I'm not sure why yet, but the LetsEncrypt script didn't update the SSL certificate as expected. I ran it manually and it worked. If you are still having problems connecting, please let me know.
|Development project "face lift"|
mercredi 11 octobre 2017 10:16
The development project has been upgraded to use the latest BOINC upstream code. Thus, it now has a new look based on Bootstrap in accordance with other projects like SETI@home.
Your feedback and suggestions are, as always, appreciated.

|Another PPS-Mega Prime!|
lundi 9 octobre 2017 15:15
On 5 October 2017, 08:47:45 UTC, PrimeGrid’s PPS Mega Prime Search project found the Mega Prime: 911*2^3432643+1 The prime is 1,033,331 digits long and will enter Chris Caldwell's The Largest Known Primes Database ranked 208th overall. The discovery was made by Jochen Beck (dh1saj) of Germany using an Intel(R) Core(TM) i5-4670 CPU @ 3.40GHz with 8GB RAM, running Windows 7 Professional Edition. This computer took about 1 hour 25 minutes to complete the primality test using LLR. Jochen is a member of the SETI.Germany team. The prime was verified on 6 October 2017, 22:29:00 UTC by Georgios Magklaras (georgios) of Greece using an Intel(R) Xeon(R) E5-2650 v3 CPU @ 2.30GHz with 128GB RAM, running Linux. This computer took about 2 hours 28 minutes to complete the primality test using LLR. Georgios is a member of the Team Norway team. For more details, please see the official announcement.

Over the next week, some of the servers will be migrated in order to upgrade from SL6 to CC7. This will hopefully be transparent but if there are issues, this may be the reason.
|Discovering Climate Modelling at Curiosity Carnival|
mercredi 4 octobre 2017 17:45
Climateprediction.net team engage interest of hundreds of visitors in citizen science project during University-wide event at the Ashmolean museum
Last Friday saw 10,000 people engaging with university researchers at the Curiosity Carnival, Oxford’s contribution to European Researchers Night, which was celebrated by hundreds of cities across the continent.
The evening included a programme of activities for all ages and interests across Oxford’s museums, libraries, gardens and woods. CPDN researchers were at the Ashmolean Museum demonstrating 3D climate data modelled as part of the citizen science project climateprediction.net
The Magic Planet is a 3D globe projector which ran visualizations of climate model simulations of possible weather, including rainfall, and wind speed and direction. These climate models are used to answer questions about how climate change is affecting our world, to improve our understanding of the climate system and help manage future climate risk.
Running these models takes a huge amount of computer power and time, but the world’s largest climate modelling experiment climateprediction.net speeds up the process by using the downtime on thousands of volunteers’ home computers across the planet.
Recently the researchers found that climate change increased the chances of seeing a European summer as hot as 2017 by at least a factor of 10 and a heat wave like Lucifer by at least a factor of four. Such summer heatwaves with temperatures over 40C could become normal by 2050.
Team members David Wallom, Sarah Sparrow, Friederike Otto and Sihan Li (Meredith) were on hand in one of the upper galleries of the Ashmolean Museum to explain the data being visualized on the Magic Planet 3D projector, and to appeal for more volunteers for the climate modelling programme. Visitors to the stand ranged from school children to fellow researchers writing PhDs on climate science. They were also joined by one of the climateprediction.net community’s longstanding moderators, Maureen Villar.
Over 100 interested people immediately joined our volunteers from all over the world who already contribute their computer’s downtime to the world’s largest climate modellingexperiment .
|Open Zika Researchers Continue Calculations, Share the Wealth, and Spread the Word|

The OpenZika researchers are continuing to screen millions of chemical compounds as they look for potential treatments for the Zika virus. In this update, they report on the second stage of the project, using a newly prepared, massive library of 30.2 million compounds that are being screened against the Zika virus proteins. They also continue to spread the word about the project.

The server will be upgraded today to use the latest version of the Web interface. We anticipate that things may break so expect some instability over the next few days. What we discover by doing this will hopefully make the upgrade of the production server smoother.
|nbody 1.66 release|
lundi 2 octobre 2017 22:17
I just released version 1.66 of Nbody. This version has a newer version of the likelihood comparison algorithm which is used when comparing our test histograms with the client-side simulations. With this update we are hoping to have much better convergence in our parameter searches.
As always, please let us know if there are any issues.
