BOINC 7.4.42 released for Windows and Mac

News of BOINC - Mon, 07/27/2015 - 20:38

I have been running the 7.4.42 version on Yosemite (10.10.3) without issue until the past two weeks.

With Apple's latest update of 10.10.4, I have seen my boot ups hang once again on a percentage of the Late-2013 iMacs. (12 computers out of 38 in the lab).

On the older Late-2011 iMac Models running this version of BOINC, I get kernel panics which force a reboot and then once again hang before getting to the login screen. This is on 100% of the 10 iMacs in this particular lab.

I have sent these kernel crash reports, which clearly list BOINC as the offending process, to Apple and will be opening a formal bug report with them also.

If there are any logs that you would like to see, let me know and I will forward them to you.

CERN Summer Computing Challenge - beta testers please

vLHCathome news - Mon, 07/27/2015 - 14:54
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 or go to the Challenge website 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:

More information and hints.
For more detailed testing information please go to:

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.

The T4T and Challenge teams

ATLAS@home badges

Atlas news - Thu, 07/02/2015 - 04:09
We recently implemented a new badge system for ATLAS@home, and details for the ATLAS@home badge system can be found here.

For the time being, we just implemented the part to award Quark Badges our volunteers with Top RAC.

"TOP" volunteers are people who belong - for a while - to the "N % contributing most to the RAC" (Recent Average Credit). What better can we offer than... the top QUARK ?
the 90% most contributing volunteers get : DOWN quark, bronze badge
75% : UP quark, silver badge
50% : STRANGE quark, gold badge
25% : CHARM quark, ruby badge
10% : BOTTOM quark, emerald badge
the very 1% best contributors get a TOP quark, sapphire badge !

Excited about this? Check your profile and see what Quark you are now!

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:

Greetings to all from the T4T Team

Dear All,

In the next hour a new application version for all platforms will be released.

The updates in this version are:

--New vboxwrapper version.
--Changes in the vbox_job.xml

The image will remain the same as in the old version.

Your inputs are important,
Please let us know if you are having problems.

Thank you all!

New beta app (DataBridge): Tests over, please stop!

vLHCathome news - Fri, 06/19/2015 - 11:37
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.

Maintenance starting June 18, 10:30 CET

Atlas news - Wed, 06/17/2015 - 19:12
Dear all,

There will be a maintenance operation to get a separate NFS
server VM for ATLAS and Sixtrack tomorrow at 10:30 CET.

We will take care of starting and stopping BOINC. Normally this should
take less than 30 minutes (time to change a DNS alias.)

Brief Interruption, Thursday 18th June,2015

Sixtrack news - Wed, 06/17/2015 - 18:22
There will be a hopefully brief interruption to the service tomorrow
Thursday at 10:30 CST to provide separate NFS servers for SixTrack
and Atlas. The WWW pages should still be accessible and a further
message will be posted when the operation is complete. Eric and Nils.

Issues with server infrastructure

Atlas news - Thu, 06/11/2015 - 11:49
Dear volunteers,

CERN has issues with part of the infrastructure, serving the ATLAS@Home disk space. One of the file servers is unreachable, which affects the WU processing.

Sorry for the inconvenience,

Status of W boson simulation campaign

Atlas news - Mon, 06/08/2015 - 17:08
Dear volunteers,

As of today 40% of the initial campaign of W boson simulation has been completed. The first sample of the campaign contained 80.000 WUs. Thanks to the many volunteers a bit of over 7.000 Wus are concurrently processed; the total of completed WUs is a bit over 30.000.

many thanks!

About new WUs (since v1.35)

Atlas news - Wed, 06/03/2015 - 12:15
Dear all,

The new bunch of WUs released a couple of days ago with the new application are quite different than the previous ones which were submitted for some months.

Within previous WUs production of top quark within the ATLAS were simulated (you can have a look at our public web page : ). Within recent WUs, W boson decays within the ATLAS detector are simulated (we are preparing a detailed article to be posted on our public site).

As the W boson mass is 1/2 the mass of a top quark it produces much less activity in the detector through its decay. It is faster to simulate a W boson event than a top quark. As the number of events to be simulated per WU is fixed, each WU of a W boson takes less CPU cycles. That is less credit per WU for the newly released WUs.

I hope it helps volunteers understanding some the behaviours of the new bunch of WUs.

Thank you again for your help in the ATLAS simulation effort!

New application version for Windows

Atlas news - Mon, 06/01/2015 - 14:09
Dear All,

A new application version (1.36) is now available for Windows only.

The new application version is tuned to the upcoming data taking of LHC at 13 TeV collisions.
A lot of changes have been done to the software and the workunits so there might be unexpected issues with the execution. Please, let us know if you observe problems or failures of the WUs.

Thank you all!
