Welcome to GIMPS, the hunt for huge prime numbers. You will be asked a
few simple questions and then the program will contact the primenet server
to get some work for your computer. Good luck!

Attention OVERCLOCKERS!! Mprime has gained a reputation as a useful
stress testing tool for people that enjoy pushing their hardware to the
limit. You are more than welcome to use this software for that purpose.
Please select the stress testing choice below to avoid interfering with
the PrimeNet server. Use the Options/Torture Test menu choice for your
stress tests. Also, read the stress.txt file.

If you want to both join GIMPS and run stress tests, then Join GIMPS and
answer the questions. After the server gets some work for you, stop
mprime, then run mprime -m and choose Options/Torture Test.

Join Gimps? (Y=Yes, N=Just stress testing) (Y):
Use PrimeNet to get work and report results (Y):

You must first create your user ID at mersenne.org or leave user ID blank
to run anonymously. See the readme.txt file for details.

You have left the available memory fields at 8 megabytes. You can
increase your chances of finding a Mersenne prime very slightly if you let
the program occasionally use more memory. The readme.txt file has more
information. Do you want to let the program use more memory? (Y):

Number of workers to run (4):

Pick a priority between 1 and 10 where 1 is the lowest priority and 10 is
the highest. It is strongly recommended that you use the default priority
of 1. Your throughput will probably not improve by using a higher
priority. The only time you should raise the priority is when another
process, such as a screen saver, is stealing CPU cycles from this program.
Priority (1):

Use the following values to select a work type:
0 - Whatever makes the most sense
2 - Trial factoring
100 - First time primality tests
101 - Double-checking
102 - World record primality tests
4 - P-1 factoring
104 - 100 million digit primality tests
1 - Trial factoring to low limits
5 - ECM on small Mersenne numbers
6 - ECM on Fermat numbers
