Gridcoin Stats

I've been asked by several people to post a status update on the situation at Arecibo following hurricane Maria's passage. Unfortunately, at this point we haven't gotten any news. The last information we have is from a couple hours prior to when the eye passed Arecibo. That report said all the employees were accounted for and in sheltered buildings. Since then we've had no news. That's understandable. With power out on the whole island, electronics communications aren't going to be possible for some time. Heavy rains are still expected today, so I'm sure that the primary concern is still keeping everyone safe. Assessment of any damage will take time. Let's hope that everyone is safe, that their homes are intact, and that any damage can be repaired quickly.

We seem to be in the early stages of a system failure for several sub-projects. The [Link] proxy server has flatlined and my running jobs monitor is dipping alarmingly. Please check if you are getting tasks flagged as computing failures, and set No New Tasks if so. [Edit] On closer inspection, it may just be the CMS app. [/Edit] Obviously I'll apologise if this is a false alarm, but it's the wrong time of day to expect a prompt response from the CERN admins.

On 8th of September, Deltik, a member of the team Gridcoin found the last prime for base R514. The prime 30*514^424652-1 has 1.151.218 digits and entered the TOP5000 in Chris Caldwell's The Largest Known Primes Database. Great!

Hey Everyone, Sorry about the errors over the weekend. I put up a set of runs that, while tested locally, still seemed to error on the server. The runs are now taken down and should filter out of the queue over the next 24 hours, going to look into it now. Sorry again, Jake

Looks like I didn't quite fully fix the assimilator bug. Will be working on it today and will keep you posted as I figure things out.

I've added a new application (Exact Batch Norm with Scaled FMP) with some recent updates and improvements, as version 0.33. Let me know if you have any issues with this one!

GPU requirements are the same as for Windows and Linux versions: AMD (HD 5xxx or newer) or NVIDIA (GTX 4xx or newer) GPU with OpenCL support and at least 2 GB of video memory. The MacOS GPU version has been confirmed to work on OS X El Capitan and MacOS Sierra. Older MacOS versions have [Link] poor [Link] OpenCL support and may fail to run the GPU version.

The 101 letters long FTNBK message was broken. Please abort all m3_ftnbk* / g3_ftnbk* workunits as they're not needed anymore. There might be a short break in WU availability as I have to clean up batches that are not needed anymore and prepare new ones. More info will be posted here: [Link] http://www.enigmaathome.net/forum_thread.php?id=1109

In the past, donations were nice to have, but not critical to our operation. As you likely already know, RackSpace is ending our free hosting. While all of the PrimeGrid admins volunteer their effort, equipment, and electricity, as do all of its members, PrimeGrid needs to find and afford a home. In choosing a path forward, we have considered both current and ongoing costs, as well as maintaining quality of service at the levels to which we've become accustomed. In doing so, the best option for PrimeGrid is to purchase servers and house them at a paid colocation service. Moving forward, PrimeGrid needs to cover the 3,500 euro cost of the initial hardware purchase, and then needs to start covering the costs of colocation. Ultimately, we will need to plan for hardware lifecycle as well. We are quite appreciative of the donations we have received towards this effort, and you can see our progress here: [Link] http://www.primegrid.com/donations.php where it quickly becomes evident that we still have a ways to go. Your contributions are greatly appreciated and will help keep PrimeGrid strong and viable in the years ahead. We have done a lot of great work here, and hope to ensure its continued success.

Fixed the issue -- the assimilator is back up and running (which is also the work generator), so work should be flowing again!
