News of the research projects that Gridcoin pays for and of the Gridcoin releases, newest first. Press releases that companies pay to publish here are in the list too, marked as sponsored: Gridcoinstats does not write them and does not stand behind what they say.
Hello!
I am writing this post to summarize a little the news that we have had over the last month. As we have already commented on the forums, we detected a problem with the checkpoint files that caused many windows tasks to end with an invalid result. After several tests and several attempts we have managed to detect where the problem was and solve it. Due to this, we have implemented some of the improvements that we had planned for the checkpoint file. We have made it more robust. We have…
Hi,
from tomorrow there will be 2 weeks holiday and so there will be no physical access to server in case of problems.
Be sure to have a backup BOINC project in case of problem here for not let your clients without works.
Thanks
The tasks are coming!
We have finished the work on time and now you visit the new version of the website. We will be updating and adding things.
Today we are also testing a newsletter. You are many people, so it still takes a while to reach you (more than 3000 e-mails sent now).
We are going to go little by little to verify that everything works correctly and to avoid saturating the server.
Thank you so much!
Best,
Jesús.

Dear users,
With a little delay compared to our original idea, next Thursday, July 7th, we will relaunch the DENIS project.
Over the next few days we will be updating the website and some features, so it is possible that some things may temporarily malfunction. When all the modifications have been completed we will notify you. If you see a bug before that warning, don't worry about what might go wrong.
However, if something generates doubts, you can ask us in the forums.
Thank you all for your…
Dear volunteers,
After this second phase of testing and with version 7, the results are as expected. We want to review some small detail in case we can reduce the number of errors that occur in clients. Currently they are in less than 0.5% of the cases and we believe that it is mostly due to situations in the client, but if we see options for improvement, we will do it.
With these results, we are ready to move on to the next phase, so we will be working on it for two or three weeks. We are…
Dear all,
After the second batch of simulations the result were similar: 99.5% of the simulations endend satisfactorily; 0.5% returned apparently normal but with invalid values. These results are stable enough to be able to perform a larger test. We actually need it to know if this small percentage of errors is due to something in the code or something in the clients. Currently the number of users returning invalid results is so low that it is hard for us to figure out what the difference…
Hey Everyone,
I'm going to turn the project off for a little while to cancel a bunch of WUs. There's no easy way to cancel only Nbody WUs (unless I want to sit and cancel them 999 at a time, because of how BOINC servers are set up), so I'm just going to cancel ~75% of the currently available jobs. This will reduce the enormous Nbody backlog and hopefully get things flowing more smoothly.
Best,
Tom
Dear volunteers,
We are analyzing the first batch of simulations and so far the results are quite satisfactory. 98.35% of the tasks launched once the problems with the validator were solved, run without problems and their results were valid. 1.12% of them failed to boot into the client (all under the same user and host). 0.53% were tasks that were executed satisfactorily but whose results were not validated when comparing whit the results of the other volunteers. We are studying what could…
Dear users,
With the update of the boinc version and the relaunch of the project, there was an important change that we had forgotten to mention. Since the last time the project was in operation, the data protection regulation and also our perception of it has changed. Due to this, with the new version of BOINC we have taken the opportunity to give you the greatest possible control over your data and what can and cannot be done with it. That is why, by default, we do not assume any permission…
Good afternoon to everyone,
The problem with the validator has already been solved and currently the project is stable and processing the data that is arriving. We will continue to check if there is any other problem with the database, but it seems that the problem that caused the crashes has already been solved.
Soon we will launch another small batch of simulations to evaluate how the program is working. We have detected that in a few cases unexpected results return and we want to analyze…
Dear all,
As some of you may have read on the forum, we were experiencing some issues with the validator on Friday. These problems caused the server to be saturated and the database to crash (hence the access problems). We are analyzing the problems, as soon as they are resolved we will reactivate the processes to receive the tasks you have waiting for and be able to award the scores.
Again, thank you very much for your patience in this…
Hey Everyone,
I will be turning off the mysql DB for the server at midnight UTC (8PM EDT) for 12 hours. Last time I kept some processes running, but turned off the WU generators in order to give things time to catch up from the drive failure (they are currently still off). I don't think that the server finished rebuilding then, so I will be turning all MW processes completely off for 12 hours, and then hopefully by the time I turn things back on again, the drive will have rebuilt.
If you only…
NFS@Home has found a new record penultimate prime factor! 7,889M, which is a portion of the number 7^889+1, splits into 151-digit and 160-digit prime factors. This 151-digit prime factor beats the old record, a 147-digit prime factor of 12^293+1. Congrats to all contributors who helped set this new Cunningham project record!
Dear users:
We're back! Not 100% yet, but we want to start testing the app and fixing any issues that may arise.
We have just released a small batch of tasks to see how it works (almost 1000 simulations). If all goes well, when those will be finished, we will send a package with approximately 40,000 simulations.
We had some problems with the update of the BOINC version so we imagine that we will have to solve small details. We ask for your patience at this re-start.
If the tests go OK, the…
Hey Everyone,
I'm going to be turning the project off for roughly 24 hours starting at 1 PM EST (17:00 UTC) on March 25th. This time will do three things: 1) It will allow me to clear the transitioner backlog, 2) It will temporarily stop generating new WUs, so we can work on the backlog of WUs waiting for validation, and 3) It will help the server rebuild the replacement drive that we put into the machine on Monday.
There will probably be at least 12 hours of downtime during this where you…
Hello Everyone,
We will be taking the server down at 1PM NY time to do a reboot and ensure that the replacement drive is rebuilding correctly. We plan on being out for a couple hours at most.
Best,
Tom
Hey Everyone,
The server appears to be having some connectivity issues. Additionally, one of the drives on the server appears to have failed - luckily things are mirrored so we haven't lost any data. However, I need to make a backup of things, which could take several hours. Once everything is backed up I'll try to clear out this transitioner/validator backlog and get things up to speed again.
Best,
Tom
We have measured the original shape and mass of the dwarf galaxy that was ripped apart to make the Orphan-Chenab Stream! The paper is out today: https://iopscience.iop.org/article/10.3847/1538-4357/ac498a Eric Mendelsohn was the lead author on this study.
Professor Heidi Jo Newberg has made a ~14 min video explaining the topic here: https://www.youtube.com/watch?v=ma44b8-SLcA, and a longer ~24 min video with more information here: https://www.youtube.com/watch?v=eATUWTwdOgc

de_modfit_85_bundle4_4s_south4s_gapfix_bgset3
And I have put up the following…
Hey everyone,
My name is Dylan DeNicola, and I recently joined the MilkyWay@home project as a Project Developer and Project Tester, so I wanted to introduce myself. I'm currently an undergraduate sophomore at RPI, and I'm working towards a computer science major. I plan on working on the development of the BOINC software for the project, and for now, I will be working on updating the server to the latest version of BOINC, getting our GitHub repos up to date, and doing general bug fixes. It's a…
On 25 Jan from 12.00 to 16:00 there is a scheduled power off in my city due to electrical maintenance in the area.
So far the battery power supply of server handles up to 3h of blackout, so it is not know if it can stay up for 4h, but I hope so.
However, even if the server is on, it will be not reachable from the network as all net devices of the area will be powered off during that time.
Thanks
