Planet BOINC

The donations system is up and running again.

The site's downtime was caused by hardware issues during the weekend. We might have some more troubles in the next few days. We are sorry for the inconvenience!

The project will be offline for approx. two hours tomorrow Tue Feb 9 from 10.00am CET for maintenance.

One week till the start of the 2010 Challenge Series with the Year of the Tiger. A 3 day (14-17 Feb) Challenge is being offered on PrimeGrid's Proth Prime Search (LLR). Come join us as we stalk the primes. Application builds are available for Mac, Linux, and Windows. For more information, please see this forum thread.

GIMPS has found another Fermat factor, a 54 digit factor to F14!!! What makes this unique and exciting is that it is the first factor for F14. It was found by Tapio Rajala of Finland. For more information on this discovery, see this mersenne forum thread. For more information about the factoring status of Fermat numbers, please see Wilfrid Keller's Prime factors of Fermat numbers site.

Due to a spam attack, we have shut down temporarily the donations to GPUGRID. We will inform you when they are open again.

Jarifa now supports polls, allowing Jarifa users to vote for their most valuable BOINC projects. The users have to log in, and then they will be able to vote for the projects that Jarifa offers them. With this new feature, projects like Extremadurathome can leave the power of choice in the community, by enabling this feature. The software enables the two most voted projects, each day, week, month or year (it is set up by crontab, so it is possible to configure it in a wide range of time units) automatically.

We have sent 1000 WUs for the new beta application. Please note that they are actually production WUs already.

The new Nvidia application is now out in beta. It is available by accepting beta work from GPUGRID.

Sorry about the earlier outage. Everything should be up and running smoothly now.

We are kicking off the 2010 Challenge Series with the Year of the Tiger Challenge which just so happens to coincide with Valentine's Day in the West. The Tiger is the third sign in the Chinese Zodiac cycle, and it is a sign of fearlessness. It is considered incredibly brave, evidenced by its willingness to engage in battle. So whether it's your love of Tigers or love of primes, please come join us in an East & West fearless attack on Proth Primes.A 3 day (14-17 Feb) Challenge is being offered on PrimeGrid's Proth Prime Search (LLR). Builds are available for Mac, Linux, and Windows. For more information, please see this forum thread.

This week Docking@Home starts its crossdocking phase, we will perform docking of a given ligand with slightly different conformations of the receptor, then our postprocessing algorithm will select the best ligand conformation. This process simulates the flexibility of the protein resulting in more realistic simulations

From now on, it is possible to vote for those projects that you like most in the following web site: http://boinc.unex.es/extremadurathome. In this web, you can choose which project is your favorite and view the results of the poll. Thanks to this new feature, only registered users will be able to vote.

 

To vote you only have to log in (with your user name and password) and choose a project from a list of projects. Additionally, you will be able to know your rank position.

A new AP25 (Arithmetic Progression of 25 primes) has been found. It is the 11th discovered. The finder is Jan Stenzel (Jan Stenzel) of Poland. He is a member of the BOINC@Poland team.The AP25 progression is written as 49644063847333931+7851809 *23#*n for n=0..24. It was found by an Intel Core i7 860 @ 2.80GHz running 64 bit Windows 7. For more details on this find and the AP26 search, please see this forum post.

Tomorrow D@H will start crossdocking, it is a critical change but we expect we will move smoothly. Please be patient in the event of possible crashes

The Tour de Primes begins. Come join us in laid-back competition in tribute to the number 2...the first prime and the only even prime. The prizes are simple colored jerseys . Yellow for the most primes, Green for the highest prime score, and Checkered for the most primes on 17 Feb. No pressure or stress other than what you put on yourself. :) For more information, please see Tour de Primes 2010.

Our database is currently pretty slow, due to a large number of ABP2 results. We are taking measures to keep the project running, but with a few restrictions: The scheduler (task sending and reporting) is disabled part of the time (clients will see a 'temporarily down for maintenance' message). The server status page has been disabled. We'll also reduce the time results are kept in the database. Hopefully we will be able to return to normal operation in a few days.

Progress has been made with the new application in development; read more about the science here.

On the eve of the Tour de Primes 2010, we are happy to announce that PrimeGrid is partnering with Seventeen or Bust to help solve the Sierpinski problem! This finally brings PrimeGrid full circle with SoB/PSP primality testing as well as combined sieving. Special thanks to Louis Helm of Seventeen or Bust for helping to make this collaboration possible!For more details on the new search, please see this forum thread.

Los dos schedulers parece que desde el sabado estan considerando no enviar trabajo a la mayoria de las maquinas. He subido 24 horas los tiempos limite a ver si era eso, pero no lo creo. Los logs muestran todo el rato algo asi:

Y que si quieres arroz catalina. Igual tenermos que resetear las preferencias de los usuarios el lunes :-(

Account creation active again as usual.

New Workunits: the calculation of similarities and features of new sequences, that were imported from protein databases into SIMAP until the end of January, will start in the morning (UTC) of January 31.

February is a couple of days away which means it's time for the Tour de Primes. 2 is the first prime number...and the only even one. Therefore, we have declared February, the 2nd month, as prime month.We're offering a small competition in tribute to this unique prime number. There are no points to be gained or awards to be won...just a simple colored jersey (Yellow, Green, and Checkered) at the end of the month. No pressure or stress other than what you put on yourself. :) For more information, please see Tour de Primes 2010.

I really think I fixed them now. Finally!

We have disable account creation temporarily. GDF

I'm lowering the purge time (sorry) to help speed up the database. This should hopefully improve response time for the webpage and downloading new workunits.

I've implemented optimistic and pessimistic validation for the particle swarm searches now as well (as opposed to just the differential evolution searches that were running before). I've tested them quite a bit so I think it's working correctly, but just warning you the server might crash a few times in the next few days while I get all the bugs sorted out. Let me know if you're having any problems with the ps_s222_opt_1, ps_s222_pes_1 workunits.

Hoy hemos sacado a producción Cuanticables.

Cuanticables es un proyecto desarrollado en la Universidad de Buenos Aires por el área de Materia Condensada - Sistemas Mesoscópicos. La aplicación consiste en el cálculo de propiedades de transporte electrónico en sistemas nanoscópicos desordenados. Básicamente se trata, mediante la realización de sistemas con desorden aleatorio, determinar las propiedades estadísticas de la conductancia de un sistema de muchos canales sobre el que se induce transporte electrónico mediante la aplicación de una diferencia de voltaje. Hay mas información en www.ibercivis.es

 

I updated the server with the fix for people whose app_plan.xml with count set 1. Let me know if it worked.

The 16th of January of 2010, the TV show Conecta-T played a report about the Extremadurathome.org project. Extremadurathome.org is a social project that tries to popularize science among citizens.

Extremadurathome.org is using Jarifa to manage volunteers, which has more than 400 volunteers and 700 computers donated to different research projects.

The full episode can be viewed in the following link.

Some of our users have said that they're having problems using the ATI application on an anonymous platform; when they have settings that specify no cpu, and no nvidia gpu work, and only ATI gpu work. If anyone is having this problem please post your app_info.xml so I can send it to the boinc_dev mailing list to get it debugged. thanks! --Travis

I applied a patch which should hopefully fix the CPU utilization of the GPU applications, which was causing some users problems with running the CPU app alongside the GPU app. Let me know how it works.

The factor, which was found by Jeff17, is now recorded as the biggest one in the XYYXF ecm top record list.

A new AP25 (Arithmetic Progression of 25 primes) has been found. It is only the 10th discovered. The finder is Gerrit Slomma (roadrunner_gs) of Germany. He is a member of the Special: Off-Topic team.The AP25 progression is written as 46428033558097831+12893265*23#*n for n=0..24. It was found by an Intel Core2 6400 @ 2.13GHz running Linux. For more details on this find and the AP26 search, please see this forum post.

The (re-)discovery page has been updated to include the latest observations made by the search for binary pulsars in Arecibo radio data. In total there are now 53 re-observations of 34 different radio pulsars, including 10 re-observations of 3 different milli-second pulsars. Thanks to all participating volunteers!

I'm back in Leiden and the Dutch Power Cows broke through the 25M credit boundary! Happy new year all, keep on crunching. As of this month a new application is being developed to simulate phonon effects on the dissociation of hydrogen on copper. More info will follow!

We had a problem with the database, which caused the outage. I'm trying to get more information about what happened.

I think I finally fixed the problem with the user of the day not updating, as well as a few other scripts.

Jeff17 found a 57 digit prime factor for the XYYXF number 11063+63110. This is his 8. factor and our 3. in the 2010 top 10 list.

After a few weeks of testing the deployment of the ATI application through BOINC it appears as most of the kinks have been worked out. Milkyway@Home would like to thank Cluster Physik for the development of the application and the many volunteers that assisted in reporting issues. Currently the application is available for Windows 32/64 bit and requires an ATI GPU with double precision capabilities. Milkyway@Home would also like to thank Advanced Micro Devices (AMD) for their generous donation of hardware.

I've increased the WU deadline to 8 days (up from 5). Let me know if this worked. We've been letting our searches run a bit longer now because we're trying to get more accurate results, and we've also increased the WU size so some CPUs are having problems keeping up. Because of this I think it was a good time to increase the deadline. This might also help our project play a little nicer with other ones. Let me know how it works.

Well, it looks like our old news couldn't make the transition to the new software. Hopefully it won't be missed too much. I think we've gotten most of the server problems ironed out, so let me know how things are working.

Well, I tried to run the script to update the news forum, and it ended up crashing halfway through so we have a lot of REALLY old news :) I'm going to try and fix this. --Travis

The IBM East Europe / Asia Ltd. has expressed its appreciation to the Laboratory of Parallel and Distributed Systems for their significant contribution in the introducing of the HPC-Grid system in Kazakhstan which is built on the SZTAKI P-GRADE Grid Portal, the systems of Desktop Grid and on the IBM\'s High Performance Cluster.

New Workunits: the calculation of similarities and features of new sequences, that were imported from protein databases into SIMAP until the end of December, will start in the evening (UTC) of January 7.

We needed to confirm a few of our observations in Fokker-Planck simulations, so we released more FP work units just now. This may be repeated as needed, so don't be too surprised to see FP work units on your machines every now and then.

We are done with the Fokker-Planck simulations, so all remaining work units have been cancelled. The main aqua application will again run on CPUs with two and more cores. The implication is that currently there are no work units for single-core CPUs, but this can change at anytime, so please leave your single-core boxes attached to AQUA@home. Thank you.

Voting is finished and we are pleased to announce the winner of the 5th Year Anniversary Video Contest!

We will display the voting results shortly after voting ends. Thank you. *Note - the original post was accidentally deleted.

The Arecibo Binary Pulsar search is undergoing a major transition. We expect clients to not get ABP1 tasks for a while, then, if all goes well, tasks for a new application called ABP2. Read more about this here.

With the recent server upgrade Milkyway@Home now has the ability to deploy the ATI Application through BOINC. Please watch this forum post for the latest information.

A new AP25 (Arithmetic Progression of 25 primes) has been found. It is only the 9th discovered. The finder is Dan Swearingen (endearingswan) of the United States.The AP25 progression is written as 24715375237181843+19071018*23#*n for n=0..24. It was found by an Intel Pentium 4 @ 3.00GHz running 32 bit Windows XP Professional. For more details on this find and the AP26 search, please see this forum post.

The server will be down from 5pm GMT on the 8th of January and should be back up and running by 11am on 11th of January. Sorry for the interruption there will be no power in the department over the weekend.

I think the preferences are really working now. Let me know how it goes.

I've tried changing some of the web settings to get the preferences working again. Let me know if this helped anything.

This year has been exciting, we are in the last phase of testing our docking algorithms, we have now complete results for HIV1 and Trypsin, we are running p38alpha and after that we will start a crossdocking phase. Thank you to all our volunteers and happy New Year
