Do you need the Separation WU in progess or should we just abort them and do other work?

The project does not supply an ARM executable, I used instructions posted a some years ago by Jake and a few others to make the executable. See the thread "Raspberry pi 3 and Milkyway@home".

I used the instructions almost exactly as documented. In almost all cases where apt-get couldn't retrieve something I moved on with the assumption that something else had superseded it or its just different in Ubuntu. The final product works so it seems to have been a valid assumption. I did have to rename the executable because what it created didn't match what they documented as the correct name.

During the build I was looking at the results of each step so I didn't redirect the results to a file. Someday soon I'll recompile it for a PI running stretch (or whatever the current "native" OS is at the time) and see if there is a difference.

Separately I might try moving the installation from the current SD card to a USB hard drive but I doubt that will make a significant difference.

Any advice you can offer would be appreciated.

Hi, I'm currently running a locally compiled M@H in Ubuntu Mate on a Raspberry PI3. It's slow, completing tasks in the 210,000-238,000 second range. Any advise you can give me that will improve performance would be appreciated.

Well 2 years later I finally got around to compiling and running Milkyway@home on a Raspberry PI 3 running Ubuntu Mate. I'm running 3 concurrent tasks and have completed 6 tasks, 5 validated and 1 "validation inconclusive". They have run between 110,000 and 120,000 seconds and been awarded between 227 and 230 credits. It's not much in the way of credits but there are few projects that run on the Raspberry platform and fewer still that award any substantive credits.

I used the instructions posted by Clay (cbeckham) and they worked with only a few changes necessitated by the passage of time. Since the time they were posted some packages are no longer in the repositories but they didn't seem to be explicitly needed. The only differences of any significance I noted is that it compiles both applications and the names are no longer of the form milkyway_separation_1.36_unknown-system. I had milkyway_separation and milkyway_nbody in the bin directory when it completed the make. I copied milkyway_separation to milkyway which works. I haven't tried to run the nbody application so I don't know if it will work or get workunits.

Initially it didn't get any WUs in response to the update command but I left it to run overnight and it had downloaded WUs and was crunching by morning.

Jake and Clay, should you ever look at this thread again, THANKS!

It's taken me a long time to get around to this, but...

Are the instructions on how to compile and install M@H for a Raspberry Pi3 still applicable?

Just started happening this evening 20-Sept-16. I submitted it for analysis. Is anyone else seeing this?
For now it's blocked so I won't be doing any m@h processing.

Jake and Clay,
You guys are awesome. Thank you for posting the all the steps you went through to build the app. Now I'll have to get s 2nd PI3 to make and run MW applications.
Which apps did you get and run tasks for? How long did they run and how much credit was awarded?

BTW - From experience running Universe@home on the PI3, you may need to actively cool it if you're running all 4 processors at 100%. It tends to freeze up after a while if you don't.

What's the limit for CPU only machines? I'm running one CPU on a Surface Pro and my max seems to be 3 tasks. Which can be as little as 2.5 hour of crunching.
