CERN Computing Challenge successfully completed Nové okno
The CERN 60th anniversary 12 day "Public Computing Challenge" has just successfully finished. Please see https://test4theory.cern.ch/challenge/ for all the details, and many thanks to all of you who contributed.

As you know, completed Challenge jobs help to fill a database to support a new interactive "game" project we are developing, whose users will be able to tune the Monte Carlo QCD models at the heart of Test4Theory.
Even though the official 12-day Challenge is now over, you can still continue to contribute to this database by running WebAPI jobs logged in with Facebook, Google or Twitter accounts, or even anonymously.

Note that if you are logged in to WebAPI with your BOINC-T4T account, you will run jobs from the BOINC vLHCathome job stream, and receive MCPlots statistics for them.

We send holiday and New Year greetings to all our T4T volunteers and look forward to sharing some exciting developments with you next year.

New Nbody version 1.46 Nové okno
Hey Everyone,

There is now a new version of Nbody, 1.46. This version calculates the initial Dwarf galaxy using a different method than previously. It should solve many of the work unit stalling issues some users were having. If there are any errors let us know.

The runs currently up are:

New tasks have been released Nové okno
Dear all,

The migration of ATLAS production system is almost complete, for a week now test tasks have been submitted with success.

We are currently resuming normal production rate with task of almost equal duration length.

We have noticed an increase of ~20% of the activity on the ATLAS@home project and would like to warmly thank all the volunteers for their contribution.

After Xmas we shall release a new version of software that includes a new version of vboxwrapper.

Best regards

OpenMalaria v33 on beta Nové okno
Dear users, We have just updated the Beta application on malariacontrol.net to version 33 of our simulation software, OpenMalaria. At the same time we have started some new jobs to take advantage of the features in this version of the software. Since several users reported problems with the 64-bit Windows version of the app added in the last Beta update, this has been disabled and we have reverted to using the 32-bit version on 64-bit Windows. - Malariacontrol.net team

New Nbody Nové okno
Hey Everyone,

We will be releasing a new Nbody application this week. This version of the application utilizes a different method of initializing the bodies, sampling a distribution function instead of a potential. This version will hopefully resolve issues many of you have been having.

Happy holiday season Nové okno
Hopefully, a lot more GPUs and CPUs will join after the holiday presents. At GPUGRID we are going away starting next week. The first to come back is Nate by the end of the year, early new year. Also still remember that if you want, there is the possibility to make a donation. Donations are used to fund a PhD student which can work on Gpugrid. Last year we have received many donations. Thanks to everybody. This year we also did well in terms of scientific publications: N. Stanley, S. Esteban and G. De Fabritiis, Kinetic modulation of a disordered protein domain by phosphorylation, Nat. Commun. 5, 5272 (2014). pdf G. Lauro, N. Ferruz, S. Fulle, M. J. Harvey, P. W. Finn, and G.

Most of the Campaign #9 applications are online with work Nové okno
Most of the Campaign #9 applications are online with work.

The campaign #9 is for mining 10,000 USD worth of cryptocurrencies for the exciting work of Dr. James Woodward. They want to raise 42,000 USD in total for the Woodward Lab at CalState Fullerton to get new instrumentation, computers and power supplies to continue the research on Mach Effect propulsion.

Server moving and scheduled outages Nové okno
Server is going to be moved on 17.12.2014. It will be offline since 11:00 UTC, it will be online probably the other day. Another circumstance requires server to be offline every day between 19:00 - 09:00 UTC till January. I will write another info if anything change. I also write more information at forum about it.

I have switched the pool for C-cpuminer WUs to ipominer.com. It is still using the same old cpuminer app and it is still mining Scrypt (Viacoin (VIA)).

cpuminer_9 in beta test Nové okno
If you want to run cpuminer_9 application at the moment, you need to enable test applications in your project settings.

What is new?
- ipominer.com pool (instead of multipool.us)
- Neoscrypt CPU mining (instead of Scrypt CPU mining)
- The WUs should run 30 minutes and after that the time limit is reached, and, hopefully, the WUs will validate
- Campaign #9 is making money for the Woodward Effect experiments

Recent problems Nové okno
Hi there, recently, we experienced some unfortunate problems: 1. The server hardware is old and can barely deal with the increasing load. This frequently leads to an unresponsive server. Website visitors are mainly affected since the boinc clients deal with the problem by trying to reconnect later on. The reconnects increase the problem additionally. 2. After getting back from two weeks of vacation, I realized that parts of the dDM database crashed and had to be restored. As far as I can see, we suffered no loss of important data. Maybe, some changes of user profiles were not stored. 3. The amount of dDM data increases steadily and the corresponding backup takes much more time than in the early stages of the project. As a result, the announced maintenance periods are no longer sufficient. I will think about a new backup strategy. 4. Some users reported about validation problems. I guess, this was due to the issues mentioned above. Right now, the validation of WUs is almost finished. I apologize for any inconvenience caused by these problems. Cheers, Nico

New Modfit Runs Nové okno
Hey Everyone,

Just a heads up, I will be starting new runs over the next couple days that will have a different step size in a computationally intensive section of our code. Through some work we did, we found that this step size could be optimized and reduced to improve the speed at which our code runs without sacrificing accuracy. We expect to see these runs complete in about 1/5th the time depending on the platform. Credits will hopefully still be calculated correctly, but if you think they are not for these runs please post here. If these runs cause you any trouble with these runs or you notice you stop receiving work units please post that here too. These runs will all include the tag _fast_ in the work unit name so it should be easy to track.

For now, these optimizations will only be used on the Modfit code, but in the near future we plan on also using them on original separation code, too.

If you have any questions about this optimization or problems, please let me know,

321 Mega Prime! Nové okno
On 22 November 2014, 14:46:02 UTC, PrimeGrid’s 321 Prime Search project found the mega prime: 3*2^11484018-1 The prime is 3,457,035 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 12th overall. This is the largest known 321 mega prime and the largest prime found to date at PrimeGrid! The discovery was made by Serhiy Gushchak (Sergyg) of the Ukraine using an Intel(R) Core(TM) i3-2120 CPU @ 3.30GHz with 12 GB RAM running Microsoft Windows 7 Ultimate. This computer took about 27 hours and 2 minutes to complete the primality test using LLR. Serhiy is a member of the Ukraine Team. The prime was verified on 24 November 2014 11:24:03 UTC, by Thomas Schulze Curly of Germany using an Intel(R) Core(TM) i7-3770K CPU @ 3.50GHz with 16 GB RAM running Microsoft Windows 7 Professional. This computer took about 32 hours and 56 minutes to complete the primality test using LLR. Thomas is a member of the BOINCStats Team. For more details, please see the official announcement.
