Results of the deepest all-sky survey for continuous gravitational waves on LIGO S6 data Nové okno
The analysis of the results from the four combined Einstein@home runs on S6 LIGO data are out: Results of the deepest all-sky survey for continuous gravitational waves on LIGO S6 data running on the Einstein@Home volunteer distributed computing project

We will shortly also submit the paper for publication in Physical Review D, but we wanted to share these results with you immediately. We have not yet found a gravitational wave signal but we could bound the height of mountains on neutron stars in the neighbourhood of Earth. For example, we can now say that there is no neutron star spinning at 9 ms or faster within 100 parsecs of Earth with a bump higher than 1 cm!

cable provider down Nové okno
As you noticed there was no internet connection to the server. My cable provider went down 4h ago and it was not possible to call the service center (also down), this was a crazy day. I have setup the new IP address for the server so the connection should be working again. If you have any issues tell me please.

Apologize for the inconvenience.

ESP Sieve shutting down July 31st Nové okno
The ESP-Sieve has reached its optimal sieving depth and will be shut down soon. If you're close to that next badge level, now is the time to get it. The actual date will be depend on when work runs out, but we will make sure there's work until at least the 31st. More information and discussion can be found here: http://www.primegrid.com/forum_thread.php?id=6883

Nbody Release 1.62 Nové okno
Hey All,

I just released a new version of nbody, v1.62. In this release we did a few things:

We realized that different platforms were giving slightly different results. This was a problem as it would throw off the search algorithm and also may cause validation issues. Turns out there were an number of reasons for this. One was that the likelihood calculation was performed using single precision on a double precision application. So we changed it to be a double precision calculation.

Also, and most prominently, we realized that the windows command prompt and unix terminal read in inputs with different precision. One would cut the value of after about the 10th decimal place. This mean the actual input parameters were slightly different! Therefore, we forced the rounding of the input parameters after the 9th decimal place. That seemed to do the trick mostly.

Finally, we realized that our building mechanism was not building linux binaries statically. When we tried with our current mechanism we ran into a can of worms known as seg faults. It was a nightmare trying to find it so we decided to temporarily switch our building mechanism. I tested them on all our computers and it seems to work. But, as always, let me know if something goes awry.



Thanks everyone for your continued support!

Universe@Home and BOINC Pentathlon on admin point of view Nové okno
Better late than never, so a few words about how Pentathlon looks from the
administrator’s point of view

As I have explained before, loads of pressure hits the server with thousands of
computers connecting with "bunkered" WU's. Usually we had ~45'000-50'000 tasks
in progress and just before the start the quantity grew up to 250'000 and later
stayed at the level of about 220'000-240'000 tasks in progress.

As you probably noticed from the picture showed in the other topic the only
problem we had was with hard disk speed because of thousands database operations
in the background of other server tasks.

As you can see in the picture below, almost in the whole Pentathlon competition
time disk utilisation was at 100% or just below it. We usually have stable disk
utilisation at 40-50%.

In the middle of the competition I also switched off all unnecessary daemons and
other software which usually works on our server and even without them the
server was off-line for 30 minutes.

Now, the situation is stable. We still have more tasks in progress than before
the competition (which makes us very happy) and we will also prepare to buy some
SSD's asap :)

Thank you very much for your power in Pentathlon and obviously for every day
with us and our tasks :)


Lepiej późno niż wcale. Tak więc kilka słów o tym jak Pentathlon wyglądał z
punktu widzenia administratora

Jak tłumaczyłem wcześniej, bardzo duże obciążenie pojawia się na serwerze gdy
tysiące komputerów podłączą się ze swoimi "zbunkrowanymi" WU. Zwykle mamy
~45'000-50'000 zadań w toku, a zaraz przed rozpoczęciem ta ilość wzrosła do
250'000, a później pozostała na poziomie 220'000-240'000 zadań w toku.

Jak pewnie zauważyliście na załączonym obrazku, jedyny problem, jaki mieliśmy to
opóźnienia w operacjach dyskowych i wynikał on z tysięcy operacji na bazie danych.

Również widać na poniższym obrazku, że prawie przez cały czas trwania konkursu
Pentathlon wykorzystanie dysku było na poziomie 100% lub nieco poniżej. Zwykle
mamy wykorzystanie dysku na stabilnym poziomie 40-50%.

W środku konkursu wyłączyłem wszystkie zbędne demony i oprogramowanie zwykle
pracujące/działające na serwerze i nawet bez nich serwer był niedostępny przez
30 minut.

Teraz sytuacja jest stabilna. Nadal mamy więcej zadań w toku niż przed
konkursem (co bardzo nas cieszy) i będziemy się przygotowywać do kupienia dysków
SSD tak szybko jak to możliwe.

Dziękujemy bardzo za zaangażowanie w Pentathlon i oczywiście za każdy dzień z
nami i z naszymi zadaniami :)

New Version of MW@home for Mac (1.37) Nové okno
Hey Mac Users,

I just released a new version of MilkyWay@home Separation that will run much faster on Macs. (Expect about a factor of 7-8 speed up). If you guys see any issues with the new application post them here.

I only released this new application under the official project and not the Modfit project since we are slowly phasing out the Modfit project.

Enjoy the weekend,

Jake

Disk space limit decreased to 4GB Nové okno
Hi all,

To make more effective use of volunteers running ramdisks we have reduced the disk space limit from 6.5GB to 4GB. See thread here

http://atlasathome.cern.ch/forum_thread.php?id=505

We see that most tasks use at most 2.2GB so this should be safe, but please notify us of any problems related to this change.[/url]

 
MalariaControl 2016-06-21 16:34:35
Status and plans as of June 2016 Nové okno
Dear Malariacontrol.net contributor, It's been a while since we announced that malariacontrol.net will be back after a short period of maintenance and upgrading, and you are probably wondering why you are still not receiving new workunits. By now, it looks like malariacontrol.net will not be sending out workunits any time soon. The reason for this is that, unlike when we started out more than ten years ago, volunteer computing is currently not the most efficient and cost-effective approach for providing the computing resources necessary for the simulation studies. Developments in high-performance computing and institutional arrangements have made computing infrastructure accessible to the malaria modeling project which was simply not available ten years ago. Also, the staffing profile of the project has changed over time, and maintenance and further development of the volunteer computing platform are more challenging these days than before. Therefore, at the moment we cannot justify the significant investment required to upgrade the malariacontrol.net-specific components of the BOINC server for the next phase of the project. This is a good moment to look back on more than 10 years of running malariacontol.net, and the achievements you contributed to. We believe that the project has substantially improved knowledge of malaria and malaria control. The scientific articles which are listed on the BOINC wiki give an overview of the achievements. In addition, some of the simulation experiments we ran on malariacontrol.net have formed the basis of technical reports and software tools which helped inform important policy decisions. We will keep the malariacontrol.net server running for now. It may be that sometime in the future, we will have applications that will make this again the best way for running simulations, so please keep your BOINC client connected to malariacontrol.net. Thank you very much for your generous support over the last 10 years! On behalf of the malaria modeling team, Nicolas --

Scheduler and vbox update to detect 64-bit enabled computers Nové okno
The BOINC scheduler has been updated to detect 64 bit machines that do not have the virtualization hardware extensions enabled. Also vboxwrapper has been updated for better error handling, and vboxwrapper 26193 is now deployed for Windows and Linux for the Theory, CMS and LHCb applications. This setup has been tested in our dev project.

Many thanks to Rom Walton for providing these changes to the BOINC code.


The CMS and LHCb applications seem to run fine with the new wrapper, and after fixing a permission issue, also the Theory simulations now use this wrapper.

The positive effect of all the problems among the Pentathlon: this project is now somewhat challange capable.


Hopefully! The last time we had a challenge things ran smoothly, but I think we're a lot better off in the long term now.

Forums seem to have significantly sped up as well now.

Running Modfit on MilkyWay@home Nové okno
Hello Crunchers,

Now that MilkyWay@home Separation Modfit has been running for a year as a stable application, we are going to be releasing it as the official MilkyWay@home application under our main project. This means we will slowly (over the next month) be phasing out the dedicated Modfit project as it will be redundant. Additionally, this means some extremely old systems may no longer be supported on the MilkyWay@home project. These include Windows 32-bit systems, and very old (CAL) GPUs. If you are noticing compatibility issues with your system after we begin the change next week please post them here.

Thank you all for your continued support.

Jake

[edit]
Modfit is now up and running on the main application. If you are seeing any issues please let me know here.

Thanks.

@Travis:

Yes, it's working much better now. Try to optimize all settings and this project will work like a charm. We have a lot of workunits/tasks to catch up.

SSS is a very important project for mankind.

Thank you Travis!

A brand new paper from the Baker lab in Nature! Thank you yet again for your contributions, Rosetta@home volunteers. Although R@h was not directly used for these designs due to size and memory limitations, your contributions are instrumental in Rosetta development enabling such science. Thank you! "Design of a hyperstable 60-subunit protein icosahedron" describes the design of a 20-sided nano-sized particle that could be used to deliver drugs or to develop powerful new vaccines. Author and Baker lab graduate student Yang Hsia spoke on a Nature podcast on the work. Have a listen to hear about this awesome work from the protein design experts themselves! Links below.

[subset_sum] status update 2 Nové okno
I've removed a number of workunits and the feeder is now blazing along extra fast. Work should be flowing significantly better.

Now that work is flowing, I'll be working on updating the work generator for SubsetSum@Home to make sure it keeps a minimal (<10k) number of workunits available, but auto generates them as needed to prevent this from happening again. Hoping to have the updates in tonight.

Thanks for your patience in dealing with all this, especially during the midst of a pentathalon!

It looks like the extra RAM didn't fix the issue. Right now I'm going in to remove some of the workunits which haven't had results sent out yet. This should speed up the feeder. I'll leave enough WUs/results available to keep work flowing while I code up changes to the work generator to make sure this situation doesn't happen again.

I'll keep you all posted as things progress. I hope to have the issue resolved sometime tonight (I'll stay up till it's fixed!).
