Also remember /home/pi/projects/milkyway/build/bin may not be the path to the file you are trying to copy. You may need to replace "pi" with your username on your RaspberryPi if it is different than the default.

Hi vlado101,

Good job!! You are learning...

Lets verify that we have the copied the executable file and have created "app_info.xml".

$ cd /home/pi/projects/milkyway/build/bin
$ ls -l

You should see the "milkyway" and "app_info.xml" files here. If not, post
the output here.

2. If the files are there, then do the following
$ cd /var/lib/boinc-client/projects
$ ls -l

You should see the "milkyway.cs.rpi.edu_milkyway" directory. If not, start here in the instructions:

$ sudo mkdir milkyway.cs.rpi.edu_milkyway

Do these two steps and give me an update.

Here is what the paths should look like:

/var/lib/boinc-client/projects
/var/lib/boinc-client/projects/milkyway.cs.rpi.edu_milkyway
/var/lib/boinc-client/projects/milkyway.cs.rpi.edu_milkyway/app_info.xml
/var/lib/boinc-client/projects/milkyway.cs.rpi.edu_milkyway/milkyway

Hi Mr. Weiss,

Here are the instructions. I uninstalled Milkyway on my server and used the instructions below to reinstall. They worked for me.

Thank you for all of your help!!

Thanks

Title: Compile and Install Milkyway@Home


1. Join Milkyway@Home if you do not have an account.

Site: https://milkyway.cs.rpi.edu/

Note: Record your email address, password and weak account key.
Note: If you do not have a team, join "Raspberry Pi".

2. Make a backup of your current microSD chip

3. Update system and install Boinc (in a terminal shell)

$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get dist-upgrade
$ sudo apt-get install dnsutils whois unzip lsb-release
$ sudo apt-get install chkconfig dos2unix
$ sudo apt-get install git
$ sudo apt-get install cmake
$ sudo apt-get install build-essential
$ sudo apt-get install boinc
$ sudo apt-get clean
$ sudo reboot
$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get dist-upgrade
$ sudo reboot

4. Get and compile the Milkyway project

$ cd /home/pi
$ mkdir /home/pi/projects
$ cd /home/pi/projects
$ mkdir /home/pi/projects/milkyway
$ cd /home/pi/projects/milkyway
$ git clone https://github.com/Milkyway-at-home/milkywayathome_client.git
$ cd milkywayathome_client
$ git submodule init
$ git submodule update --recursive
$ cd /home/pi/projects/milkyway
$ mkdir /home/pi/projects/milkyway/build
$ cd /home/pi/projects/milkyway/build
$ cmake ../milkywayathome_client -DBOINC_RELEASE_NAMES=ON -DSEPARATION=ON -DNBODY_OPENMP=OFF -DSEPARATION_OPENCL=OFF
$ make

5. Create our boinc files
$ cd /home/pi/projects/milkyway/build/bin
$ ls -l
[You will see the output from the compiler.
[In this example we will use the following file name:]
["milkyway_separation_1.36_unknown-system"]
$ cp milkyway_separation_1.36_unknown-system milkyway
[Create and add the following text to the new file]
[note the version number matches our executable]
[remove the space between tags < >]
$ nano app_info.xml
< app_info >
< app >
< name >milkyway< /name >
< /app >
< file_info >
< name >milkyway< /name >
< executable/ >
< /file_info >
< app_version >
< app_name >milkyway< /app_name >
< version_num >136< /version_num >
< file_ref >
< file_name >milkyway< /file_name >
< main_program/ >
< /file_ref >
< /app_version >
< /app_info >

6. Install the executable in boinc
$ cd /var/lib/boinc-client/
$ ls -l
[You should see a "projects" folder. If not, create it.]
[$ sudo mkdir projects]
[$ sudo chown boinc:boinc -R projects]
$ cd projects
$ sudo mkdir milkyway.cs.rpi.edu_milkyway
$ sudo chown boinc:boinc -R milkyway.cs.rpi.edu_milkyway
$ cd milkyway.cs.rpi.edu_milkyway
$ sudo cp /home/pi/projects/milkyway/build/bin/milkyway .
$ sudo cp /home/pi/projects/milkyway/build/bin/app_info.xml .
$ cd /var/lib/boinc-client/
$ sudo chown boinc:boinc -R projects
$ cd /home/pi

7. Attach to the Milkyway project
$ boinccmd --project_attach http://milkyway.cs.rpi.edu/milkyway/ < your_weak_key >

8. Status and Help
$ boinccmd --help
$ boinccmd --get_state
$ more /var/lib/boinc-client/stdoutdae.txt
$ top [press "q" to quite]

9. Results should start showing up in your Milkyway account
Site: https://milkyway.cs.rpi.edu/milkyway/login_form.php?next_url=home.php

===================

1. Uninstall instructions
[The Milkyway@Home group will update the software from time]
[to time. This may cause validation errors in your account.]
[The following will remove the software and you can repeat]
[the steps above to re-install.]
$ boinccmd --project http://milkyway.cs.rpi.edu/milkyway/ detach
$ rm -Rf /home/pi/projects/milkyway
$ sudo rm -Rf /var/lib/boinc-client/projects/milkyway.cs.rpi.edu_milkyway

Hey,

You should definitely be able to crunch MW@home work units on a Raspberry Pi. The trouble is you would have to compile your own version of the client code. We currently don't officially support it, but feel free to download the source from https://github.com/Milkyway-at-home/milkywayathome_client and compile it. You will probably have to do a little work to get all of the dependencies to work, but it should compile and run.

Jake W.

Doesn't seem like you can use a Raspberry Pi on MW@Home. There however is a very active user base for the Raspberry Pi over on the Einstein@Home project.

I've got about 60 tasks "Ready to Report". I guess this is a symptom of the server maintenance? Or did M@H knock off early for the long US holiday weekend? :D
