- Collatz Conjecture: Variable Sized Wokunits & New CPU Applications
20.02.2014 20:32 Uhr
I have implemented BOINC’s multi-size workunits which adjusts the size of the workunit to the speed of the processor. The workunits are all named solo_collatz but there will be 4 different sizes. The smallest will be the size of that the mini_collatz workunits used to be. The largest will remain the size of the original collatz and solo_collatz workunits or 8 times the size of the smallest. There are also intermediate sizes which are 25% and 50% of the size of the largest. You can think of it as mini, small, medium, and large or 100 billion, 200 bilion, 400 billion and 800 billion numbers per workunit. That also means that even though the workinit name is solo_collatz, the credit awarded is directly proportional to the work done. The mini workunit does 1/8th the work and is awarded 1/8th the credit. The smaller size workunits allows me to release non-OpenCL versions of the CPU applications which use a single core/processor per workunit just like the old mini_collatz CPU applications. Lastly, there still seems to be an issue with multiple venues and plan class choices. A fix will be put in place as soon as I figure out why it isn’t working properly.

- Collatz Conjecture: Solo Collatz Brook+/CAL (a.k.a. ATI) Applications Released for Windows
19.02.2014 04:51 Uhr
The Brook+/CAL application, otherwise known as plan class “ATI14″, are now available for Windows and Windows 64. They are based on the 2.09 applications, but with the additional solo_collatz verification added. They utilize the same command line settings as the Collatz v2.09 ATI applications. Anyone with an AMD HD 2400 or later GPU can once again participate. In addition, those with AMD OpenCL compatible GPUs can choose via their preferences whether to run the ATI14 apps, the OpenCL AMD apps, or both. Recent AMD video drivers, especially those installed for Windows 8 and even some for Windows 7, may not install the necessary CAL DLLs and therefore cannot run the Brook+/CAL application. Try as I might to manually install them, I had to downgrade a laptop with an ATI Mobility HD 3200 GPU from Windows 8.1 to Windows 7 and also install an older version of the AMD video drivers in order to even test the solo_collatz Brook+/CAL application. Given that Brook+ has not been supported by AMD for a number of years and new AMD GPU hardware cannot run CAL applications, it is not all that surprising. So, if you have an older AMD Radeon HD series GPU that cannot run OpenCL applications and you want to continue to use it to run ATI applications with Collatz or other BOINC projects, you may want to avoid future AMD video driver upgrades.
- yoyo@home: OGR-27: Finished
18.02.2014 23:00 Uhr
After 1,821 days we finished the OGR-27 project. All stubs were computed at least twice. The Boinc part of this distributed.net project computed more than 5% of all OGR-27 stubs. At the end we had a rate of 10%. Now the Boinc server delivers OGR-28 workunits. This is to discover the most optimal Golomb Ruler with 28 marks. We anticipate that it will take about as long as OGR-27 has. It has some features in common with OGR-27: some of the packets will be very large (up to 1500 Gnodes), and there are three stub spaces. We expect that the first two stub spaces will take about 90 days to complete. For the stats freaks among you, the number of stubs for each stubspace of OGR-28 is below: Stubspace 1: 115676 Stubspace 2: 5823649 Stubspace 3: 518152118 No new application is needed, since OGR-27 clients are ready for OGR-28.

- Collatz Conjecture: Have your cake and eat it too!
18.02.2014 00:34 Uhr
While most people wanted only CUDA applications, some had some good reasons for using OpenCL applications which means it really can’t be one or the other. As a result, you can use whichever you want or even both by selecting your preferred plan class(es) for each venue. The Windows and Linux CUDA applications, both 32 and 64 bit, have been released so your preferences should take effect the next time your computer requests work. The default is that all plan classes are selected.

- Collatz Conjecture: Back Online
17.02.2014 13:51 Uhr
There was a power outage due to a fire two blocks away which brought out emergency services from four suburbs. We took several big power hits in a row. Then the UPS decided its battery was no longer any good. It gave a warning for whole seconds which wasn’t even close enough to get everything shut down properly. Everything is finally back online, just without a UPS. Considering a family just lost their entire home, I can’t really complain about losing a UPS.
- theSkyNet POGS – the PS1 Optical Galaxy Survey: New Feature, theSkyNet Challenges

Hey Guys, The current POGS challenge is flying along with SETI.USA way out in the lead. Pushing theSkyNet POGS up to a total of 62.76 TFLOPS! Amazing! I’ve finally got a prototype of theSkyNet challenge system up and running. Incorporating the feedback I received from users in December. This week and next week I’ll be trialling it alongside the 2 running and upcoming challenges on BOINC Stats. Then after that I will open it up for everyone to create and join challenges. I’m testing out too new challenge type, Peak RAC and total credit handicapped by number of users. You can see the new challenges feature at http://www.theskynet.org/challenges Main features:
- Challenges for both teams and individuals
- Challenges on a variety of stats including, Total Credit, RAC, change in leader board position and more.
- Handicap systems to give the little guys a better shot, including handicap by * RAC and number of members.
- Graphing and stats tracking of all challenges.
Planned but not yet implemented features:
- Choose which project a challenge runs on.
- More options for challenge type and handicap.
It is important that this new feature is actually useful to our members so I will appreciate any and all feedback you guys have. Cheers Alex [/list]

- Wildlife@Home: Updated new interface with skip buttons and observation comparisons
14.02.2014 21:58 Uhr
Hi Everyone, Looks like I got the skip button working on the new interface. And now when you click ‘finished’ it will display a screen showing how your observations compare to the other users (similar to the old interface). It looks like the ‘next video’ button isn’t working how it’s supposed to. I’ll be trying to fix that next. After that I’ll be working on getting an interface set up for reporting incorrectly validated videos/observations for the new interface. Since this new interface is now more closely tied to the interface Susan and her students use to watch videos (the events you enter are almost identical), I’ll have your events right up next to theirs on their screens, which should mean the reported videos should be dealt with more frequently. cheers, –Travis

- Wildlife@Home: All videos have been reconverted for the new interface
14.02.2014 19:08 Uhr
It took a few weeks, but all the 13,000+ videos have been reconverted. I’m hoping this should fix the problem with slow loading videos that some users were experiencing with browsers that used the .mp4 version of the videos in stead of the .ogv videos. These were also the videos that were sent out for work units, so that will mean they’ll take up less bandwidth (most of these videos are about 3x-5x smaller than the previous versions). cheers, –Travis
- Collatz Conjecture: CUDA vs nVidia OpenCL User Poll
14.02.2014 16:50 Uhr
Testing is finishing up on the Collatz v6.xx application for CUDA. Before I release it, I’d like your opinion on how I should configure the scheduler on the server. Should it: a) Send the CUDA if available and only send an nVidia OpenCL version if there is no CUDA version for the platform b) Send the nVidia OpenCL version if available and only send the CUDA version if there is no nVidia OpenCL version for the platform c) Let the BOINC client learn which is faster over time Note: The CUDA application uses less than 1% CPU whereas the OpenCL versions use considerably more – sometimes up to 80%.

- climateprediction.net: First meeting of new climate modelling and extreme event attribution project, EUCLEIA
13.02.2014 12:52 Uhr
Project scientists from climateprediction.net recently attended the launch meeting of EUCLEIA, a new EU-funded project which will study the attribution of weather and climate risks for Europe. The project will develop and improve the methods to help answer the important question: “How has the risk of extreme weather events changed in Europe, due to human-caused climate change?”
EUCLEIA, the “EUropean CLimate and weather Events: Interpretation and Attribution” project, will develop a climate modelling system to investigate heatwaves, cold spells, floods, droughts and storm surges in Europe.
The University of Oxford’s role will be to test different approaches to attribution, using both the Oxford Supercomputer and climateprediction.net’s distributed computing system.
Apart from the scientific development of methods and models, a large emphasis of the project is on engaging with stakeholders in local governments, businesses and media. The project will investigate the questions that people actually need answers for, and to communicate the potential and limitations of attribution science. This dissemination of the main scientific findings of the project is also led by the University of Oxford.
EUCLEIA is mainly about testing methods for attribution, so most European models run through climateprediction.net in the next few years will be related to EUCLEIA. The first one will be the standard physics HadAM3P/HadRM3P simulation for winter 2014, which should be available by the end of the month.
Other academic partners involved in EUCLEIA are:
- The Met Office, UK, which coordinates and manages EUCLEIA
- Eidgenoessische Technische Hochschule Zurich (ETH Zurich), Switzerland
- National Centre for Scientific Research (CNRS), France
- University of Edinburgh, UK
- Fundacio Institut Catala De Ciencies Del Clima (IC3), Spain
- Danmarks Meteorologiske Institut (DMI), Denmark
- Koninklijk Nederlands Meteorologisch Instituut (KNMI), Netherlands
- University of Reading, UK
- Helmholtz-Zentrum Geesthacht Zentrum Für Material- Und Küstenforschung GmbH (HZG), Germany
- Université de Versailles Saint-Quentin-en-Yvelines (UVSQ), France
The project has also made links with business collaborators including Munich Re and Zurich Insurance Group.
The project is named after Eucleia, the Greek goddess of good repute and glory.

- Constellation: 10th Google Summer of Code is on! (GSOC2014)
12.02.2014 17:12 Uhr
The application period for the 10th Google Summer of Code (GSOC2014) campaign is on! GSOC is an annual coding campaign, in which Google awards stipends (of US$5,500) to selected students who work on free and open-source software projects for certain organizations during the summer. Last year, 177 open source projects and organizations took part and mentored 1,192 students and their projects. GSOC is open for students aged 18 and older, the diverse projects range from software development for Wikipedia and Linux operating systems, to mobile platforms, to firmware and also academic work on basic algorithms, and people can mentor emerging developers during their three months of work and provide support and personal help. (some background information on Wikipedia) On a private remark about GSOC 2013, AerospaceResearch.net was lucky to have been selected as an organization and mentoring three students. This was an “awesome and motivating” experience an we advice projects and students alike to visit GSOC 2014 website and apply! Deadline is 14. February 2014 for organizations, mentor and student applications will be open afterwards! And shall we also try it again? Leave your opinion in the comment segment below! UPDATE: We received some emails and so we applied again. So let’s cross fingers! Here are our ideas.
- GPUGRID: Uncovering the role of membrane lipids in modulating enzyme activity
12.02.2014 16:19 Uhr
Hello everyone, At the end of last year, we updated the badge system to include several new publications we had just published. Today we want to highlight one of those pieces of work. Starting in Mid-2011 (an eternity ago), we began collaborating with a research group in Italy to better understand something strange they had been seeing in their experiments. Specifically, they were seeing that when they modified the composition of lipids in a cell membrane, the activity of an enzyme named FAAH increased. They came to us to try to better understand why that was happening. Through simulations performed here on GPUGRID we discovered that, contrary to expectations, the lipids modified the function of the enzyme by directly interacting with it and its endogenous ligand. It had been expected that structural changes in the membrane would be the culprit, but that was not the case. Additionally, we report the first unbiased binding of a lipid to a membrane protein. This is one of the first experiments of this kind ever performed, and was possible only because of the compute power we have here at GPUGRID. You can read more about it on the science page here, as well as check out the video of the binding event. Please note that (almost) all the papers we publish are available on our lab webpage. They can be found here. The versions of the documents there are the pre-print versions, basically meaning they are not formatted to look pretty. This is due to restrictions placed on us by the publishing companies. The text and figures are identical to those in the “pretty” version published in the journal, however. We are working on putting out copies of any papers missing from that page. Lastly, we remind you that GPUGRID accepts donations beyond compute time, and if you’re interested you can see how to do so on our Donations page. Of course, the crunching time donated by all of you is greatly appreciated. Thanks and onward, The GPUGRID Team
