Install Prime95/Mprime on Ubuntu 20.04

How do we install Mprime or Prime95 on Ubuntu 20.04 using apt? Or must it be installed from a .deb/tar.gz file?

I am planning to stress test my Threadripper CPU using this application.

The software is available for download from the developers at mersenne.org.

Download the Linux 64-bit version of the tar.gz, then extract the archive.

You can open the readme.txt file, which includes a section called "INSTRUCTIONS".

Feel free to read the entire file for more details on how to use the software, but here are the basics (info pertaining to Windows/MacOS is redacted):

Create a directory to hold the executable and associated files. Make sure you have write access to this new directory.

Now run the program. In Linux, 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.

This being said, there are probably better ways to benchmark your CPU than Prime95. See the topic: CPU benchmarking utility for Linux
