Add GIMPS (Great Internet Mersenne Prime Search)
What is the name of the app?
GIMPS (Great Internet Mersenne Prime Search)
(Optional) Where is the app hosted?
https://www.mersenne.org/
About the app
It searches for large prime numbers. At one point I got it to run on the PI4, it was slow but it worked.
Confirmations
- [X] I have confirmed that this app is legal and not piracy.
- [X] I have confirmed that this app has never been discussed in https://github.com/Botspot/pi-apps/issues and https://github.com/Botspot/pi-apps/pulls, and it is not in the Pi Apps app list.
- [X] I have confirmed that this app can run on Raspberry Pi.
Their [GIMPS's] Linux (32) build works for me on armhf.. This would probably be pretty easy to make a script for.
Here's some output:

@Crilum are you working on the script or should I try to make a script for it?
@MrBrain295 Here you go:
~~GIMPS.zip~~ Don't use this, it will install x86 and x64 versions...
You might want to edit the description, it's not very descriptive..
@Crilum I tried to run both install-64 and install-32 but the both gave me this error
install-32: 11: status_green: not found
install-32: 15: status: not found
install-32: 18: status_green: not found
. Edit: replacing status_green and status with echo works.
It says when I go to /usr/local/bin and run sudo ./mprime it says that /root/gimps/mprime dosen't exist.
@Crilum I got it to work but now it says ./mprime was marked as an executable but cannot be ran by the OS.

Did you import the app into Pi-Apps and install from there?
status and status_green are Pi-Apps' functions.
It says when I go to
/usr/local/binand runsudo ./mprimeit says that/root/gimps/mprimedosen't exist.
Don't run mprime as root. You should also just be able to run mprime without going into /usr/local/bin.
/usr/local/bin/mprime is a symbolic link to $HOME/gimps/mprime with $HOME being your home dir, in my case /home/pi/. If you run it as root, I guess it thinks your home dir is /root/..
When I run as sudo, it works:
$ sudo mprime
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):
@Crilum I got it to work but now it says
./mprimewas marked as an executable but cannot be ran by the OS.
Which install script did you use? (It sounds like you just ran one) install-32 is for 32 bit systems, install-64 is for 64 bit systems.
If you use the App Importer in Pi-Apps Settings, you can import the app into Pi-Apps, and install from Pi-Apps, which should fix installing the wrong program arch, as well as the bash: status: command not found problem.
@Crilum I followed your instructions but when I run sudo mprime it says:
/usr/local/bin/mprime: 1: Syntax error: "(" unexpected
.
I am new to shell so I’m confused what an “arch” is. Is it the cpu architecture?
Yeah, sorry. arch is short for (cpu) architecture.
If you're on a RPi, you'll probably get something like this: armhf (32-bit):
$ arch
armv7l
or arm64 (64-bit):
$ arch
aarch64
Ok, so if you've imported the app into Pi-Apps like this (or manually with the GUI (Graphical User Interface)):
~/pi-apps/etc/import-app https://github.com/Botspot/pi-apps/files/8507509/GIMPS.zip
Uninstall it (from Pi-Apps) and then install it again. Pi-Apps should install the right program architecture for you.
Can you also send the output of dpkg --print-architecture? (I assume you're on Debian, or a derivative, since you're using Pi-Apps..)
I have installed it through pi apps and removed it through pi apps a few times already without success.
sorry for asking for so many commands, but can you also post the output of file $HOME/gimps/mprime?
This gives us the type and arch of the exectable.
ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=6d053e3f9b870f31508045b9f0af5a4c6c9d9a55, with debug_info, not stripped
Oh, I think I know what the problem is!! I have exagear installed, and I think it was just taking over, emulating an x86 system..
If you have box64 installed, try running it with that.
Yeah sorry I commented but my internet was too slow and your comment appeared first.
We can try building gimps, or we can just make the install scripts use box86 or box64 for running it. We should at least try building gimps first though...
They have building instructions on their website, I think...
I'm downloading the source now..
I think it would be better to add box64/box86 as a dependency so it doesn’t need to be recompiled whenever an update comes out and recompiling for 64 and 32 bit.
Ok, but:
- Using Box86/64 will make the efficiency lower, because box86/64 is translating the x86/x64 program into arm code
- We don't need to build it every time (unless we need it to be up to date all the time), we just need to build a couple debs, and then we can install the debs.
I probably won't be able to try building GIMPS today or tomorrow, so if you want to try it, go ahead!
This might be worth taking a look at...
I suggested this before in the discord, yes this should be used. Prime95 (GIMPS) through box86/64 is the wrong way to go. You should be using the open source multiplatform version from that link. Unfortunately this isn't the same as prime95, there is no GUI to see progress and select settings, and the test takes hours to run by default
