Well it was not E@H work units as it did the same with distributed.net. Same errors. I had made an image and used it on all the PIs. Now thinking something was wrong with that image. So, being lazy, tried Berryboot one installing to SD and the other to USB stick. Both now running NEON-BETA. Got Boinc 7.4.23. Not overclocked. Times so far 57.5k to 60k. If no problems after a few reboots and a couple of weeks I'll overclock again. Right now I want stable production.
Had issue with certs, getting work units and finally remembering the default memory settings were why only 3 tasks would run. One of the things that impresses me about this project is the willingness to support so many platforms. Lot's more support issues. That was something I liked about Distributed.net. It was my first project 11-12 years ago. I just do not find their projects that interesting. GWs and Pulsars are very interesting to me.
@robl
I went to your web site last time you mentioned it. Nice site. Good info well documented. But I am old and have limited energy these days so I will take the easy way and give Berryboot a try. Thanks for all the info though.
When you reference free memory where is this defined? It this set in the parameters: "Use at most XXX% of CPU time"
In the boinc manager i'm referring to the Preferences / Disk and Memory use ("Use at most ...percent of memory") values. The usual vmstat and other tools will show will show what memory is really free.

Hi,
has anyone thrown E@H at an Odroid C2 under Android or Linux yet?
I ordered 4 Odroid C2 (4x2GHz ARM Cortex-A53(ARMv8), 2GB DDR3) today and hope to put them to some good use in Einstein.
Any experience from similar computers on whether Linux (here Ubuntu 16.04) or Android will be quicker?
I just came across a Class 10 microSD UHS-1 card. The article said they offer 3 times greater performance then the "standard" Class 10 microSD card. Might be a plus for crunching.
Now for the BIG question: Does the Pi3 support the UHS-1 standard?

The SanDisk 32gig/class10 uhs-1 is compatible with Ubuntu Mate and Raspian.

On the same hardware, performance under Linux and Android should be about the same. Android uses a slighly less efficient way to handle floating point numbers when passing thme to functions ("soft float ABI" vs "hard float ABI", e.g. see [url] https://www.raspbian.org/RaspbianFAQ#What_do_you_mean_by_.22soft_float_ABI.22_and_.22hard_float_ABI.22.3F[/url]), but that should not have a profound impact on the performance of the BRP app.

I am running Ubuntu mate on a Pi3 which requires: ubuntu-mate-15.10.3-desktop-armhf-raspberry-pi-2.img. the 15.10.1 image will not boot. It loads the "Rainbow Screeen of Death" and halts. Yikes!!!! flashback to BSODs.
I don't think its been discussed here but the Pi3 seems to have done away with the push/lock push/release microSD card holder mechanism. It just slips in and is held snuggly. I mention this so if someone else is thinking they got a bad unit this should clarify.
For users who are running the non-beta version of the BRP app on the RPI3, here's some wisdom file to try : store this into a file /etc/fftw/wisdomf (create directory as needed) and restart BOINC.
Unfortunately this will not work for the BETA version of the app, which comes with pre-canned wisdom that cannot be replaced. I'll change that in the next version of the app.
Seems to help a bit and brings per task (CPU) runtime down below 9.5h for the first 4 tasks I've tried it with.

Doesn't fftw 3.3.3 use neon if available? Might be worth trying instead of sticking with 3.3.2.
