Hello everyone,
We will be running server maintenance on June 1st, 2023 at 11:30 AM EDT.
Maintenance should be done by the end of the day.
An announcement will be made on this thread when maintenance is over.
Thanks,
Kevin
The NFS@Home project will be offline much of the day on Saturday, May 27, due to campus IT maintenance and testing. All access should be restored by 8pm PDT.

User Favebook found a 77-digit prime factor of an Homogeneous Cunningham number using ECM. This is by far the largest factor found anywhere by ECM this year, and is the 4th largest ever. Very exciting!This was a very lucky find (about a 1 in 28.3 million chance for a single curve).
Hello everyone,
RPI is conducting their annual CII power maintenance between May 8th and May 10th. As a precaution, we will need to shutdown the server during this time.
We will have the server back up and running as soon as possible.
Thank you,
Kevin
Dear volunteers,
We update you on the status of the project and how the simulations are going. In recent weeks the search algorithm has been improving the model very little. This indicates us that the optimization is close to be finished. Once this is complete we will pass to the validation phase which we will be done outside of DENIS (DENIS is not yet prepare for the required simulations).
The improvement obtained is very considerable (you can see the graph with the evolution of the error…
Dear volunteers,
Allow me a brief message to update you on how the results are going after 15 more days of simulation.
5 iterations of the algorithm have already been completed. Of the 100 markers that we are using, 89 have already been achieved in the normal range (initially only 77 were). On the other hand, the distance between the average experimental behavior and the model has been reduced by 56.84%.
Several parameters of the algorithm indicate that there is still room for improvement.
We…
Hello everyone,
The following are the new runs for N-Body:
de_nbody_02_27_2023_v182_pal5__data__1
de_nbody_02_27_2023_v182_pal5__data__2
de_nbody_02_27_2023_v182_pal5__data__3
These are our first runs of Palomar 5 with data from SDSS DR17.
Please let me know if there are any issues with these new runs.
Thanks,
Kevin
Dear volunteers,
The Science Commons Initiative has created a store to sell merchandising from BOINC projects to help fund the development of BOINC and the projects as well.
We have given them permission so you can find products with the DENIS logo. 50% of the profits on these products will go to develop BOINC and the other 50% will be donated to support DENIS.
You can see them at https://www.redbubble.com/es/shop/ap/138889661
However, if you have any questions about the products or anything…
Dear volunteers,
We have good news! After processing the results of the first iteration, we have found a combination of model parameters that improves the behavior of the model compared to the initial one. In the original version, of the 100 markers that we are using, 77 were in the experimental range: now there are 80. On the other hand, the distance between the model and the average experimental behavior has been reduced by almost 30%.
The values of several of the parameters that have been…
Dear volunteers,
I have both good and bad news to share with you regarding our recent progress. First, the good news: thanks to the results you've sent in, we have been able to identify the problem with the marker and gain a better understanding of what was happening. Additionally, it turns out that we won't need to increase the number of simulations per iteration, which is good news (for us).
However, there is also some bad news to report. We've discovered that the behavior of the model with…
Dear volunteers:
As we had indicated in previous messages, we had to stop fitting the model because there was an experiment that we could not fit well. After analyzing our results, we believe that one of the limiting factors could be in the number of simulations we do to fit the behavior of the model in the experiment. Therefore, before continuing with the model fit, we are going to do a new test to study this in detail. We just put in new simulations to help us analyze this experiment to see…
Dear volunteers,
Due to work overload in other projects we will not be able to restart sending tasks until January. Sorry that this break is taking longer than expected, we want to get back as soon as possible.
All the best,
Jesus.
====================
Estimados voluntarios:
Debido a sobrecarga de trabajo en otros proyectos no vamos a poder relanzar el envío de tareas hasta enero. Disculpad que esta pausa esté siendo más larga de lo esperada, queremos volver cuanto antes.
Un saludo,
Jesús.
Hello everyone,
Looks like the server had some issues. I rebooted the server and it seems like everything should be running as it should.
Thanks,
Kevin

Hello everyone:
First of all, excuse these days without notices from us, but the start of the course has required more time than we expected and we have not been able to be as active as we would like in the project.
We update you on how the optimization of the model is going: after 3 iterations of the algorithm, the model is gradually improving, but one of the markers is greatly limiting the improvement. We full understand why this is happening, so we need to stop and analyze it in detail…
Hey Everyone,
We've been noticing some occasional long loading times and brief connection disruptions with the server, so I'm going to take things down at noon ET tomorrow (4PM UTC) and reboot the server. It should be back up pretty quickly. Hopefully this fixes the issues we're having.
Best,
Tom
Hello everyone,
My name is Kevin Roux and I will be working with Dr. Newberg for my Ph.D thesis. I look forward to working on this project and working with you all for the next couple of years.
Best,

Hi!
Due to a review of the electrical installation of the University, DENIS@home could be temporarily out of service today between 15:00 and 20:00 CEST.
Sorry for any inconvenience it may cause.

hi,
Murphy law is always in on modality!
Last year I did not went to holiday and all was fine.
This year I takes 15 days holiday to compensate the last years, and something goes wrong!
I leaved on 6 and the day 7 I got an email notification that my weather station (that every five minutes put online the collected data), was not online (it uses the same internet connection of the server).
However when I check the station and server connectivity from the cell all was fine.
But every days/few…
