WHAT IS THIS PROGRAM? --------------------- This program is used to find Mersenne Prime numbers. See https://primes.utm.edu/mersenne/index.html for a good description of Mersenne primes. Mersenne numbers can be proved composite (not prime) by either finding a factor or by running a PRP (PRobable Prime) or Lucas-Lehmer primality test. The preferred primality test is PRP because it allows vastly superior error checking as well as the ability to generate a separate proof file that proves the test was run and the results were correct. WHERE TO GET HELP ----------------- The best help is available by asking a question at mersenneforum.org. It can be a little overwhelming at first. Especially with acronyms commonly used as a shorthand (there even used in this file). So here is a quick list of some of the more common acronyms. PRP - PRobable Prime test (this is how we find new Mersenne primes) LL - Lucas-Lehmer test (this is how we used to find new primes) DC - Double-Checking (LL tests must be double-checked with a second LL test) TF - Trial Factoring (can eliminate some candidates cheaply) P-1 - P-1 factoring (also eliminates candidates cheaply) P+1 - P+1 factoring (used in an effort to fully factor tiny Mersennes) ECM - Elliptic Curve Method factoring (used in an effort to fully factor tiny Mersennes) CERT - CERTification (certifies PRP proofs, better and cheaper than a DC) GEC - Gerbicz Error Checking (powerful error cheking and recovery for PRP tests) GPU72 - subproject to TF candidates on GPUs (GPUs TF much better than CPUs) INSTRUCTIONS ------------ Create a directory to hold the executable and associated files. Make sure you have write access to this new directory. In Windows, this may mean choosing a different directory than the standard Windows unzip utility suggests! Unzip your download into this new directory. Now run the program. In Windows, double-click on prime95. In Linux, FreeBSD, Mac OS X command line version, cd to the directory and type "./mprime -m". You may need to install the included libraries. There are two ways to use this program. The automatic way uses a central server, which we call the PrimeNet server, to get work to do and report your results. You do not need a permanent connection to the Internet. The second method is the manual method. It requires a little more work and monitoring. This is recommended for computers with no Internet access or with some kind of firewall problem that prevents the automatic method from working. If you are running this program at your place of employment, you must first GET PERMISSION from your network administrator, boss, or both. This is especially true if you are installing the software on several machines. Many companies have policies that prohibit running unauthorized software. Violating that policy could result in TERMINATION and/or PROSECUTION. INSTRUCTIONS FOR THE AUTOMATIC METHOD ------------------------------------- 1) Connect to the Internet. Create an account at https://mersenne.org 2) Run prime95.exe on Windows or "mprime -m" on Linux. You will see 5 dialog boxes: 2a) In the welcome dialog box, choose "Join GIMPS!". 2b) In the second dialog box, enter your user id and optional computer name. If you are using several computers, use the same user ID but a unique computer name on each machine. An easy-to-remember user ID will be helpful if you plan to visit the PrimeNet server's web page to view reports on your progress. 2c) In the third dialog box, fill in roughly how many hours a day you leave your computer running. Click OK (just close the dialog box on a Mac). 2d) In the fourth dialog box, place constraints on the resources the program is allowed to use. 2e) In the fifth dialog box, choose the number of workers you want to run. Choose the type of work you want each worker to perform. 3a) If a proxy server is the causing connection troubles, see the later section on "SETTING UP A PROXY SERVER". 3b) If the program will not connect to the server, then you will have to use the manual method described below. 4) Disable screen savers or use the "blank screen" screen saver. If this is not practical, consider raising prime95's priority to 4 or 5. MANUAL METHOD INSTRUCTIONS -------------------------- 1) Visit https://mersenne.org/update/ to create a userid for yourself and https://mersenne.org/manual_assignment/ to get an exponent or two to work on. Copy these exponents to a file called worktodo.txt. 2) Run prime95.exe on Windows or "mprime -m" on Linux. You will see 3 dialog boxes: 2a) In the welcome dialog box, choose "Join GIMPS!". 2b) In the second dialog box, uncheck "Use PrimeNet to get work and report results", click OK. 2c) In the third dialog box, place constraints on the resources the program is allowed to use. 3) Disable screen savers or use the "blank screen" screen saver. If this is not practical, consider raising the program's priority to 4 or 5. 4) When done with your exponents, use the web pages again to send the file "results.json.txt" to the PrimeNet server and get more work. WARNINGS and NOTES ------------------ Running this program may SIGNIFICANTLY INCREASE YOUR ELECTRIC BILL. The amount depends on your computer and your local electric rates. It can take many CPU weeks to test a large Mersenne number. This program can be safely interrupted by using the
