Short server outage relieved Nové okno
Due to a change of a central switch, the RNA World server was unexpectedly offline from yesterday around 4 pm until this morning around 10:30 am. The problem is now resolved, databases have been checked successfully for data integrity and everything should now run normal again.
As usual, the problem was reported in the RNA World Forum, which is located on a different server such that information can be passed on to you even when the RNA World server is offline.

Wegen eines kurzfristigen Austausches eines zentralen Ethernet-Switches war der RNA World Server von gestern ca. 16:00 Uhr bis heute Morgen um ca. 10:30 Offline. Das Problem wurde inzwischen behoben, die Datenbanken geprüft und alles läuft wieder normal.
Das Problem wurde wie üblich in den RNA World Foren erörtert, die aus Sicherheitsgründen auf einem anderen Server lokalisiert sind und daher auch dann funktionieren, wenn der RNA World Server Offline ist.

Windows 32-bit Application Progress Update Nové okno
Hello Cruncher,

I just wanted to let everyone know that we have just set up a test platform for Windows 32-bit which should allow us to begin work on building and testing a 32-bit Windows application for Separation with Modfit. I make no promises that this will be a quick process, but it is something we are working on.

Happy Crunching,

Jake

[edit]
Update: I currently have a CPU version of our Windows 32 bit application compiled and initial tests look good. I will be working on the Windows 32 bit OpenCL application for the rest of the night. Hopefully, that will be compiled by morning. If everything goes well in testing, I suspect maybe a release of a Windows 32 bit application for Separation on Monday.

LHC@Home - SixTrack Project News Nové okno
The members of the SixTrack project from LHC@Home would like to thank all the volunteers who made their CPUs available to us! Your contribution is precious, as in our studies we need to scan a rather large parameter space in order to find the best working points for our machines, and this would be hard to do without the computing power you all offer to us!

Since 2012 we have started performing measurements with beam dedicated to probing what we call the “dynamic aperture” (DA). This is the region in phase space where particles can move without experiencing a large increase of the amplitude of their motion. For large machines like the LHC this is an essential parameter for granting beam stability and allowing long data taking at the giant LHC detectors. The measurements will be benchmarked against numerical simulations, and this is the point where you play an important role! Currently we are finalising a first simulation campaign and we are in the process of writing up the results in a final document. As a next step we are going to analyse the second half of the measured data, for which a new tracking campaign will be needed. …so, stay tuned!

Magnets are the main components of an accelerator, and non-linearities in their fields have direct impact on the beam dynamics. The studies we are carrying out with your help are focussed not only on the current operation of the LHC but also on its upgrade, i.e. the High Luminosity LHC (HL-LHC). The design of the new components of the machine is at its final steps, and it is essential to make sure that the quality of the magnetic fields of the newly built components allow to reach the highly demanding goals of the project. Two aspects are mostly relevant:
    specifications for field quality of the new magnets. The criterion to assess whether the magnets’ filed quality is acceptable is based on the computation of the DA, which should larger than a pre-defined lower bound. The various magnet classes are included in the simulations one by one and the impact on DA is evaluated and the expected field quality is varied until the acceptance criterion of the DA is met.


    dynamic aperture under various optics conditions, analysis of non-linear correction system, and optics optimisation are essential steps to determine the field quality goals for the magnet designers, as well as evaluate and optimise the beam performance.


The studies involve accelerator physicists from both CERN and SLAC.




Long story made short, the tracking simulations we perform require significant computer resources, and BOINC is very helpful in carrying out the studies. Thanks a lot for your help!
The SixTrack team

issues with domain address and change Nové okno
I have changed the address to:

http://srbase.my-firewall.org/sr5/

due a blacklisted domain? There was no way to get it work again.

It looks like the old domain is working again but was deleted by myself in dyndns settings without any reworking.

Theory Tasks Available Nové okno
Theory tasks are available again. The downtime was caused by a suspected NFS related problem that resulted in a bad batch of jobs. The submission code has been hardened to detect this scenario in the future. The maximum jobs in progress limit has been put back to 2 and we will consider increasing this limit in the very near future.

CMS Application Now Available Nové okno
As the issues with the Theory application will probably not be fixed until after the weekend, the CMS application has been made available for everyone. Due to the slightly larger memory requirements, the the number of tasks that can be run simultaneously on a host has been reduced from 2 to 1. If for whatever reason you do not wish to run the CMS application, you can update your project specific preferences to run only the applications that you select. There will be no more tasks for Theory app until the problem has been resolved.

internet connection speed increased Nové okno
The speed went up from 2 to 25Mbit. The current download speed, not relevant for the server is 100Mbit instead 400Mbit because of an older 100Mbit cable. I have ordered 1GBit, should be arriving next week and will be replaced as soon as possible.

Theory Application job problems Nové okno
The Theory Application looks like it is getting a batch of bad input jobs from the MCPlots server. This is causing many task errors.
We are investigating… Please be patient.

We now suggest more people try the CMS Application which has been filled with work for you!
Go to your account page, then click "vLHCathome preferences", then "Edit vLHCathome preferences", then enable the "CMS Simulations" box, then click "Update preferences". Do a project update and you should get CMS tasks.

New QuarkStars application Nové okno
We have just started the tests of a new application. The main goal is to analyse
the possibility of observational detection of quark stars. These objects are
composed of quarks, i.e. particles smaller than neutron or proton. Quark stars are
nearly similar to neutron stars, but we may observe their impact on stellar
populations.

------------------------------------------

Właśnie uruchomiliśmy nową aplikację. Jej głównym celem jest analiza możliwości
obserwacyjnej detekcji gwiazd kwarkowych. Te obiekty składają się z kwarków,
czyli cząstek mniejszych niż neutrony czy protony. Gwiazdy kwarkowe są prawie
identyczne z gwiazdami neutronowymi, ale jest możliwe wyznaczenie ich wpływu na
populacje gwiazdowe

New Look for the Science Page Nové okno
Hello Crunchers,

I would like to announce a new look for our science page. In an attempt to bring the style of the science page more in line with that of the rest of the webpage, we did a visual overhaul of the page.

In addition to the visual reformatting, I did a lot of back-end reformatting of the page which should allow us to more easily edit it in the future. This is just the first step in our attempt to make the science page more interesting, complete and reader friendly. Look for a content update on the page to come in the new few weeks.

If you guys have anything you would like to see included on the page, or any general questions about the science we are doing with the project, feel free to post them here.

Happy Crunching,

Jake

UWM networking maintenance Nové okno
There is a need to upgrade the networking equipment at UWM and we want to do so before the new Web site launch. As a result, the Einstein@Home project will be down on Monday July 25, 2016; starting at 1300 UTC. That's 1500 for most Europeans and 0900 for East-coast North America. It's our hope that the network downtime will be less than 20 minutes.

During this time the Einstein@Home project will be off and the Web site will be unavailable.

Upcoming website relaunch Nové okno
After a long time of development and testing we're ready to relaunch our website!

The new site will feature a new design that's much improved over the current more than 10-year-old set of pages. The current Einstein@Home website is neither visually appealing by today's standards, nor is it particularly accessible because of the current structuring of information. First time visitors and potential new volunteers can be confused and we want to avoid that of course. We want to release a fully revamped website with an entirely new modern design as well as a complete overhaul of how we present information - all with an improved user-experience in mind.

Secondly, the current Einstein@Home website maintenance has always been cumbersome. Many content changes require a change of code! That's not the best way to get scientists to add or update content, like blogging about their current work or providing additional scientific content. We needed a way to facilitate that to expand the range of information we provide to our volunteer community, increasing their insight into what's going on behind the scenes. We chose to use Drupal, a true content management system, that allows us to do just that. But there's more: it's possible to extend Drupal's functionality in a way that it can fully include the functionality of BOINC's stock webpages. Other projects separated their content/science pages from their project management/community website, effectively providing two websites for a single BOINC project. That's something we wanted to avoid. We want a fully integrated, coherent solution and Drupal allows us to do that. However, the downside of this is a relatively complex implementation which is why it took us some time to develop it with our limited resources. Now we think it's time to release it.

We know that major changes like these will never please everyone, whether it's the visual design or the modernized site structure. We tried to minimize such negative effects by running a public test phase over at albertathome.org. That test phase started two years ago where we first invited our top 100 community power-users and our moderators. After that we fully migrated our test project and invited the whole community to give it a spin. We gathered your feedback and incorporated it into the now to be released version. Please note though that the new site still isn't 100% complete. It's going to be just the beginning - we upgrade its foundation to be able to build new offerings on top of it over the next months and years.

Long story short, here's the current release plan:

  • July 20th: first public announcement
  • July 25th: release plan update / heads-up
  • July 29th: final heads-up
  • August 1st-5th: website downtime / data migration / relaunch


Please note that during the first week of August the project's website will be shut down as we need to migrate all the existing community content in a coherent way. We try to keep the project itself running such that workunit distribution shouldn't be affected.

The Einstein@Home Team
