Launch of new Application

Hi everyone,

As some of you have noticed, there are new WUs in the system. We are starting with a small peak of work, but the idea is to maintain a continuous flow of new WUs.

This new part of the project is related to a Database of markers of the simulations. We are populating a database with relevant values of the simulations to make to scientist easy the way to make a exploratory study of the model or avoid making all the time the same simulations.

We are working on the interface of this database and how to integrate in our website, also, we are developing a post to explain more this idea of the Database of markers.

Happy New Year!! And Happy Crunching!

Since some days native ECM apps are available for ARM 64 and 32 bit Linux systems. No need anymore to install gmp-ecm package.


ECM: double credits for P2 workunits

The ecm P2 workunits require up to 10 GB RAM. Because of this they get double credits. Systems with less RAM should not get them.


UWM network maintenance

The UWM network operations need to shutdown our Internet connection for routine maintenance. As a result, the Einstein@Home project will be down on Monday January 2, 2017; starting at 1000 UTC. That is 1100 CET for most Europeans and 0500 EST for East-coast North America. Network downtime will be less than 20 minutes.




Heat Wave in the Arctic

The Arctic is currently experiencing a heat wave with temperatures forecasted to be more than 20 ºC above normal, following a very warm November and December. Such a heat wave has dramatic consequences for the local ecosystem and is also a striking example of how climate change is impacting the world today.

Historical temperature records reveal that the Arctic is warming more than twice as fast as the rest of the planet. Still, the recent heat and record-low sea ice for this time of the year are extreme departures from what has become normal now.

As part of the World Weather Attribution (WWA) team CPDN scientists have looked at observational data and model simulations, including weather@home to identify whether and to what extend human-induced climate change influenced the likelihood and magnitude of this extreme event.

The results the team found are that human-induced climate change is intensifying both the heat in the Arctic and increasing the frequency of such unusually warm periods. The analysis revealed that the temperatures experienced this November and December in the Arctic would have been extremely unlikely before the pre-industrial, pre-global warming days of the 1800s. This current North Pole heat event is still a rare occurrence — roughly two percent chance every year — even in our warmer world of today. Looking into the future, we found that, if nothing is done to slow climate change, by the time global warming reaches 2 ºC events like this winter would become common at the North Pole, happening every few years.

On 64 bit Windows version 700.02 is twice as fast as version 700.01. You should cancel all 700.01 tasks to get version 700.02.

Over the weekend, we passed 25% of the total work required to prove OGR-28. Also, we opened the 18-x stub space. :) Thank you for all of your efforts. Moo!

ecm application improvements
Source:  yoyo@home
vendredi 9 décembre 2016 00:00

I'm working on changes of the ecm application to handle larger B1 values for the elliptic curves and which runs only one curve and stage 1 and 2 in separated workunits. This allows us to attack an additional range of composites.Most changes on the backend are already done. But now the ecm application needs to be changed. Therefore no new workunits are issued. In the next days only resent and test wokunits will be available. The new workunits will have a P1 or P2 postfix.yoyo
