  • Scheduled Server Maintenance 2/21

    Veröffentlicht: Februar 21, 2018, 4:15pm CET
    Hi Everyone,

    There will be a scheduled server outage today around 1pm. This should be a brief outage while we install some additional RAM in the server.

    Thank you for your understanding.

  • [all] disk issues on server

    Looks like we're experiencing some kind of disk issue on the server. I've submitted a support ticket but in the mean time had to shut down the daemons. I hope we have this back up and running shortly.

  • Paper presents tool for assessing risk of hydro-meteorological extremes in UK

    Veröffentlicht: Februar 19, 2018, 2:47pm CET by Julie Meikle

    Extreme weather events such as droughts and heavy precipitation can have large impacts on society and the economy, so ensuring that society is well prepared to face such events will have multiple benefits.

    Anthropogenic climate change is expected to have an impact on these types of events: warm temperature extremes and heavy precipitation extremes have been shown to have increased due to human greenhouse gas emissions and these are projected to increase in the future (IPCC, 2013).

    Properly assessing the associated impacts and uncertainties is critical for adequate adaptation, however, the application of risk-based approaches often requires large sets of extreme events, which are not commonly available.

    A new paper co-authored by climateprediction.net researchers presents just such a large set of hydro-meteorological time series for recent past and future conditions for the United Kingdom based on weather@home2, a modelling framework consisting of a global climate model driven by observed or projected sea surface temperature and sea ice which is downscaled to 25 km over the European domain by a regional climate model.

    Future projections show small precipitation increases in winter but large decreases in summer on average, leading to an overall drying, consistent with the most recent UK Climate Projections (UKCP09) but larger in magnitude than the latter. Both drought and high-precipitation events are projected to increase in frequency and intensity in most regions, highlighting the need for appropriate adaptation measures.

    Overall, the presented dataset is a useful tool for assessing the risk associated with drought and more generally with hydro-meteorological extremes in the UK.

  • GFN-262144 Mega Prime!

    Veröffentlicht: Februar 19, 2018, 1:26pm CET
    On 15 February 2018, 02:15:40 UTC, PrimeGrid’s Generalized Fermat Prime Search found the Generalized Fermat mega prime: 4246258^262144+1 The prime is 1,737,493 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 7th for Generalized Fermat primes and 57th overall. The discovery was made by Rob Gahan (Robish) of Ireland using an NVIDIA GeForce Titan X in an Intel(R) Core(TM) i7-5930K CPU at 3.50GHz with 32GB RAM, running Windows 10 Core Edition. This GPU took about 23 minutes to probable prime (PRP) test with GeneferOCL3. Rob is a member of the Storm team. The prime was verified on 15 February 2018, 02:18:23 by Daniel Frużyński ([B@P] Daniel) of Poland using an NVIDIA GeForce GTX 1070 GPU in an Intel(R) Core(TM) i7-2600K CPU at 3.40GHz with 16GB RAM, running Windows 10 Professional Edition. This GPU took about 20 minutes to probable prime (PRP) test with GeneferOCL3. Daniel is a member of the BOINC@Poland team. The PRP was confirmed prime by an Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz with 16GB RAM, running Microsoft Windows 10 Professional. This computer took about 4 hours 37 minutes to complete the primality test using LLR. For more details, please see the official announcement.

  • Experimental QC app for Windows 10

    Veröffentlicht: Februar 18, 2018, 5:37pm CET
    Dears, have a test QC app for Windows 10. QC relies on the PSI4 software which does not have a Windows version. Therefore, we'll rely on WSL (Windows Subsystem Linux - a nice lightweight Linux-like environment to run native apps inside Windows), provided by Microsoft in the recent version of Windows 10. Unfortunately I don't think there is a way to prevent the distribution to non-W10 and non-WSL hosts. Therefore, to run QC tasks, the first time only you will have to prepare the environment as follows...
    1. Enable WSL. The procedure unfortunately varied over time, the most current being here
    2. Install the Ubuntu distribution via the App store (it is free of course).
    3. Launch the newly-installed Ubuntu command line via its icon. It will request a password for a new user being created. Provide one.
    4. Now you have a working Ubuntu environment. As for the native ones, manual installation of the gcc package is required. So, in the Ubuntu bash prompt, execute the following commands (the prompt reads like "(your_chosen_user)@MACHINENAME:path") sudo apt update sudo apt install gcc

    (Of course, if you already have WSL installed, you will just need step 4.) Technical details: In addition to the normal Boinc project and slot directories, the app will use space in the /tmp/gpugrid_miniconda directory inside your WSL installation (not directly accessible from Windows). Unlike the Linux app, the space is not automatically cleaned up when you uninstall BOINC or reset the project. To clear it, either uninstall Ubuntu, or remove it from the Ubuntu prompt.

  • [all] server issues

    Veröffentlicht: Februar 14, 2018, 5:38am CET
    Looks like we're experiencing some issues server side where the file_deleter daemon isn't working right. I've cleaned up a little space and am running things to fix workunit/resuilt states in the database so the file deleter does it's job. Hoping to have things fixed by the morning but in the meantime things will be down while the cleanup is happening.

    Hi Everyone -- got some really interesting results from the last round of searches and we submitted a publication on them last week. Will get a copy out to you soon once we find out if it was published! I've started up a new batch of searches so let me know if you have any issues with these.

  • Changing Workunit Priority to 1 from 0

    Veröffentlicht: Februar 9, 2018, 10:10pm CET
    Hi Everyone,

    In order to use the "Use Reliable Host" feature built into the BOINC server software, we must change our workunit priority to 1 from 0. I am implementing this now and will check in over the weekend to make sure everything is running well.

    If you have any questions or see any issues, please let me know.

    Due to a database issue last week, task generation is delayed and we need to clean up stuck workunits. The project daemons will be on and off this morning while we try to debug a problem with the BOINC transitioner.

  • Can climate change impacts be inventoried? Dr Friederike Otto explores

    Veröffentlicht: Februar 1, 2018, 11:54am CET by Julie Meikle

    Climateprediction.net’s Dr Friederike Otto will be talking on extreme event attribution at the AAAS Annual Meeting (American Association for the Advancement of Science) in Austin, Texas, this February.

    Her talk – Extreme Event Attribution: Towards an Inventory of the Climate Change Impacts – on Sunday 18th February, is part of the Understanding Causality to Inform Decision-Making Under Uncertainty session, in the Climate and the Environment Track. The theme for the Annual Meeting 2018 is Advancing Science: Discovery to Application, which aims to explore what new avenues for interaction between basic and applied research might be investigated, and how we can encourage broader participation from every sector and demographic to meet today’s needs and in the future.

    In the Understanding Causality session speakers will discuss how extreme events can be attributed to climate change; how causality can be detected within the complex dynamics of ecosystems; and how the strength of causal inference can be quantified; addressing both the strengths and limitations of these emerging methods.

    Dr Otto will explore how, with advances in attribution, an inventory of the impacts of overall climate change could now be possible, building on attribution studies of individual extreme events.

    The American Association for the Advancement of Science is an international non-profit organization dedicated to advancing science for the benefit of all people.

    Follow the event (Feb 15-19) on Twitter @AAASmeetings and Dr Otto @FrediOtto.
