  • Collatz Conjecture: Brook/CAL ATI for 32-bit Linux
    14.03.2014 21:00 Uhr
    I added a 6.00 version for 32-bit Linux app w/ ATI Brook+/CAL SDK 1.4. It compiles, but I have no idea whether it actually works as it was built on an Ubuntu 12.04 machine. That build machine does not have an AMD GPU installed which mean getting a little creative in order to get the Brook/CAL libraries installed. If it will not run on your machine at all, please run “ldd solo_collatz_6.00_i686-pc-linux-gnu__ati14″ and post the output. If it runs but errors out, please post the stderr.txt (the normal BOINC output). If it does run, let me know as well. It uses the same command line parameters as the v2.09 ATI apps.

  • Constellation: Comet Trails: An IMEX application for predicting meteor storms at spacecraft or planets
    12.03.2014 15:11 Uhr is happy to announce the next application running on the Constellation platform, the “IMEX Cometary trails”. After successful tests during the last months, you will now help predicting meteor storms at spacecraft or planets by donating idle computing time. Description: The “IMEX Comet trails” project is an ESA-funded project run at the Institute of Space Systems (IRS) at the University of Stuttgart to characterize dust trails produced by comets in the inner solar system. We want to predict meteor showers at any position or time in the solar system: for example, can we predict meteor storms at spacecraft or at other planets?; can we understand how dust produced by comets disperses to form the interplanetary dust cloud? mqdefault Alle BOINC Projektnews (click here for Youtube-video Motivation: Meteoroid environment modelling is crucial to providing hazard risk assessments for the design phase of spacecraft missions: meteoroid impacts can damage or destroy spacecraft or spacecraft subsystems. Manned space activities are especially vulnerable to any damage caused by meteoroid impacts because of their much lower tolerance level, their large cross sections and their long exposure times. Such models also provide an important scientific role by helping to defining the dust environment and the parent bodies of these grains. Existing dust environment models do not include small-scale and time-dependent structures caused by streams and trails of recently released cometary material. Dr. Rachel Soja (IRS) commented: “I can’t wait to see what this plot looks like with all of the data! This data is intended for our first analysis of Leonid meteoroids on the date of one of the best Leonid storm in my lifetime – 18 November 1999. If they hit Earth in our model, then our model is ok. We’ll know this when we have all the data.13106221343 72e439341c n Alle BOINC Projektnews comet_trails_jupiter by on Flickr The IMEX contribution: The Interplanetary Meteoroid Environment for eXploration (IMEX) project aims to close this gap, allowing for identification of the important cometary streams at any point in space and time. We extend the application of meteoroid stream modelling at the Earth to ask whether we can determine `meteor showers’ that occur at spacecraft locations or at other planets or points of interest. This improves both our understanding of the impact hazard to spacecraft, and our understanding of the formation and dispersion of cometary trails and streams. Integrating dust trajectories with Constellation: We have developed a simple model of emission of dust from comets. We now need to integrate the trajectories of these dust particles as they orbit the sun, in order to explicitly include the effect of planetary gravity (Jupiter is a major perturber). For each comet we have thousands of test particles which must be integrated for 200-400 years. This problem is therefore trivially parallelizable. Our first aim is to model meteor storms and outbursts at the Earth to validate the model for use in predicting the meteoroid environment at other locations in the inner Solar System. First Work-Units: Our first workunits are to compute streams for the Leonids and the October Draconids. These are two meteor showers that we observe each year at the Earth – Leonids in November and Draconids in October. However, in some years, we pass through a trail of very recently released dust and rocks, and we see a ‘meteor storm’. The Leonids storms have been the most spectacular displays of meteors ever witnessed, and the storms of 1833 and 1867 helped to fuel scientific and popular interest in meteors, which had previously been considered a mere atmospheric phenomena, rather than evidence of extraterrestrial objects. More recently, Leonid storms were seen also in the years 1998-2002, with up to 3000 Leonids per hour. Understanding these storms through modelling can give us important clues about comets and their dust production, and of the dynamics of cometary dust trails and meteoroid streams. Draconids, named after the constellation Draco (the Dragon), also occasionally demonstrate unusual activity, such as major storms in 1933 and 1946, and, more recently, outbursts in 1998, 2005, 2011, and 2012. Leonid meteors come from a ‘Halley-type’ comet, 55P/Tempel-Tuttle, which has an orbit that stretches out the the orbit of Uranus, and hurtle into the Earth’s atmosphere at 70km/s. However, many meteors, such as Draconids, have rather lower speeds, of perhaps 20km/s – these come largely from ‘Jupiter-family comets’, which have the outermost part of their orbits near the orbit of Jupiter, and thus can suffer significant perturbations by this planet. These two streams are therefore complementary as test cases for the cometary trails model. Special Event – A Team Space Race – Yuri’s Night 2014 – Hunting Comets!: The announcement of the new application is the third and final reason for starting a team challenge! For this year’s Yuri’s Night, the 12th of April, which is also the birth day of the Constellation platform, we invite you for seven days of number crunching the workunits of Comet Trail and other Constellation apps. You and your team can join via BOINCstats. We also remind you to spend your weekend at one of the many Yuri’s Nigh events. You can check their website for a party near you! We will attend Yuri’s Night in our home town Stuttgart and we will have a fun day at the planetarium with great events and shows. So just leave your computers running and working for the team challenge, and have a great time outside!
  • First Results from Weather@Home 2014 UK Flooding Experiment
    11.03.2014 15:14 Uhr

    We have received an impressive response from the public after the launch of our experiment on the 4th of March. Our colleagues at the Oxford e-Research Centre, University of Oxford, estimate that nearly 1,000 new participants have subscribed to the project. Many thanks to all!

    We have now analysed the first 47 simulations that participants have run and they are plotted in the Figure below.

    weatherathome 2014 live results Alle BOINC Projektnews

    The blue dots represent the 2013/2014 winter as observed, and for this experiment, we received 20 simulations. For the “world that might have been” experiment, we received 27 simulations, which are shown as green dots.

    The smaller light green dots represent the individual patterns of sea surface temperature we estimated as the response of the climate system to man-made climate change. The smaller light green dots therefore represent the uncertainty in the human influence.

    At this stage, there are not enough simulations to make any conclusions about the role of climate change in the record wet winter 2013/2014. However, we want to illustrate to the public why we need such large ensembles, which is why we will show the “results” as they evolve.

    With this size of ensemble, the 2013/2014 winter as observed and as in the “world that might have been” are not distinguishable from another. Interestingly, our current wettest simulation comes from one of the  “worlds that might have been” simulations (the uppermost green dot) – but this could be entirely due to chance.

    We will also compare the rainfall totals with observations. For this, we will need to calculate the rainfall total from a dataset from the Met Office for exactly the same region as the one we defined for the simulations (land rainfall for South England and Wales).

    As this was a record wet winter, it has never been observed in the roughly 250 years of meteorological records, so we are looking at a 1/100-year event at least. As you can see from the figure, we are still only seeing 1/10-year events. We need more simulations to see any pattern, so please keep crunching!

  • New Weather@Home Project – Were Recent UK Floods Due to Climate Change?
    04.03.2014 10:08 Uhr

    You can help us answer the question: How much, if at all, was climate change to blame for the recent flooding in the UK?

    Help us answer this question in the latest weather@home experiment, launched today, with live results posted on the website daily over the next month. Nathalie Schaller explains the science behind this new project:

    The winter of 2013/2014 was the wettest ever recorded leading to severe flooding in many parts of the country. Many have been asking whether this level of extreme rainfall and the resulting floods are linked to climate change. This is not an easy question to answer, and we can never say that any particular flood was caused by climate change. However, we can ask and answer the question of how the odds of getting an extremely wet winter have changed due to man-made climate change: have past greenhouse gas emissions and other forms of pollution “loaded the weather dice” towards (or perhaps even away from) an event of this nature?

    In order to see if the dice have been loaded, we need to roll the dice many, many times, and that is what this experiment will do: we are going to run climate models for the recent winter thousands of times, creating an “ensemble” of models, which should show us the effect of any subtle loading. The ensembles need to be as big as possible to obtain robust estimates of the probability of rare events.

    So, to do this, we are asking for the help of the general public. We need to run two very large “ensembles” of weather simulations, one representing conditions and “possible weather” in the winter we have just had, and one representing the weather in a “world that might have been” if we had not changed the composition of the atmosphere through greenhouse gas emissions. By comparing the numbers of extreme rainfall events in the two ensembles, we can work out if the risk of a wet winter has increased, decreased or been unaffected by human influence on climate. We expect to obtain results within a month from launch, and plan to publish results as they come in, so you will be able to see the result as it emerges.

    We do not know what the results will be. It is absolutely possible that the experiments will tell us that climate change had nothing to do with the extremely wet winter we have just had.

  • yoyo@home: OGR-27: official results
    26.02.2014 23:00 Uhr
    Dear friends, is proud to announce the completion of OGR-27! It is almost five years ago to the day that we began on this exciting journey. Almost 20,000 of you joined us.. without whom, it would have been impossible. We have proven conclusively by the exhaustive search of all possible rulers that the previously predicted 27-mark ruler is indeed the most optimal one. We were confident that we would find a more optimal ruler during this search, but it was not to be. We expected it to take us seven years to complete this awesome task but thanks to your efforts recruiting your friends and co-workers to our effort and a little help from Moore’s Law, we did it in five. The best known ruler is 27/3-12-26-25-29-2-9-36-10-68-1-4-17-53-35-8-16-28-6-14-13-71-18-19-23-7 (length 553). Represented the other way, this is marks at positions 0 3 15 41 66 95 97 106 142 152 220 221 225 242 295 330 338 354 382 388 402 415 486 504 523 546 553. In total, we verified 302,621,586 unique stubs (2,526 with 3-diffs, 179,120 with 4-diffs, 6,457,815 with 5-diffs and 295,982,125 with 6-diffs), requiring each to have been completed at least two times independently and with an identical node count. Additionally, due to a client implementation bug in some early clients, we required all stubs to have been verified at least once by a client greater than v2.9109.518. This delayed us by a few weeks towards the end of the project but was necessary to ensure that no work was skipped. The shortest ruler was sent to us 11 times, with one user completing it twice. I will be writing to this user directly for some help picking lottery numbers! We will be sending some swag to the lucky winners and hope that you will join us as we move on to our next challenge!

  • 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.
