The Generalized Fermat Prime Search is now out of beta and open to all users. An Nvidia GPU with double precision floating point hardware is required for this project. Also, MacIntel CPU's are supported at the current N=262144 (b^2^18).
A wealth of discussion has been gathered during the beta phase. For any issues or questions, please see the Generalized Fermat Prime Search forum.
This search will eventually reach N=4194304 (b^2^22) which, if successful, has the potential of discovering the world's largest known prime number. Current testing times at N=262144 are ~1 hr for fast GPU's and ~7 hrs for fast MacIntel CPU's.
Best of Luck to everyone!
We have recently started a limited doublecheck effort for The Riesel Problem and this has very quickly yielded a prime, which means that the results that we obtained from Riesel Sieve project cannot be trusted 100%. Therefore we have decided to run a full doublecheck effort.
We would like to quickly go through the doublecheck ranges and resume our original search, so we would like to ask you to consider redirecting any resources you may have available to The Riesel Problem (TRP) subproject. You can do that by visiting project preferences page.
Applications are available for Windows, Linux and Mac. 32bit applications will be sent to 64bit hosts.
Me gustaría hacer un repaso rápido del estado de Ibercivis a Febrero de 2012, últimas noticias, etc.
.- Criticalidad: Nuestros amigos mexicanos nos comentan que los datos obtenidos en Ibercivis han sido satisfactorios y útiles. Han sido utilizados para escribir una tesis y el artículo Conductance statistics for the power-law banded random matrix model. Esperan volver a enviar wus en un futuro próximo.
.- Sanidad: Unas 500.000 wus están siendo enviadas a vuestros ordenadores, por cortesía de Julio. Decir que estas wus tienen una duración media de 3 horas,mas largas que en tandas anteriores y una caducidad de 4 días.
.- Mr.Wilson: Estamos tomando un pequeño descanso para analizar los resultados, os puedo comentar que nuestro rango de búsqueda previsto en esta primera fase es desde 5x10^8 hasta 4.3*10^9, del que hemos realizado el intervalo 5*10^8 hasta 3*10^9. Además Danilo Nitsche, estudiante de phd de física teórica aportó una mejora en nuestro código triplicando la velocidad inicial.
Por último me gustaría dar la bienvenida al usuario kzgunea, que con sus casi 1600 ordenadores conectados ha supuesto un fuerte impulso a nuestra capacidad de cálculo.
Muchas gracias a todos por vuestra inestimable colaboración.
On 2 Feb 2012, 21:30:55 UTC, PrimeGrid’s The Riesel Problem project eliminated k=162941 by finding the prime: 162941*2^993718-1
The prime is 299,145 digits long and will enter Chris Caldwell's The Largest Known Primes Database ranked 1536th overall. This prime was found while exploring a suspected gap in a previously searched range. This is PrimeGrid's 8th elimination. 56 k's now remain.
The discovery was made by Dmitry Domanov (unconnected) of Russia using an Intel Xeon @ 3.60GHz with 2 GB RAM running Windows Server 2003 Enterprise x86. This computer took just over 1 hour 5 minutes to complete the primality test using LLR. Dmitry is a member of Team Russia.
For more details, please see the official announcement.
Dear all,
We are very happy to announce that we have released today a new virtual machine (cernvm_2.5.1-3-1).
This new version has several improvements at the low level that will help to improve the number of returned successful jobs.
You will get the new virtual machine when all the jobs with the previous VM version have been processed.
Best regards,
The team.
With the new server software release installed in the end of January we experienced that many more workunits are sent to the hosts as usual. We are currently investigating this, seems that the project contiguration settings are differently interpreted by the new software. To avoid total overload of hosts by SIMAP results, we have reduced the daily maximal number of results per host to 300. We will check and adapt this limit during the next days continuously.
Best regards
Thomas
Einstein@Home volunteers have discovered three new radio pulsars in Arecibo PALFA data -- the eighth, ninth and tenth new radio pulsars found by Einstein@Home volunteers in this data set! Congratulations to:
Peter van der Spoel, Utrecht, the Netherlands
Edvin Grabar, Pula, Croatia
Shadowfax, Baltimore, Maryland, USA
Cauche Nathanael
John-Luke Peck, TerraPower & Intellectual Ventures, Seattle, Washington, USA
Mark Henderson, Morristown, Tennessee, USA
Further details about these newly-discovered pulsars can be found on this web page, and will be published in due course.

As I am in the final months of my phd thesis, I didn't have (and won't have) enough time in the coming weeks to take care of POEM@HOME. Therefore there will be some new faces in the coming weeks on the POEM@HOME message boards (and behind the scenes). I really had a blast working with POEM@HOME and will still be available for consulting for the new team. Thank you everybody for all this help, as without you my phd thesis wouldn't have been possible. - Timo Strunk

Da ich in den letzten Zügen meiner Doktorarbeit stecke, hatte ich nicht genug Zeit um mich um POEM@HOME zu kümmern (und werde auch leider nicht genug haben). Daher werde ich meine Arbeit nun an ein neues Team übergeben, welche sich demnächst auf den Message Boards vorstellen werden. Ich werde dem Team natürlich auch weiterhin bei Problemen helfen. Danke an alle hier für eure immense Arbeit. Ohne euch wäre die ganze Forschung und auch meine Doktorabeit keinesfalls möglich gewesen. - Timo Strunk
Dear all,
During this week you are going to experience some minor problems with the web application, as we are deploying it in your VMs. While the deployment is done, you will get the warning message from the web application, saying that your browser does not support HTML5 and Javascript, but giving you access to the figures and logs via two links.
This warning message will be removed, once we have finally done the deployment.
Sorry for the inconveniences.
Best regards,
The team.
UPDATE: The new web application has been deployed in our servers. In one hour you should be able to reboot the VM if you want to see the new application or wait until your WU finishes. The next WU will have the updated code.
The workunits for the about 410.000 new protein sequences (for the February release of SIMAP) will be available from Wed, Feb 1. We estimate that the batch for February will need about two weeks of work.
Best,
Thomas
