New LLR apps
We have upgraded the version of LLR used on all of our LLR projects to LLR v.3.8.21.
As with the previous version of LLR, it is available in 32 and 64 bit versions for Windows and Linux, and 64 bits for Mac OS.
This release has two major features:
* Support for AVX/FMA3 on AMD Ryzen CPUs. You can expect about a 10% increase in speed on Ryzen processors as compared to earlier versions of LLR.
* A rare bug that sometimes caused errors when using multithreading has been corrected.
If you are using app_info.xml (aka anonymous platform) please upgrade to the latest LLR. The wrapper is unchanged. Upgrading is not mandatory, but is strongly recommended.
If you are not using app_info.xml, you will automatically get the new version with your next LLR task and no action is necessary on your part. If you're not sure if you're using app_info.xml you're almost certainly not using it, and no action is necessary.
Improved Database Stability
I made some more configuration updates to improve database stability. If you notice any database errors, please post about them here.
Certificate update - please update old BOINC clients
Due to Google removing trust for Symantec certificates, we need to update our SSL certificate. This will happen on Monday (Apr 17). The new certificate will ensure compatibility with new webbrowsers, but BOINC clients older than v7.4 may no longer be able to connect. If at all possible, please update your BOINC client.[Link] read more
ESP Mega Prime!
On 3 April 2018, 15:55:55 UTC, PrimeGrid’s Extended Sierpinski Problem Prime Search project found the Mega Prime:
The prime is 3,447,670 digits long and will enter [Link] Chris Caldwell's The Largest Known Primes Database ranked 23th overall. This find eliminates k=193997; 10 k's remain in the Extended Sierpinski Problem.
The discovery was made by Tom Greer ([Link] tng*) of the United States using an Intel(R) Xeon(R) E5-2620 v3 CPU @ 2.40GHz with 16GB RAM, running Microsoft Windows 10. This computer took about 3 hours 45 minutes to complete the primality test using multithreaded LLR. Tom is a member of the [Link] Sicituradastra. team.
The prime was verified on 4 April 2018, 00:17:20 UTC by Gary Bauer ([Link] GDB) of the United States using an Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz with 16GB RAM, running Microsoft Windows 10. This computer took about 2 hours 25 minutes to complete the primality test using multithreaded LLR.
