There is an independent effort to help distributing the Binary Radio Pulsar search (BRP) to many different platforms by distributing together with the Debian Linux distribution. From there the package also tripples to other distributions like Ubuntu, Mint and (likely) Raspbian. It is however unclear how long this transition to other distributions takes.
Just as an update on where we are with this: In Debian's development branch (aka "sid" or "unstable") an update to the Debian package for the BRP search app has arrived. Now flagged as packaging-version 10 (https://packages.qa.debian.org/b/boinc-app-eah-brp.html), it is still the same source tree as the initial release but is now compiled with g++ version 5 instead of g++ 6 (or 7). This is closest to the g++ version used for the official releases. Compiled with g++ 4.9 or g++-5, we _no longer_ get tasks tagged as "invalid". With g++-6 oder g++-7 it was between 10 and 25 percent that could not be validated. This dependency on the compiler only affects the BRP code, not the FFTW library.
Besides the compiler, the following was changed from the original source tree:
No more checkpointing. This is meant for all the 24/7 machines out there and for laptops alike. Also, the raspberries will like to see fewer I/Os with their SD card. So, basically, everyone should benefit - for the short-running BRP this is.
Fewer status updates. Only every 2-10 minutes the boinc manager updates the remaining compute time.
Allowing for BRP-specific wisdom file at /etc/fftw/brp4.wisdomf
The dependency on the older compiler version may delay backports to distributions that regular users are using. Ubuntu is very fast (already addressing it on https://launchpad.net/ubuntu/bionic/+source/boinc-app-eah-brp) for its development branch. To shorten the delay, users could compile the package themselves and not wait for the official backport. I need some extra time to prepare respective instructions.
Yes, it is pricey but they have these nice coreboards that cost "only" 95$ for 2gb and 115$ for the 4gb-model. My secret major goal is to design a "cluster-main-board" with a integrated GBE-switch were you can plug 16 of these board's in. Two GBE-Ports on the back of the mainboard that you can stack up multiple.
So I bought this board to get some performance number's to see if it's worth to design such a cluser-board. And yes this board is powerfull. The two A72-cores(@1.8Ghz) finishes a BRP-WU in around 6200sec. The A53-cores(@1.4Ghz) need's around 4.5h for a WU(not exactly testet yet). And I could use the GPU.
Powerfull yes but powerfull enough? Not shure now. Let me know what you are thinking?
Please do elaborate a bit on the secret major goal :)
Can you also post GFLOPS and power draw metrics please?
Can’t say I have seen them for sale but I did notice it looks like it has a PC power connector on the right so you’d need a PC power supply or the ones they sell (it didn’t have an Australian power supply only EU and US).
You would possibly have problems keeping it cool without forcing air over the Sopine modules.
From the screen shots it would appear they run Android, Ubuntu Mate, arch Linux and armbian. It should work as 7 separate computers as each Sopine module has its own MicroSD card.

i had to go to the Raspberry Pi site www.raspberrypi.org to confirm that they have a new model. I’m surprised they haven’t been pushing it more.
They are AUD $46 from the Australian distributors. I’ve asked for a better price if I order 11 of them (has to be over $500 before they offer a discount). If nothing else I would upgrade the one acting as a proxy server for the faster network speed.
This is exciting, though the cost of an 8 port PoE gigabit switch is MUCH higher than the Netgears I've been net booting my existing Pis though! I can't wait to try the improved PXE booting though to see if a wider variety of low cost switches will work. My local source does not yet have a date for these.
