Topic 198096

Ok, so this is a copy from this thread on another site. You can look there for the details. Basically, I get this error running Einstein at Home on my Pi2 running Ubuntu. I've included the logs on the other thread.

Any help is appreciated!

GLIBC_PRIVATE not defined in file libc.so.6...

I am running a raspberrypi2 well with Einstein, if this helps:

pi@raspberrypi2 ~/BOINC/projects/einstein.phys.uwm.edu $ ldd einsteinbinary_BRP4_1.42_arm-unknown-linux-gnueabihf__NEON
/usr/lib/arm-linux-gnueabihf/libcofi_rpi.so (0x76f02000)
libpthread.so.0 => /lib/arm-linux-gnueabihf/libpthread.so.0 (0x76ecb000)

The problem is I'm running Ubuntu, not standard Raspbian and really would like to find a way to get it running on Ubuntu.

At long last I found some time to look into this.

I built BRP natively on a Raspberry Pi 2 under Ubuntu Mate (takes forever), and the executable seems to work both under Ubuntu and Raspbian wheezy (needs more tests, tho).

The current build script in the source tar-ball that you can download has only an option for cross-compiling an armv7-neon option, but it's not too hard to extend it for a native compilation.

Stay tuned,

Cheers

There is now a beta-test BRP4

There is now a beta-test BRP4 app version that should run ok under Ubuntu and Raspbian for the Raspi2 (well, any NEON capable ARMv7 board). If you enable getting beta apps in your web preferences for Einstein@Home, you should get this one. It has built-in FFT wisdom, so storing a wisdom file in the /etc/fftw folder manually should no longer be necessary to get the optimum performance.

P.S.: sorry for the long delay in fixing this, but the entire Raspberry PI etc population on Einstein@Home (Raspi 1 & 2 , Odroid, Banana Pi, Parallella etc...) provide only ca 0.04% of the total computing power of Einstein@Home, so this is strictly a spare-time project of mine, because I'm a great fan of these boards (I must have 8 or 9 of them). This should not discourage anyone tho, on a computing power per Watt basis, the Raspi2 is quite decent, so it's a few kWh per year per Pi well spent IMHO.

Well this answers my question: What are those Neon Betas. I am crunching several now on Ubuntu Mate. 4 parallel WUs
