- PrimeGrid: New SR5 Mega Prime Found!
19.04.2014 18:40 Uhr
On 9 April 2014, 9:13:42 UTC, PrimeGrid’s Sierpinski/Riesel Base 5 Problem project eliminated k=330286 by finding the mega prime: 104944*5^1610735-1 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.
- SIXTRACK: WU Submission SUSPENDED 19th April, 2014
19.04.2014 11:05 Uhr
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.

19.04.2014 10:50 Uhr
I will continue checking in weekly….
I concur with Aurel and Ex-Brit.
The last update was over a month ago. I keep checking back regularly, almost daily, in eager anticipation of more WU’s.
Ant, can you please try to give at least a ball-park estimate when this project will be back and running again?
- YAFU: Problems with yafu server
19.04.2014 07:05 Uhr
the yafu server runs in a virtual box (4.3.10) VM on my 64 bit Win 7 Laptop. Round about 6h after the VM was started I get an BLKCACHE_IOERR from virtualbox which usual means that the disk is full. But it’s not. The host has 40GB free disk and the guest is also only 20% filled.
I did some changes on the system and don’t know if it fixes the issue.
I’m abroad the next days. So it might be that the server stops working again until I’m back.
- PrimeGrid: FMA3 LLR going live on all LLR projects
18.04.2014 22:08 Uhr
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.
- MilkyWay@Home: Release of MilkyWay Sepearation Modified Fit v1.30
15.04.2014 16:45 Uhr
Hi everyone, 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. Thank you, Jake W.

- Einstein@Home: Gravitational Wave search GPU App version
11.04.2014 09:12 Uhr
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. BM
- climateprediction.net: Latest update on results from weather@home 2014 UK Flooding experiment
10.04.2014 15:59 Uhr
Here is the latest plot for the weather@home 2014 UK flooding experiment:
We have now analysed over 33 thousand models!
The curves are quite hard to tell apart, so we’ve zoomed in on an interesting part of the plot so you can see the blue and green curves separately.
The further apart they are, the more climate change increased the risk of last winter’s flooding event.
However, we still have to wait for more models to come back and do more analysis before we can say if this change is statistically significant.

- PrimeGrid: Badge threshold changes
09.04.2014 12:11 Uhr
For longer than I can remember, some of PrimeGrid’s badges have required twice the credit as other badges. The reason for that difference long ago ceased to be relevant and so we have lowered the required credit for those badges to be the same as all the others. Therefore, you may have gone up a badge level in those projects. This change also applies retroactively to closed or suspended projects. The affected projects are all the sieves, AP26, GFN, and PSA. Discussion of this topic is in this thread.

- Docking@Home: Docking@Home is Retiring
07.04.2014 22:05 Uhr
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 we’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. It’s been fun! Please join us on the forums to share your best and worst story from the project. Over the past few months we’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 the ExSciTecH forums and say “Hi”!. Thanks for your support over the years! The Docking@Home Team

07.04.2014 16:10 Uhr
Hey everyone, I am sending out some WUs to the long queue called BARNA (pun intended). The system we are investigating is Barnase/Barstar which are two proteins that interact with each other. http://en.wikipedia.org/wiki/Barnase http://en.wikipedia.org/wiki/Barstar This will be (as far as I know) our first protein-protein interaction study and we are hoping to study some interactions like the ones in the crystallographic model and further develop the corresponding analysis tools.
- Wildlife@Home: speed options for watching videos
06.04.2014 23:25 Uhr
So I did a little testing and it looks like (at least on OSX) Safari and Chrome support speeds from -16 to +16; and the watch page allows that. Firefox on the other hand only seems to allow speeds between 1 and 5, so it’s somewhat limited. Is anyone else seeing something similar on other operating systems?
- Wildlife@Home: reporting observations is now working
06.04.2014 21:06 Uhr
Hi Everyone, I’ve pushed some more recent changes to the website. It’s not possible to report observations in the review videos page, http://volunteer.cs.und.edu/wildlife/review_videos.php, or alternately click on your name in the top navbar then on review videos. This should be used if the validator flagged observations as invalid when it should not have, or vice versa. That way one of our scientists can go in and set the validation status manually (and give a response as to why it was done). Now that this is working for the new interface, I have two priorities to work on: 1. fix the speed/rewind buttons in firefox (and chrome?) 2. get the new validator working properly and up and running 24/7. cheers, –Travis
- Collatz Conjecture: Tip #42: User of the Day
06.04.2014 15:02 Uhr
How can you become the user of the day at your favorite BOINC project? Create or edit your profile. You won’t be chosen as user of the day on a BOINC project unless you have a profile. Once selected, you won’t be selected again unless you make some type of change to your profile. “There are 9 remaining candidates for User of the Day.” That’s what the Collatz server is currently telling me. If the BOINC project admin knows a little SQL, he can reset the flag for the user of the day manually, but most won’t ever both doing that. So, editing your profile or creating one if you don’t have one is the best way to get your name back on the list. In addition to showing your profile on the project home page when you are chosen as “user of the day”, there is a site dedicated to tracking it over time much like the BOINC statistics sites track credits. Check it out at http://uotd.org
- GPUGRID: New CPU work units: 3HHM-1/ZINC
06.04.2014 10:38 Uhr
Hi gang, The testing for the CPU application is over and these are the first production WUs. In this project we are studying the PI3Kalpha, a mutation of which is implicated in tumor formation. You can read more about it, and see the structure, here: http://www.rcsb.org/pdb/explore.do?structureId=3HHM Over the course of this project we will be testing some 22 million commercially-available drug-like molecules, drawn from the ZINC database http://zinc.docking.org/, to find compounds which are predicted to bind strongly to the protein in a way which will inhibit its function. Once we have screen the whole database, we will take the best hits and test them for efficacy in a series of in vitro experiments. Hopefully we will find inhibitory compounds which can then serve as the basis for future drug development. Matt
