Test4Theory

This is a project that utilizes the CERN-developed CernVM virtual machine and the BOINC virtualization layer to harness volunteer cloud computing power for full-fledged LHC event physics simulation on volunteer computers.

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.

Please visit the LHC@home web site for more documentation, data and instructions. If you have any problem, question or doubt please visit the Message Board, Questions and Answers and FAQ sections of the project.

Server maintenance 12 UTC
The BOINC server will be down for maintenance for about 1/2 hour from 12:00 UTC today.

Like usual, BOINC clients will back off and upload results later once the server is available again.

Many thanks for your contributions to LHC@home!

Citizen Cyberlab Survey (with prizes!)
Colleagues from the Citizen Cyberlab project http://citizencyberlab.eu are studying how citizen science projects can be designed to help you learn more about the scientific topics concerned, and making participation more interesting and useful for you.

They propose a 15 minute survey at https://tecfalabs.unige.ch/survey/index.php/372819/lang-en (or at https://tecfalabs.unige.ch/survey/index.php/372819/lang-fr in French).

First prize is either a 500€ gift voucher for amazon.com or free participation and travel subsidies for the Citizen Cyberlab Summit this coming autumn: http://www.citizencyberscience.net/2015/05/announcing-the-citizen-cyberlab-summit-geneva-17-18-september-2015/. 20 other participants will receive a 32 GB USB-3 key.

Closing date is September 1st, so hurry up and take the survey now!

Vboxwrapper upgraded
vboxwrapper 26169 has been deployed for all architectures.

(We have not yet deprecated the older app versions, will do so when the new one is confirmed to be ok).

This version should support VirtualBox 5.x

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.
