2020-02-21: SRBase, new work coming soon

All the rest of the work was cancelled except long3 (these are the last results which need to complete the batch)

2020-02-21: SRBase, server and db crash

Due a windows 10 bluescreen, cant identify yet whats causing this crashed the project database and cant be recovered. The old backup from 02.02. was resetup.

All new users or hosts after this date need to be registered again. Pls stop all the current work. I will see what I can do to rescue the old work and upload the missing files.

With this new OS I cant believe it. As long as I cant find the issue Iam lost. Trying to readout the dump file to be sure to fix this main problem.

Sorry for all the troubles.

2020-02-21: TN-Grid, World Gene Expansion Challenge 2020

The volunteers belonging to the BOINC.Italy group have organized a challenge on this project, from March 16 at 12:00 UTC up to March 23 at 12:00 UTC.

Have a look at the challenge banner here: https://www.boincitaly.org/media/kunena/attachments/6725/TN-GridCh.jpg and the boincstats announcement/chat page: https://www.boincstats.com/stats/challenge/team/chat/1072

2020-02-19: LHC@Home, CMS@Home -- ongoing problems

Sorry that the CMS@Home HTCondor server is still playing up. Again over the weekend it refused to serve jobs even though plenty were available. Together with Federica we've decided not to inject another workflow this week, to let if "fail hard" again so that she can investigate which ClassAd preferences are not being met.
So, you will probably see the number of running jobs falling, and the number of errors increasing, in the next few days. Please feel free to set No New Tasks in that case. I won't, so that there is still some pressure for jobs on the server. I've also asked Laurence if I can run the CMS@Home VM outside of BOINC, to get around the quota back-off problem.

2020-02-18: SRBase, new faster internet connection

The internet speed got an upgrade from 400/25Mbit to 1000/50Mbit. Now things should be faster.

2020-02-18: QuChemPedIA@home, NWChem long

Dear crunchers.

Thank you very much ! You are a really great help.

Initially, only two hundred "NWchem long" workunits should have been submitted for testing. Your numerous results and also the numerous failures allow us to better evaluate parameters for this new simulation. I still have to write some scripts for the new inputs, but I should be able to submit jobs soon. Don't hesitate to cancel in progress workunits (NWchem long).

Cheers,
Benoit

2020-02-17: GPUGRID, Experiment queue being filled up

There should be plenty of work in workunits of the "MDADpr4" series. It should be one of the largest efforts so far.

2020-02-15: RakeSearch, Results of the first half of the February 2020!

Dear folks!

During winter, marinated chanterelle is a delicacy in Karelia. These orange aromatic mushrooms grow in families (or constellations?) in our forests. In Russian, their name sounds like ?foxy? due to their color that gave names to both mushrooms and animals. Chanterelle - the badge of this month! Computers of 127 participants found pairs with a high degree of orthogonality in the last two weeks and we congratulate them:

2020-02-14: SRBase, In a single daily email notification issue

Pls dont use this setting, activate "In a single daily email" instead. The project sending out an email every 5min and flooding the email box, something is broken.

2020-02-13: TN-Grid, No news is good news (sometimes)

Just wanted to say that everything is going on smoothly. The server is stable, the scientists are happy with the results and are doing their analysis. Thanks all!

2020-02-12: LHC@Home, CMS@Home up again

OK, jobs are available again. Sorry for the long delay. Remember, I'm only the front-man for a larger crew, so any downstream delays percolate up to my response. Hopefully this will remain good for some time, but I still don't understand why the condor server occasionally refuses to send out jobs in a timely manner.

2020-02-10: MilkyWay@home, New Runs for MilkyWay@home N-Body (2/10/2020)

We apologize once again, but it seems we have run into another error with the last set of runs. These runs will be replaced by the following runs:
-de_nbody_02_10_2020_v176_40k__data__1
-de_nbody_02_10_2020_v176_40k__data__2
-de_nbody_02_10_2020_v176_40k__data__3

Rest assured that these errors do not affect the ability of your computers to run the milkyway_nbody application and will not cause you to lose credit. Thank you for your patience and your continued support.

2020-02-10: LHC@Home, CMS@Home accidentally shut down -- Please set No New Tasks

We need to upgrade the CMS@Home WMAgent before Thursday, so I tried to set the workflows to drain down. Unfortunately, I misunderstood the batch states and killed off most of them instead. :-(. There's one still left with about 200 jobs, so that won't last long.
Please set your CMS projects to No New Tasks to avoid getting lots of computation errors. I'll let you know when the upgrade is done and jobs are flowing again.

2020-02-08: iThena, New application, new possibilities, new problems ;)

I will soon be implementing a new application ;)
The application will be called iThena NRT.

The credit problem will be solved.

The tasks for iThena CNode will be phased out.

However, there are many problems.
Initially, iThena NRT will be available as a virtualised environment (VBox/Vmware). You will be able to start a virtual system.

Of course it will also be possible to run it locally.

In addition, the iThena NRT application will require a permanent connection to the Internet.

2020-02-08: iThena, Performance problems

There are performance problems in system operation.
Today / tomorrow I'll be reconfiguring the database.
Possible problems with system availability.

2020-02-03: QuChemPedIA@home, Molecules are coming!

Dear crunchers.

The new batches of molecules are coming! With them come the new credit system (200 credits per WU) and quorum validation. the expected runtime is 2-3 hours on a recent personal computer.

You can also see a new beta application (NWChem long) that will be used for the bigger calculations we talked about. The inputs are ready since the poll, but I still have to perform some tests. Stay tuned!

Kindly

2020-01-30: T.Brada Experimental Grid, Database Crash and Recovery

Unfortunately, the database here suffered a corruption and crashed. Fortunately, the backup was less than 24 hours old, so we did not loose much.
I am attempting to recover recent results that are lost in database from uploaded files. While this process is running, scheduler will be disabled and you may see strange numbers in the server status page. After that process is complete, you will have time to upload results in progress. The results that are definitely lost will be resent.
No other results were lost.

2020-01-30: QuChemPedIA@home, Credits and Gridcoin

Dear Crunchers,

Yesterday, I had to suspend an account for two weeks and remove credits, for obvious credit cheating investigations. I'm quite annoyed that instead of doing science, I have to deal with this kind of behavior. We're small and we're short on time and it doesn't help scientific research...
EDIT : after investigations and fruitful exchanges, the problem has been identified and I'm sorry to have been a bit rough with this user.

The current credit system is too easy to fool, so I'm going to move to something simpler, robust and more generous on average: fixed credits. For short tasks (such as od9), I'm going to award 200 credits. This change requires draining the task queue. At that time, I will submit new tasks. These new tasks will be the opportunity to deploy the new code with checkpoints, system signals and affinity management for large systems (>32 cores). Some errors are to be expected, I can't test everything.

The last point concerns the requests for Gridcoin. I've been asked by the developers and by some of you. I am not against this possibility, but three points do not allow for the moment to be whitelisted. First, I can't guarantee to always have tasks waiting to be calculated. Secondly, the incentive to cheat will increase and I find that increasing the quorum is a waste of resources. Thirdly, I'm struggling with the server to keep it up. The upcoming arrival of larger molecules should settle the first point. For the second point, we are thinking about a validation by analyzing the result. I have already made many optimizations for the third point, at the moment it's much better.

2020-01-28: QuChemPedIA@home, New Linux app and new WU

Dear Crunchers,

I have written a new version of the application for Linux (0.12), which is deployed in beta. The checkpoints have been added, but the display of the task progress is not correct. Don't worry, the computation is back to where it was. Moreover, I've added an adhoc management of system signals, to interrupt and resume tasks correctly. WARNING, this code is in beta and has a very high chance to fail. Please only use it if you want to monitor what is going on and help debugging. if the code does not cause a problem, it will quickly become the new reference code (ie. not in beta).

For Mac and Windows users, I am currently looking for workarounds for problems with Virtual Box.

I'll soon be putting short tasks for small molecules in the od9 series. Stay tuned !

kindly,
Benoit

2020-01-25: PrimeGrid, World Record Fermat Divisor Found!

On 22 January 2020, 15:00:58 UTC, PrimeGrid's Fermat Divisor Search found the Mega Prime:

13*2^5523860+1 Divides F(5523858)

The prime is 1,662,849 digits long and will enter Chris Caldwell's The Largest Known Primes Database ranked 115th overall. This is a world record for prime Fermat divisors, and it is also ranked 4th for ?weighted? prime Fermat divisors.

The discovery was made by Scott Brown (Scott Brown) of the United States using an Intel(R) Core(TM) i7-4790 CPU @ 3.60GHz with 16GB RAM, running Microsoft Windows 10 Core x64 Edition. This computer took about 39 minutes to complete the primality test using multithreaded LLR. Scott is a member of the Aggie The Pew team.

The prime was verified on 22 January 2020, 15:11:39 UTC by Stefan Larsson (288larsson) of Sweden using an Intel(R) Core(TM) i9-9900K CPU @ 3.60GHz with 8GB RAM, running Microsoft Windows 10 Core x64 Edition. This computer took about 46 minutes to complete the primality test using multithreaded LLR. Stefan is a member of the Sicituradastra. team.

For more details, please see the official announcement.

2020-01-23: LHC@Home, Server outage - uploads failing

Due to a network problem in the CERN computer centre early Thursday morning, our BOINC servers have lost access to a storage cluster. Hence uploads are failing and access to web pages as well. Hopefully this should be fixed soon.

2020-01-22: PrimeGrid, Another GFN-262144 Find!!

On 21 January 2020, 00:49:54 UTC, PrimeGrid's Generalized Fermat Prime Search found the Mega Prime:

9450844^262144+1

The prime is 1,828,578 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 15th for Generalized Fermat primes and 85th overall.

The discovery was made by Jacob Eikelenboom (Eikelenboom) of The Netherlands using an NVIDIA GeForce RTX 2060 in an Intel(R) Core(TM) i7-9700F CPU @ 3.00GHz with 16GB RAM, running Microsoft Windows 10 Core x64 Edition. This GPU took about 18 minutes to complete the probable prime (PRP) test using GeneferOCL2.

The prime was verified on 21 January 2020, 02:35:41 UTC by Igor Keller (IKI) of France using an NVIDIA GeForce GTX 1080 in an Intel(R) Core(TM) i5-4460 CPU @ 3.20GHz with 16GB RAM, running Microsoft Windows 8.1 Professional with Media Center x64 Edition. This computer took about 26 minutes to complete the probable prime (PRP) test using GeneferOCL2. Igor Keller is a member of the Gridcoin 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 17 hours, 52 minutes to complete the primality test using LLR.
