General infos

- checkpoints every 1min
- fixed credits
- max WUs in progress = 50 per core
- anonymous platforms are not allowed
- deadline = different

CPU cache usage

FFT length * cpu cores or -tx = max CPU cache.

AVAST issues

There seems to be a problem with the Avast software. To exclude the website from protection check out this site:

http://www.getavast.net/support/managing-exceptions/

Also happened by getting:

transient upload error


Current issues / solutions

invalid WUs

Gerbicz check failed many times and aborting (check your CPU, RAM, OC, heat etc.)

Invalid certificate BOINC Client

If you are getting an error in your BOINC client log or you cant upload/download new WUS:

Scheduler request failed: Peer certificate cannot be authenticated


you must update/replace the ca-bundle.crt from the BOINC client.

TOP5000 primes / How to report a prime

If you have found a TOP5000 prime I will send you the prime by PM. You must enable in Community preferences: Notifications Immediately, by email to get a message.

1. If you dont have an account create one at https://t5k.org/bios/newprover.php, you will get a password by mail to login.

2. Create a new proof code (you only need one proof code to report all primes based on this project). Choose llr and in the last field where you can find "none" write SRsieve,CRUS without any spaces. If you have already a proofcode click on the code and go to point 3

Change the program from llr, listed below to PRST



3. Enter the prime and submit.



Currently primes must have 552034 or more digits to get into the list

Reporting primes

The project will only reporting primes in bases with low k's left. You will find them in the base results and the primelist.

Hardware requirements

non AVX AMD/Intel CPU 2.3Gh+

Recommended:

AVX,AVX2/FMA3, AVX512 compatible AMD/Intel CPU 2.3Ghz+

AVX/FMA3 producing more heat on your CPU, you need a really good cooling! Dont run the CPU if you have 80°C+ core temp (based on the CPU model).

Apps runtime

short -->sec-2h30min
average -->h-6h
long -->1h+ (up to 10h+)
standard -->sec-2h30min

Based on an i7-4930K@3.8Ghz. Enable only apps you can have done in time with your computer.

List of apps:

srbase = Sierpinski / Riesel Base
srbase2 = Riesel Base
srbase3 = Sierpinski Base
srbase4 = Sierpinski / Riesel Base - short
srbase5 = Sierpinski / Riesel Base - long
srbase6 = Sierpinski / Riesel Base - average
srbase7 = Riesel Base - short
srbase8 = Sierpinski Base - short
srbase9 = Sierpinski / Riesel Base - average2
srbase10 = Sierpinski / Riesel Base - average3
srbase11 = Sierpinski / Riesel Base - long2
srbase12 = Sierpinski / Riesel Base - long3

Remove only the lines you dont need to run short apps.

Change the -tx commandline to use all of your cores you have / want to run.

Trial Factoring

GPU Trial Factoring of Mersenne Prime candidates

- checkpoints are working every ~1min+ (depends on your GPU card)
- after a restart you will notice a 0 elapsed time, dont worry. You can always check your stderr.txt file where you are at current state
- GPU max WUs in progress limit = 80 (current process)

available apps:
- Windows / Linux 64bit opencl for AMD cards, CUDA for Nvidia cards

Unsupported GPUs:
- FireStream 9170 and Radeon HD 2000 / 3000 series (as kernel
compilation fails)
- HD5xxx

Running mfakto (opencl)
AMD Catalyst 11.4 or higher is required
- if driver < 11.10, install AMD APP SDK 2.5 and make sure
%AMD_APP_DIR%/lib/x86_64 is in the path.
- Microsoft Visual C++ 2010 Redistributable Package for your platform and
language
- min_opencl_version 101

Running mfaktc (CUDA)
- CUDA10
- driver >= 410.48

- CUDA11
- driver >= 450.80.02*

- CUDA12
- driver >= 525.60.04*

*driver backward compatibility

Errors

./mfaktc.exe: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by ./mfaktc.exe)
update your GLIBC version

Linux:
Install Cuda toolkit 10.1
https://developer.nvidia.com/cuda-10.1-download-archive-update2?target_os=Linux&target_arch=x86_64&target_distro=Ubuntu&target_version=1804&target_type=deblocal
