Server outage resolved  |
I am sorry for server outages which was happening recently. There were several factors which often caused lack of free space and some services crashed and I had to do an emergency shutdown on Saturday in order to fix everything so I couldn't inform you about it except for Twitter. There is still a hardware problem with one of servers which I have to fix but the server is not being used now so project should be stable now.

| New Runs for MilkyWay@home Nbody Simulations (07/07/2020) |
Hey all,
The last set of N-body runs we set up started converging to compact progenitors due to an overly restrictive data histogram. We have fixed the data histogram and placed new runs up on the server:
-de_nbody_07_07_2020_v176_40k__data__1
-de_nbody_07_07_2020_v176_40k__data__2
-de_nbody_07_07_2020_v176_40k__data__3
Please let us know if these runs cause any problems, and thank you all for your support.

| CMS job rundown |
We need to do some tests of a patch to fix a bug that's been plaguing us for some time. To this end, I am letting the job queues drain, so there will be an absence of CMS jobs -- perhaps as soon as tomorrow morning, depending on how we continue to recover from today's Oracle quota problem.
So, be prepared to set No New Tasks as soon as you see any sign of lack of jobs -- or sooner if you prefer.
I don't know how long the testing will take, there are many factors at work (if the BOINC server sees that there are no jobs available, it will stop sending tasks; that will mean it takes longer for each test batch to be recognised and start serving jobs).

| New Separation Runs 6/19/2020 |
Hello Everyone,
I have put up the following separation runs:
de_modfit_80_bundle4_4s_south4s_bgset_3
de_modfit_81_bundle4_4s_south4s_bgset_3
de_modfit_82_bundle4_4s_south4s_bgset_3
de_modfit_83_bundle4_4s_south4s_bgset_3
de_modfit_84_bundle4_4s_south4s_bgset_3
de_modfit_85_bundle4_4s_south4s_bgset_3
de_modfit_86_bundle4_4s_south4s_bgset_3
And I have taken down the following separation runs:
de_modfit_80_bundle4_4s_south4s_bgset_2
de_modfit_81_bundle4_4s_south4s_bgset_2
de_modfit_82_bundle4_4s_south4s_bgset_2
de_modfit_83_bundle4_4s_south4s_bgset_2
de_modfit_86_bundle4_4s_south4s_bgset_2
de_modfit_14_bundle5_testing_4s3f_1
de_modfit_14_bundle5_testing_4s3f_2
de_modfit_14_bundle5_testing_4s3f_3
de_modfit_14_bundle5_testing_3s4f_1
de_modfit_14_bundle5_testing_3s4f_2
de_modfit_14_bundle5_testing_3s4f_3
The new runs are copies of the previous bgset_2 runs, in order to verify our results. Since the stripe 84 and 85 runs in the last set went a bit wonky after a couple weeks, I expect the same to happen here. I will keep a close watch on these forums, and when people begin to report errors from the runs on those stripes, I will promptly take them down. The errors that people are reporting on the bgset_2 runs should stop in the next couple days as the old runs all finish trickling in.
All of the testing runs have come down (there may be more in the future).
Thank you all for your continued support with this project. Stay safe (and sane) in these strange times.
Best,
Tom

| Downtime Saturday |
The database underlying LHC@home will be down on Saturday 27th of June due to an upgrade of a DB storage rack.
Hence LHC@home BOINC services will be unavailable for a good part of the day. (Est 5:30-12:30 UTC)
So your BOINC client connections to our servers are likely to fail on Saturday.
Thanks and happy crunching!

| Thank you for R10 search! |
Dear participants, a partial search R10 is over and we have placed links to its results on About RakeSearch page.
Also, we want to say great thank you to all the project participants! To everyone who returned at least one correct result, we gave out a special badge with a bumblebee - as one of the symbols of distributed computing, when everyone is doing something themselves, helping the common cause.
Is this the final? May be not! Who knows?
P.S. And some statistics! Project performance during R10 search expressed in CPU time (in days) per day or number of active threads!

| GFN-524288 Find! |
|
On 29 May 2020, 07:52:25 UTC, PrimeGrid's Generalized Fermat Prime Search found the Mega Prime:
3638450^524288+1
The prime is 3,439,810 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 3rd for Generalized Fermat primes and 35th overall.
The discovery was made by Wolfgang Schwieger (DeleteNull)of Germany using a GeForce RTX 2070 in an AMD Ryzen 7 3700X 8-Core Processor with 16GB RAM, running Linux openSUSE . This GPU took about 31 minutes to complete the probable prime (PRP) test using GeneferOCL5. Wolfgang Schwieger is a member of the SETI.Germany Team.
The PRP was verified on 29 May 2020, 08:23:51 UTC by Greg Miller (Olgar) of the United States using a gfx1010 in an AMD FX-8370 Eight-Core Processor with 16GB RAM, running Microsoft Windows 10 Professional x64 Edition. This computer took about 1 hour, 3 minutes to complete the probable prime (PRP) test using GeneferOCL5. Greg Miller is a member of the USA Team.
The PRP was confirmed prime by an Intel(R) Xeon(R) CPU E3-1240 v6 @ 3.70GHz with 4GB RAM, running Linux Debian . This computer took about 1 day, 19 hours, 22 minutes to complete the primality test using LLR.
For more details, please see the official announcement.

| [all] status update |
Is Citizen's Science Grid officially dead?
If you read Travis's profile here:
http://www.se.rit.edu/~travis/index.php
His energy is currently directed on other projects. It would seem this project is shelved and may never be awakened (depending on the direction Travis takes with his career).
personally I wish Travis all the best with his future endeavours.

| Recovering lost credits / Recuperando los créditos perdidos |
Dear volunteers,
First of all, I hope that all of you and those close to you are well in this global pandemic.
This week is the anniversary of one of the hardest moments of this project. Three years ago, during a database update, it was corrupted. With this failure we detected that the backup system of the data base was not working as it should and we were only able to restore a 6-months-old backup. All this situation coincided just at the moment in which we stopped having a person dedicated full time to the project, which supposed an added difficulty.
The results sent by the volunteers were saved in another system and only the tasks in progress were affected.
The main loss of information was the credits obtained by the different volunteers. At that time we were able to recover a large part of them, but all the accounts created between January and June were lost.
Your support and understanding during those days was enormous. However, as I told you at the time, being able to return the credits to you was an important issue: it is the only way we have to thank you for all the support for the project.
Since then, several of you have asked me if we could recover the credits from those accounts, and I didn't want to let it go any further. It was not an easy job because we had the credit information but not a system to connect them with the new accounts you were creating. Thanks to the existence of Boincstats.com and the BOINC cross project identifier, part of you will be able to recover your credits. I have been able to find almost 300 of those accounts on Boincstats.com, and in the next few days, through Boincstats.com, I will send you a link to recover lost credits. You will receive a personalized URL that will add the lost credit to your user and will correct the date since you are collaborating with us. I will send the messages in several days so that Boincstats.com does not exceed the limit of messages it can send. I want to publicly thank Will for allowing me to use his platform for all this messages. I will notify you when all are sent.
If you don't have an account on Boincstats, you can create it and associate it with the BOINC projects you collaborate on. I will periodically search for new users to whom we can return credits.
If you have any idea to associate your old accounts with the current ones, do not hesitate to contact me, we will find how to prepare it.
This is the first step to gradually start up this project again. You are an incredible community that we do not want to miss. Unfortunately, we cant afford to hire someone full time for the project so we will go very slowly. We have tried several times to obtain founds for the project and we have had good evaluations, but not enough to get them. We will continue working on it, but until we get it, we will go slowly.
Thank you very much, you have me at your disposal and I hope that, little by little, you will be receiving more messages from me.
Greetings,
Jesus.

Estimados voluntarios:
Lo primero de todo espero que todos vosotros y vuestras personas cercanas estéis bien en esta pandemia mundial.
Esta semana es el aniversario de uno de los momentos más duros de este proyecto. Hace tres años, durante una actualización de la base de datos, ésta se corrompió. Con este fallo nos dimos cuenta de que el sistema de copia de la base de datos no funcionaba como debería y sólo pudimos restablecer una copia con 6 meses de antigüedad. Toda esta situación coincidió justo en el momento en el que dejamos de tener una persona dedicada a tiempo completo al proyecto, lo que supuso una dificultad añadida.
Los resultados calculados por los voluntarios se guardaban en otro sistema y sólo se vieron afectadas las tareas que estaban en marcha.
La principal pérdida de información fueron los créditos obtenidos por los diferentes usuario. En aquel momento pudimos recuperar gran parte de ellos, pero todas las cuentas creadas entre enero y junio se perdieron.
Vuestro apoyo y comprensión durante aquellos días fue enorme. No obstante, como os dije en aquel momento, para mí el poder devolveros los créditos era un tema importante: es la única forma que tenemos de agradeceros todo el apoyo al proyecto.
Sois varios los que desde entonces me habéis preguntado si podríamos recuperar los créditos de esas cuentas, y no quería dejarlo pasar más. No era un trabajo fácil porque teníamos la información de los créditos pero no un sistema para conectarlos con las nuevas cuentas que estabais creando. Gracias a la existencia de Boincstats.com y de un identificador de BOINC interproyectos, parte de vosotros podrá recuperar sus créditos. He podido encontrar casi 300 de esas cuentas en Boincstats.com, y en los próximos días, a través de Boincstats.com, os enviaré un enlace para poder recuperar los créditos perdidos. Recibiréis una URL personalizada que al entrar en ella con vuestro usuario de DENIS, os añadirá el crédito perdido y corregirá la fecha desde la que estáis colaborando con nosotros. Mandaré los mensajes en varios días para que Boincstats.com no supere el límite de mensajes que puede enviar. Quiero agradecer públicamente a Will, que me permita utilizar su plataforma para un envío masivo de mensajes. Cuando todos estén enviados os avisaré.
Si no tenéis cuenta en Boincstats, podéis crearla y asociarla a los proyectos en los que colaboréis. Periódicamente buscaré si hay nuevo usuarios a los que podamos devolver los créditos.
Si se os ocurre algún otro sistema para asociar vuestras antiguas cuentas con las actuales, no dudéis en contactarme, buscaré la forma de ponerlo en marcha.
Este es el primer paso para ir poniendo poco a poco en marcha de nuevo este proyecto. Sois una comunidad increíble y no se os puede desaprovechar. Por desgracia, no podemos contar con alguien a tiempo completo por lo que iremos muy despacio. Hemos intentado varias veces obtener financiación para el proyecto y hemos tenido buenas evaluaciones, pero no lo suficiente para llegar a ser financiados. Seguiremos trabajando en ello, pero hasta que lo consigamos, iremos despacio.
Muchas gracias, me tenéis a vuestra disposición y espero que poco a poco vayáis recibiendo más mensajes míos.
Un saludo,
Jesús.

| Should the fixed credits be higher? |
I have had a couple people mention that the fixed credits should be higher. I tried to set the credits to be in line with the cobblestone definition, but it's possible I missed the mark.
I will wait for feedback before making any changes. Please share your credit opinions.

| New Runs for MilkyWay@home Nbody Simulations (06/08/2020) |
Hey everyone,
We realized that the comparison histogram in the last set of runs contained incorrect data. As such we have replaced the last set of runs on 05/30/2020 with the following runs in their place:
-de_nbody_06_08_2020_v176_40k__data__1
-de_nbody_06_08_2020_v176_40k__data__2
-de_nbody_06_08_2020_v176_40k__data__3
We apologize for any inconvenience,
-Eric

Hello,
Today is my last day working on MindModeling. Taking over as primary devop is Olivia, who has worked with me for the past year. This won't affect day to day operations, beyond who is responding to you all and who is working behind the scenes.
I know we are currently having several issues -- with Lisp jobs on Windows in particular -- that I feel bad for leaving to her, but I know the site is in good hands. Please be patient with her when there are issues. It's a thankless job keeping the lights on, and work moving through the system. :P
Happy crunching!
Josh

| The last bunch of tasks were generated |
Dear folks!
A few hours ago we generate the last bunch of tasks R10 search. The search is close to completion, after which its results will be processed and uploaded for public access. Thank you for donation of CPU Time, attention for the project and participation! The volunteer distributed computing is amazing feature of out time!
Thank you!
