Important news for Linux crunchers
We are having a problem with correctly scheduling work to Linux clients because the BOINC client for that platform does not report the Nvidia driver version to us.
If you find that you are receiving the cuda60 application version and it is not working for you, the fixes are:
*) Upgrade to driver 334.21 or later
*) Try the patched (v7.3.15) client I have made available at:
(the patch itself is at http://secure.acellera.com/insecure/boinc/gpu_nvidia.cpp_patch )
This client reports the driver version and allows a correct scheduling decision to be made.
Badges for two new papers
Dears, we have updated the badges to reflect two recent publications performed with your help:
* S. Doerr and G. De Fabritiis, On-the-fly learning and sampling of ligand binding by high-throughput molecular simulations, submitted (2013).
* P. Bisignano, S. Doerr, M. J. Harvey, A. Favia, A. Cavalli and G. De Fabritiis, Kinetic characterization of fragment binding in AmpC β-lactamase by high-throughput molecular simulations, J. Chem. Inf. Model., 2014, 54 (2), pp 362–366.
You should be able to see them in your user profile, as usual.
Recommended driver versions are 334.21 or later
As you may have noticed, we now have a CUDA 6.0 application. This brings with it several benefits over the older 4.2 and 5.5 applications, notably:
* Support for Maxwell GPUs
* Slightly improved performance
* Much lower CPU load
The minimum driver required for this app is 334.21, but any later version is OK.
In the longer term, our software development will assume CUDA 6. features, and it would be good to have as many of you as possible able to run it.
Currently 60% of all the WUs we get back are completed on machines with this driver or later (though many of you have been running the 55 app, because of our server scheduling policy)
If you have the opportunity, please do consider upgrading your driver!
Don't worry if you can't: the older applications aren't going away. From now on, though, they will get only maintenance updates.
New SR5 Mega Prime Found!
On 9 April 2014, 9:13:42 UTC, PrimeGrid’s Sierpinski/Riesel Base 5 Problem project eliminated k=104944 by finding the mega prime:
The prime is 1,125,861 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 59th overall. This is the largest known base 5 mega prime. 84 k's now remain in the Riesel Base 5 Problem.
The discovery was made by Brian Smith (Sherlock Holmes) of Germany using an Intel(R) Core(TM)2 Duo CPU T9800 @ 2.93GHz with 4GB RAM running Microsoft Windows 7 Professional. This computer took about 27 hours and 21 minutes to complete the primality test using LLR.
The prime was verified on 9 April 2014 15:47:16 UTC, by Dave Sunderland (DaveSun) of the United States using an Intel(R) Core(TM)2 Quad CPU Q9300 @ 2.50GHz with 4 GB RAM running Microsoft Windows XP Professional. This computer took about 30 hours and 46 minutes to complete the primality test using LLR.
For more details, please see the official announcement.
WU Submission SUSPENDED 19th April, 2014
In order to avoid any further errors and waste of your valuable
resources I have temporarily stopped WU submission. There are only
a few thousand WUs active and when they are cleared I hope we will have
new Windows executables. Sadly the Windows executables are now giving
wrong results in many cases. I looked at using Homogeneous Redundancy
but I would still get wrong results. I thought of removing the Windows
executables but they are over 80% of our capacity. In this way I hope in
a few days after users and support return from vacation we can safely
introduce new Windows executables after tests using the BOINC test
facility. Sorry about that but I would rather get it fixed properly as we
have lots of new work coming.
Thankyou for your patience and support. Eric.

FMA3 LLR going live on all LLR projects
Early Sunday, April 20th UTC (Saturday afternoon or evening in the western hemisphere) we are going to install the new FMA3 (aka AVX2) version of LLR on the remaining LLR projects.
Especially on Intel Haswell CPUs, but to some extent also on Ivy Bridge and Sandy Bridge CPUs, this new app is significantly faster. It also consumes more power, and generates more heat. Please make sure your computer is up to running the new app.
In general, expect the highest temperatures with shorter projects (PPSE, SGS, and PPS) while longer projects such as SoB and PSP will run slightly less hot.
Information and discussion about the new LLR app can be found in this thread.
Release of MilkyWay Sepearation Modified Fit v1.30
I have just released a new version of MilkyWay Separation Modified Fit. There were small changes made that only effected the integration area used in our likelihood calculations to be more consistent with previous versions of MilkyWay@home. This is just a minor bookkeeping change so no issues are expected, but as always if any issues come up please post them here.

Gravitational Wave search GPU App version
Due to the excellent work of our French volunteer Christophe Choquet we finally have a working OpenCL version of the Gravitational Wave search ("S6CasA") application. Thank you Christophe!
This App version is currently considered 'Beta' and being tested on Einstein@Home. To participate in the Beta test, you need to edit your Einstein@Home preferences, and set "Run beta/test application versions?" to "yes".
It is currently available for Windows (32 Bit) and Linux (64 Bit) only, and you should have a card which supports double precision FP in hardware.
Correction to the previous news post
A tiny little spelling error got into the news item from 1st of April causing it to look like BURP had been acquired by Facebook. The intended text was of course: "Happy 1st of April!"
Docking@Home is Retiring
With a heavy heart, we are announcing the retirement of the Docking@Home project. Unfortunately, we no longer have the resources to maintain the project. Starting on April 30, 2014 Docking@Home will no longer be distributing new jobs but will continue to collect results. On May 23, 2014 the server will stop accepting results as the project enters retirement. We hope that you can use this time to point your workers to new VC projects. (here is a link to active BOINC projects).
Over the past 9 years weâ€™ve had 98,512 Volunteers contribute computing power from 264,535 hosts. We have granted a total of 5,422,290,917 credits, which means our volunteers contributed roughly 159,398,584 Hours (18,196 years!) of computation. Back in Jan we made all of the result data public and we will keep that interface active. Thank you to everyone that made Docking@home a success over the years. Itâ€™s been fun! Please join us on the forums to share your best and worst story from the project.
Over the past few months weâ€™ve been working on bringing the ExSciTecH project to life. We hope that you will join us in our adventure on this new project. Feel free to stop by…

Project News Apr 2, 2014
Journal post from David BakerThere has been very exciting recent progress in designing vaccines and small molecule binding proteins using Rosetta that is described in two recent papers in Nature. These and other recent advances are described in the new Rosetta@Home Research Updates thread. It was suggested there that we send out a monthly email newsletter describing recent progress--we haven't done this before to avoid clogging everybody's inboxes but we certainly could if there is interest.
BURP has been acquired by Facebook inc.
In a short press release today the California-based company Facebook Inc. announced that they have bought the BURP rendering platform including all assets for $21 billion.
"Facebook Chairman and CEO, Mark Sugarbird" wrote:
I'm excited to announce that we've agreed to acquire BURP, the leader in BOINC-based online rendering technology using Blender.
Facebook's mission is to make the world more open and connected. This has mostly meant building mobile apps that help you share with the people you care about, but at this point we feel we're in a position where we can start focusing on what will come next to enable even more useful, entertaining and personal experiences.
BURP's mission is to enable you to experience the impossible.
Together the technologies open up the possibility of completely new kinds of experiences!
The buyout is just one in a series of large technology investments made recently, but the price tag completely dwarfs that of the Oculus Rift.
As a consequence of this merger there is going to be some changes in the near future:
- All accounts will be merged with existing Facebook accounts and will be automatically converted to use your real name and personal picture…
SETI@home/AstroPulse Beta: News
SETI@home 7.28 for ARM-Android released...
There are two versions. A version that supports NEON, and a "safe" version the just uses VFP instructions. Devices that support NEON could get either, although there should be a 3:1 preference for the neon version.
Please run whichever version you get, as cancelling results will skew the completion statistics.

POEM++ 2.0 Release
I've just updated the POEM@HOME Binaries to Version 2.00. This is the first big step for our new GPU project. I'll have to adjust some parameters of the new work units, and will send them out at the end of this week.
I'm confident the errors which occurred during the test phase have been resolved. If you encounter any problems nevertheless, please report it in our message boards.
Version 2.00 von POEM@HOME ist jetzt verfügbar. Das ist der erste große Schritt für unser neues GPU Projekt. Ich muss noch einige Parameter der neuen Workunits anpassen, und kann diese dann gegen Ende der Woche raus schicken.
Ich bin zuversichtlich, dass die Fehler, die während der Testphase aufgetreten sind, beseitigt wurden. Falls jemand dennoch auf Probleme stoßen sollte, meldet sie bitte in unserem Forum.
Status, March 2014
First, in reply to a recent query about 2014 workload, thanks to Msssimo:
"The majority of the 2014 studies will be devoted to LHC upgrade and the rest to understand the nominal
machine. I do not expect any increase in workload when approaching the LHC re-start in 2015, on the
other hand, we will all be locked up in the control room and the resources for performing the
simulations will be reduced."
Second, we have been experiencing major problems with our
Windows executables for several months now.
There are "small" result differences between Windows and Linux.
After extensive testing I believe they are due to the Windows
ifort compiler. This will be verified and fixed as soon as I
return to CERN next week. In addition new builds of SixTrack
for Windows, which now include a call boinc_unzip, are failing
on Windows in at least two ways; there is a problem parsing the
hardware description (/proc/cpuinfo on Linux) and secondly we
get "cannot Create Process" errors. So, we shall first try and
build without the hopefully resposible call, and fix the result
differences. We can then resume development of the case splitting
to smaller WUs and the return of all…

MindModeling@Home (Beta): News
Power Shutdown this Saturday (2014-03-08)
I apologize for the late notice, but I just received word that the Wright State University Engineering building where the MindModeling servers are located will be shut down temporarily this Saturday 2014-03-08 from 0700-1200 EST. I will be turning off our servers several hours in advance to facilitate a graceful shutdown. During this period, you will not be able to access our scheduler, this website, etc. There is a chance that I may not be able to remotely power-on the devices, in which case we will not have access again until the following Monday.
