[wildlife] status update Nové okno
So I've found a bit of a bug in the application where it's not training the neural networks quite right. I'm letting the current batch of WUs clear out of the system. I'm hoping to have a fix soon and once I do I'll release a new set of apps and more workunits.

PPS Mega Prime! Nové okno
On 16 January 2017, 04:34:40 UTC, PrimeGrid’s PPS Mega Prime Search project found the Mega Prime: 543*2^3351686+1 The prime is 1,008,961 digits long and will enter Chris Caldwell's The Largest Known Primes Database ranked 201st overall. The discovery was made by Simon Rawles (rawles) of the United Kingdom using an Intel(R) Core(TM) i7-5960X CPU @ 3.00GHz with 32GB RAM, running Linux. This computer took about 56 minutes to complete the primality test using LLR. The prime was verified on 16 January 2017, 05:06:22 UTC by Ed Goforth (BlisteringSheep) of Saint Kitts and Nevis using an Intel(R) Xeon(R) CPU E5-2620 v3 @ 2.40GHz with 64GB RAM, running Microsoft Windows Server 2012 R2. This computer took about 1 hour 35 minutes to complete the primality test using LLR. Ed is a member of the Christians team. For more details, please see the official announcement.

Vina aplication and work units Nové okno
Since yesterday we have loads of work on server for vina application (Linux 64bit and Windows 32bit).
This is internal research batch of WU (non-commercial).

As soon as possible we will also release Gromacs application for Linux CPU and CUDA cards.

Both applications are Open Source:

Unexpected Power Outage Nové okno
While we didn't get ice here, we had plenty of rain. Unfortunately, I was gone for the day when the power outage occurred so there was no opportunity to fire up the backup generator. Thankfully, everything came back online although it took 3 reboots before the firewall decided it indeed had a hard drive. If you get a download error, etc. for a workunit, please let me know. When there is a major crash, there are usually a few screwed up workunits where the database and the file system aren't completely in sync.

base S844 proven Nové okno
On 31th of Dezember 2016, conf [MM], a member of the team SETI.USA found the last prime for base S844.
The prime 40*844^246524+1 has 721416 digits and entered the TOP5000 in Chris Caldwell's The Largest Known Primes Database.

Well done!

[wildlife] v0.11 apps Nové okno
On my Windows, Linux and OS X systems I'm getting the same results, so I hope this should fix those issues so I can get back to updating the assimilator and getting a steady flow of work going!

Let me know if you're having any issues.

This WU had three completions but no validation

2016 year in review Nové okno
I meant to send this just before the new year, but the boards were down. Better late than never...

Last year was a productive year for NumberFields@home. To summarize our accomplishments:
1. Last May the bounded app completed its multi-year search. It found all imprimitive degree 10 fields with absolute discriminant less than or equal to 1.2E11.
2. Then in July a special search miraculously found the hypothesized field it had been searching for. This search had been running off and on for about 10 months. This field was an A5 extension of Q(√421), ramified only at 2. You can read more about it on this post:
3. The regular decics app spent the majority of the year on the final tier of "Data Set 11" (those WUs with DS-11x271 in the name). You may have noticed on the batch status page that this subsearch is just about done - a really big milestone. The search will continue with the higher tiers over Q(√2).

Thank you to all our volunteers who made 2016 such a successful year!

New application (v 0.10) Nové okno
We are deploying the new version of the application (v 0.10), for all the platforms, including sse2, avx and fma. The new application is way faster than the previous one, thanks to the user Daniel who made it. See this thread (http://gene.disi.unitn.it/test/forum_thread.php?id=135) for further info.

ECM@ARM error, you need more swap Nové okno
Since ECM runs also on ARM I see many error on such systems. Thosesystems are mostly small single board systems as Raspberry Pi or Odroids. They have many cores but less RAM and mostly no swap. The ECM wokunits consume less RAM at the beginning but after some time require adhoc 1 or 2 GB of RAM. Boinc can handle it but not so fast as the RAM is allocated and running multiple ECM workunits in parallel makes it worse. They often allocate much RAM at the same time. tl;dr Configure more swap in your system. Consider the old rule swap size = 2 times RAM for systems up to 2 GB. Here a tutorial how to create more swap space: https://www.digitalocean.com/community/tutorials/how-to-add-swap-on-ubuntu-14-04#check-available-space-on-the-hard-drive-partition

Upgrade to latest BOINC server Nové okno
You may have noticed the forums have been down for almost a month now.

This was mainly caused by an upgrade to PHP7. After trying everything else, we finally decided to upgrade the BOINC web code.

[dna] new DNA@Home runs up and going Nové okno

At least there is a ton of Wildlife@Home work to crunch now. :)

Great to have Wildlife work to crunch. It's a shame to lose Subset, in particular the Android aspect of CSG as a whole. This has always been one of my favorite projects due to it's diversity. It is a great place to come to while away some idle time watching videos, classifying tweets or images. Looking forward to new DNA runs and seeing all the little minor bugs worked out of the other sub-projects. Great to see all the recent progress here. Keep up the good work guys and gals!

[wildlife] new linux apps Nové okno
Hi Travis!

It's working much better now, with only a dozen or so invalid tasks out of hundreds of validated!
Here are the recent figures for my tasks:
State: All (504) · In progress (159) · Validation pending (77) · Validation inconclusive (20) · Valid (223) · Invalid (10) · Error (15)

I have noticed that the workunits are disappearing very fast out of the database. Some of them only persists for 24 hours or so, while others is left since early last week.

I have gathered links for the invalid WUs, and also for WUs where other hosts got their tasks invalidated - see below.

All in all I'm quite happy as it seems like the percentages of invalid tasks and compute errors are decreasing for every day! New WUs also seem to come in at a steady pace now, so I can keep my old Linux cans busy all night! :-)

Keep on the good working!!
Have a nice day!!!

Happy New Year! As many of you are likely aware of, we had an outage yesterday that we are just recently recovering from. The University of Washington campus and surrounding Seattle area had a power outage that lasted for a couple hours. For more info about the outage click here. It may take a day or so to get back to normal operation. Sorry for any inconvenience.
