The theory simulations that have been running as Test4Theory since 2011, were the first of a series of physics applications running on the LHC@home platform. Soon the theory simulations will be followed by more simulations from the LHC experiment collaborations. These applications exploit virtual machine technology, enabling volunteers to contribute to the huge computational task of searching for new fundamental particles and physics at CERN's LHC.

Job offer: Studentship to work on WebAPI technology
The MCnet organization (http://www.montecarlonet.org) is offering a 3 month studentship to work on developing the CernVM_WebAPI technology currently being tested in the CERN Summer Computing Challenge. Anyone registered for a PhD in experimental or theoretical particle physics may apply.

CERN Summer Computing Challenge - beta testers please
Late last year we ran the first CERN Public Computing Challenge to test several new technologies for volunteer computing. Now we are preparing the Summer 2015 edition. We've made many improvements so it needs some final testing and we believe that the T4T community is ideal for this. To help us, just point a Web browser to the URL http://test4theory.cern.ch/vlhc or go to the Challenge website http://test4theory.cern.ch/challenge and click "JOIN NOW" and "START COMPUTING".
What's new this Summer?
The new VM has several advanced features:
(1) It uses micro-CernVM which boots faster than CernVM, and it uses the new DataBridge to get jobs faster than CoPilot.
(2) it runs up to 4 simultaneous jobs. If you offer n <= 4 CPU's it opens n Linux containers and runs them all inside your single VM.
(3) It supports jobs coming from multiple projects, not just Test4Theory jobs, so there's an entirely new credit system included called "Credit-Piggy" which collects your credits from all projects into your personal piggy-bank.
To begin with we will be running standard jobs from the Test4Theory project with all results going to the MCPlots database. If you click on the small "BOINC" button at the bottom of the WebAPI page and set your BOINC T4T user ID, then in addition to your Piggy credits you will also collect MCPlots stats for your Billionaire's Club, etc.
Also note: the old Challenge VM was a copy of the current Test4Theory 32 bit CernVM image. The new one is 64bits which means you MUST have VT-x or AMD-V enabled! For help on this see: http://www.cern.ch/ben/64bit-VTX.html
More information and hints.
For more detailed testing information please go to: http://www.cern.ch/ben/Challenge-webapi-hints.html
Please give your feedback initially on this Message Board thread.
Thanks to everyone for supporting T4T and looking forward to your help and interest for our future developments.

2 TRILLION EVENTS REACHED BY TEST4THEORY TODAY !!!
Congratulations and thanks to all our volunteers for helping CERN to reach the extremely impressive total of 2 Trillion events successfully simulated on our project.
When we passed our 1st trillion events in 2013, CERN published the following story on its Web site, and it still makes excellent reading:

New beta app (DataBridge): Tests over, please stop!
Thanks to all who tested the new DataBridge system. Tests are now completed and we have no more MCPlots jobs in the DataBridge queue, so remaining beta app tasks will run idle VM's which is wasteful.
*** PLEASE ABORT ANY RUNNING BETA APP TASKS AND TURN OFF THE BETA APP FLAG IN PREFERENCES ***

New beta app: Theory simulations using DataBridge
A new version of the Theory simulations application is now available for users that allow test applications. The simulations running in the VM are similar to those in the regular Theory application, however the queue and job management to the VM is handled via the "Data Bridge" application layer that is a new and more flexible framework that is intended to replace the CoPilot application layer that has been used up to now.
Happy crunching! 7 May 2015, 12:44:58 UTC · Comment
