Thanks for sharing - this was

Thanks for sharing - this was supremely frustrating as my Pi 2 Cluster was managed over the UART pins and not the network - when I got the Pi 3s, I could never get this to work.

We've had some disturbances in the clusters last night - several SD Card failures - I was able to replace one last night on a machine that hadn't phoned home since 9/22, should be ok now.  The other is the Node 0 for the Pi 3 cluster, which could impact all other Pi 3s since it is the NAT/Gateway for their network.  I will look in to rebuilding over the weekend.  This event also makes me want to start looking in to network or USB booting and moving away from SD Cards all together.

consider /boot only on the sd card and "/" on a usb drive.  Most reads/writes are to "/" and not /boot except in a kernel change.  This would greatly reduce the chances of file corruption.

From what I can tell no one

From what I can tell no one has posted any real info on using the RPi for E@H at raspberrypi.org in the forums. If no one else is interested in doing so I could write up something along with links to this thread and KF7IJZ youtube videos. I can post it here first for comment and editing. 

 

cheers!

What do you

What do you think?

 

---------------------

 

Einstein@Home is a program that uses your computer's idle time to search for gravitational waves from spinning isolated compact objects (among which are pulsars) using data from the LIGO gravitational wave detector. 

 

https://einsteinathome.org/about

 

If you would like to put your Raspberry Pi 2 or 3 to work helping with the search for gravitational waves the Einstein@home Boinc project has an app for that.

 

Boinc is a program that installs easily on most PCs and SoC such as the Raspberry Pi. Boinc manages the apps that are loaded from the science projects you want to support, such as the Einstein@Home project. 

 

https://boinc.berkeley.edu/

 

The Einstein@Home project has applications that run on the Raspberry Pi to search for signs of gravitational waves. The link below is a long thread dedicated to the Raspberry Pi running the E@H project. We have a small team of very knowledgeable members who can answer questions and help solve problems.

One of our members did two Youtube videos showing his hardware build and software install and setup of his Raspberry Pi Grid or Cluster all running Einstein@Home.

While this build may be more than you are interested in doing it is impressive and there is much to be learned from his excellent work.

 

A few of the RPi E@H team members also maintain blogs documenting their adventures with the RPi running Boinc and E@H.

Great idea. Maybe I should do

Great idea. Maybe I should do a blog article about setting up E@H on the Pi from scratch. No fancy add-ons just a basic install. Unfortunately my blog isn't specific to the Pi but we can always link to a particular post.

I think we need more

I think we need more discussion on what our goal is if we are to do a write up on supporting E@H on a Pi. For example, which OS?, full or minimal install, etc.  Could a thread be a series of links to our various efforts in configuring a Pi to support E@H?  Or would that approach lead to too much info?  For example here is a link http://usefulramblings.org/?page_id=4268 to how to configure a Pi anything to support a separate "/boot" "/" configuration to minimize micro SD corruption.  

Also there are hardware considerations.  Your choice of a micro SD card.  Class 10 and UHS1.  Will this card produce a more reliable performance (less corruption potential) with the constant upload/download (read/write) of work units and results?  

Many of us have web page posts for Piz in a distributed computing environment but how do we make a generic page?  It won't be easy because of the many Linux distros (I am assuming Linux but there is also a windows option).

Just thinking.

In MHO I think we keep it

In MHO I think we keep it simple. A howto on adding Boinc to a Raspian install and how to attach to E@H and join the team. Then anyone wanting something different we take it as it comes. I think if we include too much info we will scare off the less inclined. Since RPi was originally done with education in mind, and still is the focus, it is conceivable a school teacher will want to do this in the classroom for teaching computer science and astro/phyics science.

 

If someone wants to do a write up on another OS or using N30DG's apps then that is great and we can reference those when needed or even as foot notes in the main write up.

 

I want to wait several days so hopefully as many as possible will see this and comment.

 

Cheers!

Hi Folks, because I'm afraid

Hi Folks,

because I'm afraid that Parts of this Board are a little bit orphaned, can some body take a look of this/my Problem:

https://einsteinathome.org/content/computer-12262199-upload-problem

and tell me what to do?

Thx
