2020-05-27: LHC@Home, Server outage Wednesday

Due to a failure of a database storage system, a number of database services at CERN failed on Wednesday afternoon. The LHC@home servers were affected as well, as the BOINC database was unavailable and requests timed out.

Sorry for the trouble and happy crunching!

2020-05-23: NumberFields@home, Moving to fixed credit

I have replaced CreditNew (or CreditScrew as some like to call it) with a fixed credit system.

The fixed value is based on the average runtime from many samples from a single machine in a well controlled environment (one of my own computers). Obviously, the fixed value will change with each batch, since each batch has a different average runtime.

This should be a pretty fair system, especially after a host has processed enough WUs for the average to kick in. The main downside is the potential for cherry pickers - hopefully there won't be too many of them.

2020-05-22: SETI@Home, External design review

We met with a group of outside experts to review some of our back-end algorithms. It was a productive meeting.

2020-05-21: MindModeling@Home, Outage on 2020 May 21

I'm sorry to report that we had a major outage this morning. I was able to get most things working again this morning around 1600 UTC. I'm sorry for the disruption this has caused!

Given the recent underlying hardware issues, I will likely have to take the system down for major maintenance in the near future. I will post on the forum to give notice.

Thank you for your patience!

2020-05-21: GPUGRID, More tasks: MDAD*

I'm filling up the task queue again- - these are called MDAD and suffix.
Happy crunching!


2020-05-20: GPUGRID, HTTPS

Now that the server is unloaded I'm trying to complete the switch to https. Please check if WUs up/download as usual (although I know that there are very few WUs).

2020-05-19: WEP-M+2 Project, 12-digit factor of P2203 has now been found by the project...

...240903 times - still no sign of any larger factors

2020-05-17: iThena, New Form [Info Form] - hosts information

I implemented a new form.
This form is available after logging in at the host list address:

Location of the link to the form ("Info Form"):

Template form:

All fields in this form are optional.
There is no requirement to complete these fields.

2020-05-17: SRBase, server outage / db crash again

The windows update has automatically restarted the PC in the night (was disabled), the database crashed. My 2 big backups of the VM are also corrupt including the last backups of the database. Unfortunately mysqdumper cannot import the correct numbers of tables so I used phpmyadmin with success, the last backup was from 13th so we have lost 4 days (not the reported work). I had no hope to reactivate the project but I did.

Pls stop all your old WUs. I will give credit for all the lost work. If you have registered in the last 4 days and your account is not recognized pls reregister.

I must remove all the current work and recheck all bases which results are missing. Also the TF work need to be resetup (not all I think).

Hard times, shit happens especially Windows10

2020-05-16: RakeSearch, Results of the first half of the May 2020!

Dear participants!

Two more weeks were gone and we are summing up the results of the first half of the May! 87833 were completed and computers of 176 participants found the results with the high degree of orthogonality. As usual, each of this participants receives a badge - with creeping bellflower for this May! (This badge was made by nice photograph of Fred P

2020-05-16: SRBase, planned server outage tomorrow

Another postponed update need to be installed tomorrow. The server will not be available in this time.

2020-05-16: iThena, iThena PERF version 1.03 - platforms windows_intelx86 and x86_64-pc-linux-gnu

I added iThena PERF application version 1.03 for platforms windows_intelx86 and x86_64-pc-linux-gnu.

The application for Windows requires Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019.

Theoretically, the problem with "freezing" should disappear in this version of the application.

Please inform me about possible problems ;)

2020-05-15: BOINC, Einstein@Home video

The Einstein@Home project has released a video describing their search for continuous gravitational waves.

2020-05-15: GPUGRID, Summary of the MDAD effort

So, the huge MDAD batch that we sent at the end of January just finished crunching. That was by far the largest continuous load we placed on Gpugrid, so thanks everybody!

I will be sending more continuation workunits, but it will take some time to arrange the details. For the time being, take it as a deserved break :)

The objective of the batch was a large-scale exploration of the protein landscape. Its accumulated 25 ms of sampling will be useful for biomedical protein modeling at large (we'll provide more details in due time).

Crunching the whole set was a technical challenge per se. Volunteered power has grown a lot during the project. This may have been motivated by (1) the continuous availability of so many workunits; (2) shutting down SETI server; (3) the lockdown; (4) the notoriety of distributed computing for fighting COVID-19. This placed additional strain on the server, but in the end the mammoth task was completed - and we want more :)


2020-05-15: BOINC, World Community Grid launches COVID-19 research project

The OpenPandemics - COVID-19 project aims to accelerate the search for treatments for the disease caused by the SARS-CoV2 virus. Learn more about the project here.

2020-05-14: World Community Grid, Help Stop COVID-19 and Future Pandemics in Their Tracks?

The OpenPandemics - COVID-19 project helps researchers at Scripps Research look for potential COVID-19 treatments. But that's just the beginning for our newest project, and we need your help.

2020-05-11: World Community Grid, The Microbiome Immunity Project Must Go On!

Research in the time of a pandemic is more important than ever. Here?s how the Microbiome Immunity Project team is making continued progress while working from home.

2020-05-11: NumberFields@home, Not enough available work

There are reports of not enough available WUs.

I believe this is caused by the "accelerated retries" mechanism. So I have temporarily disabled this feature.

This mechanism normally works very well, but I think the current Pentathlon is pushing it to the limit. In particular, if too many WUs are being aborted, then the work queue is flooded with "failed" jobs that now have a higher priority, and these jobs require a "reliable host". To make things worse, any host aborting too many jobs is flagged as unreliable, so won't be given any of these tasks.

2020-05-10: PrimeGrid, SR5 Mega Prime!

On 1 May 2020, 04:01:08 UTC, PrimeGrid?s Sierpinski/Riesel Base 5 Problem project eliminated k=118568 by finding the mega prime:


The prime is 2,175,248 digits long and enters Chris Caldwell's ?The Largest Known Primes Database? ranked 70th overall and is the largest known base 5 prime. 30 k?s now remain in the Sierpinski Base 5 problem.

The discovery was made by Honza Cholt (Honza) of the Czech Republic using an Intel(R) Core(TM) i7-9700K CPU @ 3.60GHz with 32GB RAM, running Microsoft Windows 10 Professional x64 Edition. This computer took about 49 minutes to complete the primality test using LLR. Honza Cholt is a member of Czech National Team.

The prime was verified on 2 May 2020, 09:00:41 UTC by Tom Murphy VII (brighterorange) of the United States using an AMD Ryzen Threadripper 2990WX 32-Core Processor with 128GB RAM, running Microsoft Windows 10 Professional x64 Edition. This computer took about 1 day, 1 hour, 55 minutes to complete the primality test using LLR.

For more details, please see the official announcement.

2020-05-09: iThena, Maintenance interruption in access to the system

Tonight (May 9th, 2020) at night (UTC) I will be modifying the iThena database.

The project can be offline for 1-2 hours.

2020-04-29: BOINC, BOINC workshop cancelled

The 2020 BOINC workshop, scheduled for 7-10 September, has been cancelled because of the COVID-19 pandemic.

2020-04-28: RALPH@Home, New application version 4.17 graphics has issues.

A new application was released that includes improvements to the database extraction method. Unfortunately, there is an issue with the graphics application in this update. We are working on a fix.

2020-04-28: GPUGRID, Project resumed

Disk occupation went down a bit, so I am un-suspending.

2020-04-27: GPUGRID, Suspending project

I'm temporarily suspending the project to give time to empty the disk.

2020-04-26: SETI@Home, Nebula progress and non-progress

The last data has been sent out, but our work on Nebula - the final phase of data analysis - is picking up steam. However, not all ideas are good ideas. Read about Multiplet scoring: back to the drawing board.

2020-04-25: Asteroids@home, New CUDA102 application was released

Today we released a new CUDA102 application v102.14 for both Windows & Linux.
A bug was fixed where application causes 100% utilisation of whole CPU core (thread in hyperthreaded CPUs)

2020-04-24: T.Brada Experimental Grid, Plan for SPT subproject

For processing of SPT results I found a partner that will help me write a export script to OEIS, and he is working... And while he is working I forgot a bit that I have a project, sorry. I was excited to have my name in OEIS, but it is not yet ready and the excitement is fading.
The previous batch, using the new file upload handler ran out, and it is much smoother. I submitted new batch 70 that goes up to 5e17. See, this new SSD and FUH allows me to have larger batches. And after that, I will submit batch for 5e17-6e17. You might notice that we already did that range, but that was with old version, which only looked for symmetric prime tuples and was slower.
Regarding the padls total (tot5) subproject, it is still running, but I throttled it to only few active tasks to not waste power. There are some ideas to improve it.
However, I am working on the Lua / compile-on-target application.
Have a Great day everybody and stop pretending and blocking yourself.

2020-04-24: LHC@Home, CERN and COVID-19

Like many organisations, CERN is also affected by the COVID-19 pandemic. Researchers in the CERN community are trying to help out in different ways, as explained on this web page.

As part of this effort to fight COVID-19, we also contribute computing power to Folding@home and Rosetta@home from temporarily available servers that were about to be decommissioned.

During periods like this with little work from LHC@home, we also encourage you to participate in other BOINC projects such as Rosetta@home and contribute to the global fight of the pandemic.

Many thanks for your contributions to LHC@home and continued happy crunching!

With the best of wishes of good health for your and your families from the LHC@home team.

2020-04-20: GoofyxGrid@Home NCI, New works generators

In next 7-10 days i would like to make some change in generators so it could be problem with getting new WU.
Acctuall generators are making too much IOPS on disk on my serwer and making it's very unstable and less performance that they could be.
One generator (and i have four of them working 24/7 ) can generate 300-350 (or even have peak to 450-500) IOPS and killing server
