XtremWeb 8.0.2 has been released

DEGISCO and EDGI partner Centre National de la Recherche Scientifique (CNRS) has released XtremWeb 8.0.2.

The following corrections have been introduced:

  • on the server side, the scheduling has been improved: hosts.incomingconnection is now taken into account to ensure a server like job is not sent to a volunteer resource where incoming connections are not allowed
  • on the server side, the scheduling has been improved: restoring a feature from XtremWeb 1.8.0 by INRIA: "expected host" so that the end user can specify at submission time the expected volunteer resource to run the job. Note, that if the expected host does not request a job or does not match the requirements (OS, CPU...), the job is never computed.
  • the DG to SG bridge is now compatible with shared applications so that VirtualBox on EGI resources can be used
  • some bugs corrected on client side regarding application registration and task management
  • a bug corrected on temporary file usage: they are now cleaned at software exit
  • the REST interface has been completely rewritten

New features include:

1. The creation of new Live CD can be customized

This is done by providing several optional files:

  • a text file 'user.packages' may be provided to install custom packages: this file must contain a space separated packages list
  • a text file 'user.hostname' may be provided to customize the LiveCD hostname: this file must contain the host name only
  • any package files are installed on the fly (*.rpm or *.deb, depending on the LiveCD OS)

2. The client can now be used to create SmartSockets end point, independently of any task

This may be useful to create SmartSockets tunnel from a running VM to the client PC

  • e.g. mount the client FS inside the running VM

3. A new Mac OS X package "xwhep.vworker" to deploy the middleware inside a VM

DEGISCO DEGISCO

The FP7 EDGeS project has successfully set up a production-level distributed computing infrastructure (DCI) consisting of more than 100.000 PCs from several volunteer and low-cost Desktop Grids, which have been connected to existing Service Grids (including EGEE, SEE-GRID, etc. with about 150.000 processors) based on the new 3G Bridge technology and application development methodology. The main aim of the DEGISCO project is the further extension of the European DCI infrastructure that is already interconnected by EDGeS to International Cooperation Partner Countries (ICPC) in strong collaboration with on the one hand local partners in ICPC countries and on the other hand European e-Infrastructure experts (including 3G Bridge know-how) and thus, reinforce the global relevance and impact of European distributed infrastructures. The dissemination and training activities promote via various channels such interoperation between Desktop Grid and Service Grid infrastructures on a global scale, which leads to more awareness under the general public of computational science and distributed computing co-funded by the EC. As a result more citizens, students, and companies are expected to donate resources to scientific purposes. As part of these activities the International Desktop Grid Federation is operated allowing for effective exchange of information through participation.
