Create a directory and decompress the file you just downloaded. Windows 10, 8, 7, Vista, and XP have built-in unzip features.Other Windows users can choose from a variety of decompression programs. We use 7-zip.Linux and FreeBSD users should use the standard tar and gzip decompression utilities.
Start the program! Linux and FreeBSD users should run the program from the command line with a -m switch, i.e. ./mprime -m
Enter your optional userID created on the website in Step 1, and optionally name your computer. We recommend Windows users select Options Start at Bootup or Start at Logon.
That's all you need to do! The program contacts a central server called PrimeNet to get some work to do. Usually the program and PrimeNet know the best work to assign, but it's up to you!You can administer your account and computers on your userID's account page. Once you complete a workunit you can track your standings on thecompetitive stats pages the server updates every hour (see Top Producers in the menu, left, for more stats). You can monitor each of yourcomputers' progress, even remote-control the work assignments they request using your userID's CPUs page!
Linux and FreeBSD versions can also be set up to run every time you restart your computer.

Prime95 has been a popular choice for stress / torture testing a CPU since its introduction, especially with overclockers and system builders.Since the software makes heavy use of the processor's integer and floating point instructions, it feeds the processor a consistent and verifiableworkload to test the stability of the CPU and the L1/L2/L3 processor cache. Additionally, it uses all of the cores of a multi-CPU / multi-coresystem to ensure a high-load stress test environment.
Today's computers are not perfect. Even brand new systems from major manufacturers can have hidden flaws. If any of several key components such as CPU, memory, cooling, etc. are not up to spec, it can lead to incorrect calculations and/or unexplained system crashes.
Overclocking is the practice of increasing the speed of the CPU and/or memory to make a machine faster at little cost. Typically, overclocking involves pushing a machine past its limits and then backing off just a little bit.
For these reasons, both non-overclockers and overclockers need programs that test the stability of their computers. This is done by running programs that put a heavy load on the computer. Though not originally designed for this purpose, this program is one of a few programs that are excellent at stress testing a computer.
The Prime95 Wikipedia page has an excellent overviewon using Prime95 to test your system and ensure it is working properly. The tips presented there should be helpful regarding how long to runthe torture test and provide a solid guideline on how long to run the Prime95 stress test.
Please consult the readme.txt file for possible answers. You can also search for an answer, or ask for help in theGIMPS forums. Otherwise, you will need to address your question to one of the two people who wrote the program.Networking and server problems should be sent to GIMPS admin. Such problems include errors contacting the server,problems with assignments or userids, and errors on the server's statistics page. All other problems and questions should be sent toGeorge Woltman, but please consult the forums first.
The source code for the program is highly optimized Intel assembly language. There are many more-readable FFT algorithms available on the web and in textbooks.The program is also completely non-portable. If you are curious anyway, you candownload all the source code (38.8MB). This file includes all the version 30.19b20 source code for Windows, Linux, FreeBSD, and Mac OS X. Last updated: 2024-06-02.
The GIMPS program is very loosely based on C code written by Richard Crandall. Luke Welsh has started a web page that points to Richard Crandall's program andother available source code that you can use to help search for Mersenne primes.
At this time, Ernst Mayer's Mlucas programis the best choice for non-Intel architectures. Luke Welsh has a web page thatpoints to available source code of mostly historical interest you can use to help search for Mersenne primes.

The E-Primer acts as a guide to this tool, providing all the necessary knowledge to make E-Prime accessible to everyone. You can learn the tools of psychological science by following The E-Primer through a series of entertaining, step-by-step instructions that recreate classic experiments.
Your staff, from the technicians to customer support, are always eager to help, and go far beyond good customer service. Your technicians have helped me trouble shoot both over email and over the phone, and always take care to thoughtfully explain it in a way I can understand. Your customer service has been very receptive to my requests, such as requests to watch certain webinar videos. Needless to say we are happy gold members with E-Prime!
I have to thank YOU and the team for your quick reactions, for taking my problems seriously and for not giving up looking for possible solutions. As a customer one does not encounter that so often. If all support teams all over the world would be like you, PC life would be a bit easier! At the moment I have no more questions. I am very happy to use E-Prime now on my own PC!
I have contacted PST support several times when faced with problems with an experiment I have been designing for the past six months. Each time, they have been quick to respond and have been incredibly helpful. They offer suggestions and even looked through my program to find out the problem. I am not sure I would have fixed this latest problem with markers showing up inconsistently without the help of the PST Support team. The customer service received from PST is by far the best I have ever experienced when working with any product or software. I wish the product support for all of the programs I have to use to do research were as excellent as the PST support. I greatly appreciate all of the help with my program. Whether it be a mistake I made or something as simple as un-checking a box in an object, they always help me when I am the most frustrated with problems arising when conducting an experiment. Thank you PST Support Team!
This was the first time I'd contacted PST support and I expected - based on experiences with other support teams - that I'd get a generic, auto-generated response. I was very pleasantly surprised to receive (very quickly!) a personal email from Devon, who addressed the issues I was having and offered suggestions for how to fix them. When I didn't understand all of the suggestions, he wrote back and clarified and was very patient throughout the experience. I am so grateful to have had such a nice experience with your support staff. Ultimately the problem was resolved and I am very thankful for the help I received from Devon. THANK YOU!!!
I have been using E-Prime for 10 years now. Your technical support has always been and continues to be the most helpful support with which I have ever interacted. Thank you for the great work that you do!
I'm very impressed with the quality of response I receive from PST. The technical consultants, particularly Devon, are amazing. My graduate students and I are very grateful for such excellent support as we learn e-prime.
Usually Prime95 will detect an error within a matter of minutes if an overclock is not stable, however many people like to let the system "burn-in" overnight to ensure long-term stability. FPrime95 is a small and easy to use application that allows you to find Mersenne Prime numbers. Mersenne numbers can be proved composite (not prime) by either finding a factor or by running a Lucas-Lehmer primality test. Prime numbers have long fascinated amateur and professional mathematicians. An integer greater than one is called a prime number if its only divisors are one and itself. The first prime numbers are 2, 3, 5, 7, 11, etc. For example, the number 10 is not prime because it is divisible by 2 and 5. A Mersenne prime is a prime of the form 2P-1. The first Mersenne primes are 3, 7, 31, 127, etc. There are only 40 known Mersenne primes. 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. Anyone with Internet access, including AOL, CompuServe, and dial-up ISP users should use this method. 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. Recommended for computers with no Internet access or with some kind of firewall problem that prevents the automatic method from working.
