This is the reservation thread for the Factorial Prime Search sieving. This is a combined sieve of the form n!± 1 for n<1M. For more information about the Factorial Prime Search, please see this forum post.

Before reserving a range, please visit the Welcome thread for instructions. NOTE: Manual BOINC cobblestones are available for this sieve. Also, this sieve is best suited for 64 bit OS machines.


  • fsieve_2530G is the current sieve file and can be found here: Factorial Sieve file. Also get the fpsieve.bat file (fpsieve.sh for Linux).
  • fpsieve 0.2.4 is the current version we are using and can be downloaded here: Factorial Sieve Software
    Available Software: 32 & 64 bit Linux, 32 & 64 bit Windows
  • The factor upload folder is located here: Factor Upload
  • NEW GPU FACTORIAL SIEVE PROGRAM
    Rogue has written a new OpenCL GPU factorial Sieve program. Links to the most recent version of the program as well as discussion about the new sieve may be found in the Factorial/Primorial Sieve Discussion thread.

User Stats for manual ranges

To reserve a range, simply post in this thread the range you wish to reserve, using the following format for your message: Reserving Range Username. For example: Reserving 4510G-4520G Lennart

Factorial n<1M
0000G-5400G Factorial Sieve Archive

5400G+ Available

Review other reservation posts before selecting a range. Also, check to make sure you have the latest sieve file.

2500G: Achieved!!!
3000G: Achieved!!!
4000G: Achieved!!!
???: Final Goal - optimal sieve depth 1+ year


Updating the sieve file
Stop fpsieve. Download the new sieve file and unzip. Edit the -i switch in the .bat (.sh for Linux) file to the new sieve file name. Restart fpsieve.

Multicore systems
Please visit the Welcome thread for special instructions on how to easily utilize all cores.

Process Priority Switch
Default is not to change process priority.
-zz sets lowest priority (nice 20, Low)
-z sets low priority (nice 10, Below Normal)
-Z sets high priority (nice -10, Above Normal)
-ZZ sets highest priority (nice -20, High)

Sample Rates - fsieve_500G sieve file
i7 920 - 1G range in ~7 hours, about 40-41Kp/s and -t4.
E5420 2,5GHz, Windows x64 - 1G range in ~12 hours, about 22,7k p/sec with -t3
Q6600 2,4GHz, Windows x64 - 1G range in ~12 hours, about 22,4k p/sec with -t3
GTX460 - 1G range in ~3 hours, parameters -n1 -N1e6 -t1 -b1000 -s16000
HD7970 - 1G range in ~1,5 hours, parameters -n10 -N1e6 -t2 -b32 -s45056

To keep the thread organized, reservation posts will be removed as updated.
