
resource agendas are distributed over the resources themselves;
avoid performance bottleneck;
avoid single point of failure;
closer to the reservation management in XtreemOS.

11. XtreemOS as distCooRM Work remaining:
Internal timestamp instead of user's one;
Reservation and job refinements (new in API);
Solve conflicts with timestamp (esp. invalidate reservation with lowest priority);
3-Phase Commit (3PC);
ReservationManager on XATIBus?;
Add Vivaldi coordinates based on Ganglia;
Multiple instances of the same global services;
Multi-site execution;
...

12. Perspectives Continuing distCooRM implementation in XtreemOS:
to get experimental results for the distCooRM article;
Try new Salome on new XtreemOS.
