  • theSkyNet POGS – the PS1 Optical Galaxy Survey: Pause in Galaxies

    The team-join failures seem to be unrelated but there does appear to be an issue with the way BOINC is handling SSL certs that we are investigating.

  • PrimeGrid: Genefer 3.2.2 released
    27.07.2014 21:59 Uhr
    The latest version of Genefer, v. 3.2.2, has been released and is live for both short and World Record tasks. Some notable changes: 1) The OpenCl and CPU apps are significantly faster than the previous versions. 2) It is likely that the OpenCL app is now faster than the CUDA app on any Nvidia GPU, but especially on newer (Kepler or later, 6xx or newer) GPUs. On the app selection page, the OpenCL app now appears before the CUDA app. NOTE: On Nvidia cards, the OpenCL driver hogs a CPU core. If you have an Nvidia GPU, you may chose between the faster app (OpenCL) or that app that uses very little CPU (CUDA). 3) The CPU app now supports the FMA3 instructions on Intel Haswell CPUs, which makes them even faster. 4) The bug in the Mac ATI app has been fixed. Please see this thread for more information and discussion.

  • SIXTRACK: Power Supply Ripple
    22.07.2014 15:40 Uhr
    Asequesed and for your information Miriam has described her recent studies as follows: A principal component of the planned upgrade to a high luminosity LHC (HI-LHC) is the replacement of the high field quadropole magnets – the so called “inner triplet”. The long term beam stability can be significantly reduced by magnetic field errors, miasalignment of the magnets and by irregularities in the power supply (ripple). The recent batch of fifteen or so studies, involving over one and a half million cases or Work Units each of one million turns (for a stable beam), are aimed at determining the maximum allowable tolerances for the power supply ripple assuming the known field and alignment errors.

  • GPUGRID: New CPU Application for testing
    21.07.2014 21:07 Uhr
    Hi, There’s a new CPU app available for Linux clients. A few WUs are out now, with some more to come after I’ve received the first results back. The app is multithreaded, I think the default behaviour of the BOINC client is to allocate all cores to it. Please report any observations here. Matt

  • MilkyWay@Home: Milkyway/Bitcoin Utopia Update
    19.07.2014 21:33 Uhr
    Friends…. Another Boinc project has come aboard to help us fundraise for Milkyway. Bitcoin Utopia has agreed to team up with us on fundraising for Milkyway’s future. To take part in this type of assistance for our project, please go to their site and follow their procedures. Their program for Milkyway is Campaign #3. We truly appreciate their support! Disclaimer: The Milkyway project staff, students and moderators are not responsible for any issues your computer may have with their WU’s. Please follow their recommendations for optimal results (credits are pretty nice too!). Any concerns or questions over how their project raises funds should be posted on their website for their admins to assist. The Admins of Bitcoin Utopia are fantastic people and my experience shows they will do whatever they can to assist you. Also remember Bitcoin Mining is not a quick process so the Bitcoin Utopia folks and us want to remind you to still donate in the more direct manner if you wish to. Any support is appreciated tremendously!

  • Updating test application
    18.07.2014 09:02 Uhr
    Dear users, As of today, I am updating the malaria control test application to OpenMalaria v32 (see previous news item). Also today, I will be starting a small experiment using this simulator version of roughly 17000 workunits. With this release comes support for an extra platform: 64-bit Windows (previously, the 32-bit Windows application was used on both 32-bit and 64-bit Windows). This build requires the .NET framework and has so far only been tested on Windows 7 and 8.1, so let us know if you run into any issues. - D Hardy
  • PrimeGrid: Mega Prime Search Now Running on BOINC
    18.07.2014 01:37 Uhr
    We have moved the PRPNet MEGA project over to the BOINC server. To run PPS-Mega, just select the PPS-Mega (LLR) app in your PrimeGrid Preferences. The PPS-Mega project is part of our Proth Prime Search (PPS) project. There’s now three ranges of PPS tests: PPSE: Currently around n=1.3M and about 400K digits PPS: Currently around n=2.1M and about 650K digits Mega: 3.322M < n < 3.6M and just over 1 million digits The PPS-Mega tasks take about an hour on the fastest computers (Intel Haswell CPUs). This project is ideal for finding mega primes. In all of history, only 97 mega primes have ever been found -- but PrrimeGrid has already found 17 so far this year. Will you discover the next mega prime?

  • MilkyWay@Home: MilkyWay@home passes 50% of fundraising goal!!
    15.07.2014 20:40 Uhr
    Hello Everyone, I would like to let you all know we have surpassed the 50% mark for our fundraising goal! We could not have done it without you all, Thank you! here is a message from Professor Newberg: “I would like to personally thank each and every MilkyWay@home supporter who has helped us to raise $21,843.97 towards our goal of $40,480 to keep up operations through summer 2015. So far, 324 people have sent money by credit card, Paypal, and check to support our work of tracing tidal streams in the Milky Way halo and using them to determine the location of dark matter. We have received donations from $0.23 to $5000 (Wow!), and sent out 36 fabulous T-shirts to donors. Some of you have included really wonderful notes along with your donations, that I have really appreciated. Already, your donations have made it possible to offer Jake Weiss his co-op job for fall 2014, we know we will be able to continue to publish our papers in highly cited journals for the next year, and graduate student Sidd Shelton has his summer salary funded. This puts in a much, much better position than we were two weeks ago. Additional donations will fund conference travel (so we can tell other scientists about our findings, and get new ideas) and undergraduate student summer salary. Undergraduate research have in recent years been the driver behind MilkyWay@home software development, but to continue that they need summer support and opportunities for professional travel. Thank you all, really, for your continued support of MilkyWay@home. Sincerely, Prof. Heidi Jo Newberg” Cheers, -Sidd
