- climateprediction.net: Potential influences on the United Kingdom’s floods of winter 2013/14
16.09.2014 15:17 Uhr
A new paper has been published in Nature Climate Change by climateprediction.net scientists including Chris Huntingford, Friederike Otto, Neil Massey, Nathalie Schaller and Myles R. Allen.
The paper, entitled, “Potential influences on the United Kingdom’s floods of winter 2013/14″ looks at the possible drivers behind the floods last winter, which affected large parts of the UK.
Dr Chris Huntingford, from the Centre for Ecology & Hydrology and the lead author of the paper, explains:
In this paper, along with my co-authors, we have tried to provide a summary document that collates and discusses all possible drivers behind the major flood events that affected the UK last winter. It has three themes.
First, a very brief overview of the large-scale meteorological events leading up to the storms is presented. None of the individual rainfall events was unprecedented, but the weather patterns behind them persisted for three months causing a near-continuous succession of Westerly storms. This had the cumulative effect that for much of the Southern UK, the total winter rainfall was record-breaking. Preliminary analysis suggests that particularly warm ocean conditions and heavy rainfall in and around Indonesia triggered wind patterns across the Pacific that travelled northwards before ultimately drawing cold air down across the USA. This in turn forced a particularly strong and persistent Jet Stream across the Atlantic and towards the UK. The Met Office is now studying this sequence of events in significantly more detail. In our paper, we show how the winter storms affected river flows, and place the events within a historical context.

Second, questions mount as to whether fossil fuel burning could have a role. We have reviewed existing research literature for Earth system factors that may be both changing through global warming, and additionally are identified as influences on storm features for the UK. As expected, this confirms how complex and inter-connected the climate system is. Multiple possible UK rainfall drivers are identified that link to the state of the oceans, the atmosphere and sea-ice extent. Interestingly the recent rapid decrease in Arctic sea-ice that is widely attributed to global warming, for the UK at least is often portrayed as likely to bring more Easterly winds and colder conditions. The previous three winters had these features for some of the time, in marked contrast to winter 2013/14. Although the precise details of linkages between changing large-scale features of the climate system and UK rainfall intensity are still not fully understood, we hope our review article is a complete list of such connections. To apply that frequently used expression, we trust there are no “unknown unknowns” lurking out there we have yet to consider.
Third, we provide some thoughts on how best to proceed. Assuming that we do have a pretty good idea of all drivers expected to affect rainfall, and that require on-going computer modelling, three challenges are noted. These are: (1) the need for continued enhancement of physical process representation via ever better parameterized differential equations of the oceans, atmosphere and ice sheets, (2) increase further the numerical grid resolution of climate models, on which these equations are calculated and (3) undertake significantly higher numbers of simulations, all with slightly different initial conditions, creating a large ensemble of projections. The call for better resolution is because some characteristics of storms occur on fine spatial detail, thus needing small spacings between gridpoints on which calculations are updated. The request for large ensembles is because extremes, by definition, are rare events, and so we need to ensure that all heavy rainfall “return times” are fully sampled. This is both for pre-industrial and for raised levels of atmospheric greenhouse gases.
During the major flood events affecting much of Southern England from December 2013 to February 2014, it was inevitable that questions would be asked as to whether fossil burning could have a role. It is always (and correctly) stated that no single observed extreme event can be formally attributed to human-induced changes to atmospheric composition. But a statistic can be derived that assesses any changing probability of a particular extreme event occurring, a quantity sometimes referred to as “Fractional Attributable Risk”. By satisfying the three challenges we listed above, we will get near to stating if humans are increasing, decreasing or leaving invariant the chances of rainfall events of the type witnessed. However, even now limitations remain on computer speed and resource, and expenditure on climate research can only ever be finite. Hence an especially lively debate will now occur as to what constitutes the optimal balance between pursuing these three challenges, in order to get us most quickly towards the required answers.
Anyone studying meteorological systems, or the full Earth system, soon realizes of course how tightly coupled all features are of the climate system. In this review, by trying to collate in to a single paper the main factors affecting UK rainfall, this did though provide a timely reminder of such comprehensive interconnections. Understanding these further suggests a very interesting time lies ahead for climate change research.

- SIMAP – Similarity Matrix of Proteins: Network outages and service limitations Sep 13/14
13.09.2014 21:08 Uhr
The network connections within and to the university of Vienna was broken for 8 hours on Sep 13. Additional network outages may occur on Sep 14. We have therefore stopped the generation of new workunits. The project will return to its full functionality by Monday Sep 15. We are sorry for these unexpected problems. Best regards Thomas
- Wildlife@Home: traveling this week
13.09.2014 00:10 Uhr
Of course while I travel halfway around the world the spammers decide to come out in full force. I’m currently in Ljubljana, Slovenia for the 13th International Conference on Parallel Problem Solving from Nature, which should be really interesting! I’ll be checking up with the webpages and things like that while I’m gone (especially to deal with the stupid spammers), but am not sure how much time I’ll have for application updates as I need my desktop at home to do all the compiling. I’ve made the changes to the DNA@Home code to get the application updated which should fix the validation issues, so when I get back I’m hoping to push out a new application version for that.
- PrimeGrid: SR5 Mega Prime!
12.09.2014 18:32 Uhr
On 17 August 2014, 13:00:59 UTC, PrimeGrid’s Sierpinski/Riesel Base 5 Problem project eliminated k=133778 by finding the mega prime: 133778*5^1785689+1 The prime is 1,248,149 digits long and enters Chris Caldwell’s The Largest Known Primes Database ranked 56th overall. This is the largest known base 5 mega prime. 38 k’s now remain in the Sierpinski Base 5 Problem. The discovery was made by Guo Hua Miao (前朝遗少) of China using an Intel Xeon(R) CPU E5-4617 @ 2.90GHz with 504GB RAM running Linux. This computer took about 27 hours and 9 minutes to complete the primality test using LLR. Guo is a member of the Team China team. For more details, please see the official announcement.

I’ve sent out a new batch of work units which should (hopefully) fix the validation problem the other ones were having. Let me know how these are running. Feel free to cancel anything starting with ‘test_hg19_1_…’.
- Wildlife@Home: please cancel all the test_hg19_XXXX workunits
09.09.2014 02:00 Uhr
Looks like there’s a problem with these. They’re printing too much out to standard error which is busting the validator. I need to alter their command line options to fix these. On another note, how is the runtime for these — should I make them longer? At what % should they checkpoint (I was thinking every 5%).
- Wildlife@Home: longer DNA@home workunits
08.09.2014 22:02 Uhr
I’ve created a new set of work units from DNA@Home using a new data file (from human genome revision 19 — hg19). These should run a bit longer than the other work units, so please let me know if the time estimates and credit is okay. They’re actually not as long as I’d like them to be, so depending on how things are working work units after this could be 10x longer.

- Moo! Wrapper: New app v1.4 with OpenCL support deployed
07.09.2014 05:18 Uhr
Finally we have a newer application version that supports OpenCL! Updated versions of both AMD/ATI Stream and OpenCL apps for Windows have been offered by our server since yesterday to participants meeting requirements.
These apps require BOINC Client v7.2.28 or newer and Windows XP or newer. The Stream app is not available to AMD Radeon HD 7870/7950/7970/R9 280X series (Tahiti) or newer cards due to compatibility issues. OpenCL app is preferred for those cards.
The old app version is still available for systems running older BOINC Client. However, if your system has multiple GPUs, please consider updating it’s BOINC Client to a support version. There are known issues running the old app on systems with multiple GPUs. New apps fix these by running one cruncher per device.
For detailed app change history, please read application changelog. For latest requirements enforced by our server, please read latest requirements.
Please report any problems you might encounter with new apps and our changes. Especially if you no longer get any work from our server where you previously did. You can report them by posting at our forum.

- Moo! Wrapper: Server moving
27.08.2014 07:28 Uhr
I’m migrating our primary server to a new host that has a newer OS and more modern hardware. It’s also closer to our DB server so any delays between the servers should be minimized. To top this all off, it’s also cheaper.
As things are changing there might be one or more disruptions on services but I’ll keep an eye on things and don’t expect any loss of work as soon as dust settles. No action is needed on your part unless you are hard coding our server IP address somewhere like your firewall rules. In which case you should prepare to change the address and think about using name (moowrap.net) instead of hard coding an IP.
I’ll let you know when I’m done. Thank you and happy crunching with a snappier server!
