Okay thanks, I'll probably just put Raspian on it as I can give it other minor network duties too

Give it a go, what's the worst that can happen ? Can't help with the Pi as I've never owned one. All my droids are versions of 4 or 8 core tv boxes. Think I have 11 at the moment in various states of running or not. Biggest issue with all the TV boxes is power. Nearly all have 1A power supplies and to crunch 24/7 you really need 2A supplies or the PSU's die with depressing regularity. :evil:

I just loaded Raspian and am now crunching for yoyo@home. It was a breeze.

Currently allowing 75% of CPU time and keeping an eye on the cpu temperature (I only fitted a little passive heatsink)

My Raspberry Pi's have PSU's of at least 2.5A -up to 3.1A for the Pi 3...
Raspberry themselves have an universal adapter that supplies 2.5A and works virtually everywhere due to the exchangeable connectors, giving you power plug in, micro usb out:

Here's my favorite nerd explaining how Raspberries are meant to be cooled:

Things to look out for while running BOINC on the Raspberry
  • yellow flash in the right upper corner of monitor = not enough juice (Amps, as in ampere)
  • red thermometer in the right upper corner of monitor = cpu is throttling due to overheating

Humph - I am not very impressed by the points awarded (2nd column) by YoYo on my newer Raspberry Pi3. They are only ever a small fraction of the points claimed (first column). The older Pi3 is fine (2nd picture)

Am now running a couple of Rasp Pi3 computers inside a regular PC case. I am picking up 5V power supply from an unused Molex plug (of the type that used to go on IDE hard disks) :o :o

Will be doing the same for Android TV box(es)

You need to get WUProp on those systems and all the others. The ARM systems are great for racking up WUProp hours.

To be honest, I've never understood what WUProp is all about. Off to look for a thread.

I ran it on a Xeon core for a while but it just said something like 'low CPU usage' so I figured it wasn't worth running :P

My Pi-stack. 2 RPi 2 and 2 RPi 3. Also have, not shown, a RPi B+ and RPi 3 B+. They run Pi-hole.net DNS ad blocker. 3B+ also crunches. Run a combo seti and e@h on all except B+. Used copper GPU memory chip heat sinks and a USB 120mm fan for cooling the stack.

Ordered a Asus Tinker Board last night. Going to go with Android and WCG on it. Getting ready for summer months when I have to start shutting down the heavy iron. lol

WCG is a good choice to run. Basically have all my android systems running WCG because it is stable and reliable along with WUProp to keep everything aligned. .

Looked at the CPU specs on the new Pi4 and didn't see a game-changing leap in performance (at least not on paper)

I might be daft but decided to make an offer to an eBay seller for 8 Pi3 instead in the hope that they'd be overstocked. Wish I'd offered less since they accepted right away. Bizarrely I had enough microSD cards from a phase of heavy photography so they are all now running (on computer PSU)

Experimenting with very long-term speculative bunkering on YoYo and DHEP

The ARM Cortex-A72
  • Runs faster than the ARM Cortex-A53 (1500 MHz vs 1400 MHz on the Pi 3+),
  • Makes use of a 3-way super scalar, instead of the 2-way in the Cortex-A53,
  • Makes use of a 5-wide dispatch out-of-order execution for more efficient use of the instruction cycles (the A53 doesn't use out-of-order execution),
  • Has a pipeline depth of 15, vs 8 for the A53,
  • Has eight execution ports, vs 2 for the A53.
You might call the ARM Cortex-A7x the 'i7' category of ARM, while the ARM Cortex-A5x fall into the 'i5' category -there are even ARM Cortex-A3x CPUs that fall into a i3-like category.

The real proof of the pudding is BOINC itself of course. I'll climb my bike and ride to Leidschendam tomorrow to buy the 2GB Raspberry Pi 4 model B -the only model in stock at the moment.

Edit: the only thing worth mentioning about the 15-mile bike tour was that I spotted Scottish Highlanders (of the bovine variety) along the A4 (E19). The shop -that was relocated recently after a fire- no longer has a physical store and is a web shop nowadays. I hope they survive the fire and re-open to the public. I like to feel what I buy, before I buy it.

Those are Raspberry Pi 3 model B+'s, as can be seen from the much bigger WiFi chip as compared to the original Raspberry Pi 3 model B -like mine.

Mine arrived - only to find that I don't have a suitable HDMI cable. Sigh.

I thought I did but turns out mine is mini-HDMI to HDMI, the Pi4 uses micro-HDMI which I've never seen before. Ah well - only £2 but another 2 or 3 days

Mine have still to arrive, but I have a suitable cable -from my de-commissioned BeagleBone Black.
This is the difference:

P.S.: What are you using for cooling? The Pi 4 needs a fan+heatsink combo for BOINC. This is by far the most capable-looking Pi cooler:

Glad you posted. I had only just put on my usual passive copper heatsinks which let me Boinc happily on Pi3. I pulled one off before the thermal glue dried :lol: :lol:

I left the other one on as, TBH, I am mainly keen to see how the Pi4 copes with the server-side of btsk. Actual crunching is very much secondary & only if btsk copes well with extreme bunkering (I think the Pi4 will cope well as an old laptop runs it fine).

Post by Dirk Broer » Thu Sep 12, 2019 1:43 pm

Main competitors for the Raspberry Pi 4 Model B 4GB seem to be the 2GB and 1GB models of the same Raspberry Pi 4 Model B, by virtue of their lower price.
And as long as you're running a 32-bit OS there might be competition from the ASUS Tinker Board or the Odroid XU4, but they're nearly double the price.

Also at almost double the price are the 64-bit Odroid-N2 and the Rock Pi 4.

The Odroid-N2 has an AmLogic S922X -a quad Cortex-A73 @1800 MHz and a dual Cortex-A53 @1900 MHz in big-LITTLE. It also has a eMMC Module Socket and a capable GPU, the Mali G52 MP6 @846Mhz, supporting OpenGL ES 1.1/2.0/3.x, OpenCL 1.1/1.2/2.0, so superior specs as compared to the Raspberry Pi 4. Oh, and it also runs Android 9.x [When can we have a new NativeBoinc, Scole?]

The Rock Pi 4 -that comes in both an A and a B variant with 1GB/2GB/4GB DDR4 RAM that both have already undergone at least 3 revisions so far- has fittingly a Rockchip SOC: the well-known RK3399, which is a Dual Cortex-A72 @1800 MHz coupled to a quad Cortex-A53 @1400 MHz in big-LITTLE. This gets sometimes advertised as a quad Cortex-A72 by nearsighted/incompetent/ruthless marketeers. The GPU is a Mali T860 MP4 @600MHz, supporting OpenGL ES 1.1/2.0/3.x, Vulkan 1.0, Open CL 1.1/1.2 and DX11. It has not only a eMMC module, but also a M.2 connector supporting up to 2TB M.2 NVMe SSD. So, while CPU and GPU do not impress -especially not when compared to the Odroid-N2- the other features are quite good.

Note that it is possible to run the GPU app for MilkyWay@Home, using the ARM Mali T-628, on an Odroid XU4 board, and MilkyWay@Home is not known for having the easiest hardware requirements. The Mali T-628 is -per core- not stronger than e.g. the Videocore IV of the Raspberry Pi...
If you want real ARM GPU power, then use the Adreno 680 of a Snapdragon 8cx.

Funny, running a Pi4 with 32-bit Raspbian gives:
cat /proc/cpuinfo

BogoMIPS : 270.00

running a Pi4 with a 64-bit kernel gives:

Features : fp asimd evtstrm crc32 cpuid
CPU implementer : 0x41

On the net I found a similair output for an Odroid-C2, running Android:
Hardware : ODROID-C2

Android is a 32bit user land and the /proc/cpuinfo information is "emulated" for backward compatibility.
Only "fp", "asimd", "evtstrm", "aes", "pmull", "sha1", "sha2" and "crc32" are valid AArch64 feature flags.
The rest are implied. Running a 32bit program will show the same feature flags as Android on Linux.

An ASUS Tinker Board running Tinker OS 2.03 (Armbian seems to be much better):
cat /proc/cpuinfo

to be continued

BTW: both Pi4's fly through the WEP M2 WUs like hot knives through butter...

Post by Dirk Broer » Fri Jun 05, 2020 2:25 am

Let's say you bought yourself the latest Raspberry Pi, the Raspberry Pi 4B with 8GB of RAM, what can you do with it? And what couldn't be done with earlier Pi's?

Let me first stress that the 8GB, together with the ARM Cortex-A72 allows for a 64-bit OS -e.g. Raspberry Pi OS to be used to the fullest extent.
From the Raspberry Pi 3B on (and even the 2nd edition of the Raspberry Pi 2B) the board had a 64-bit ARM Cortex-A53, but with only 1 GB of RAM. The Pi 4B was originally introduced with 1, 2 and 4 GB, the latter just having enough RAM to be able to run a 64-bit OS (and more than enough to run a 32-bit OS). The 1 GB model has been withdrawn since a few months and a 8 GB model has now been added to the line. That is as much RAM as is there in the PC of my missus, and twice the RAM as in the PC of my daughter! (she uses a hand-me-down Socket 775 Dell that won't accept more than 4GB and is due for a Ryzen 5 upgrade)

What projects have apps for ARM/Linux? And do they cater 64-bit?
*Does anyone have an overview for WCG? MIP and OPN can be done 32-bit natively and 64-bit with a hack at least*

If you have installed a 64-bit OS and want/need to run 32-bit apps, you might need to install 32-bit libraries to do so.
In case of wanting to run 32-bit apps under a 64-bit OS you get a message like "This project doesn't support computers of type aarch64-unknown-linux-gnu" from that project.
You then need to add:

Code: Select all

<options>
  <alt_platform>arm-unknown-linux-gnueabihf</alt_platform>
</options>
to the cc_config.xml file

Would a few Pi s be a useful way to add some cores to the farm without splashing out on yet another Threadripper? Any information on how the per core performance compares with say a 2990WX?
And where is the best place to buy these beasties?

I use the Pi Hut - either on eBay or their own site

Would help if a few more projects supported them

I think that all projects that have Android apps as their sole non-x86 architecture app could easily port it to Linux/ARM, be it either 32- or 64-bit.
If their apps are opensource, even the community could do that.

Okay so I've got my 8GB RPi 4B up and running.
It's lovely and cool (50degC) with it's splendid ICE-Tower cooler.
It's currently running Universe and early indications are that it might produce 20-25K Credits/pd.
I also got it running with a static IP.

I'm ordering another 3.

In the meanwhile I'd appreciate some advice:
Firstly -how to get it connected to btsk?
Secondly - can I use the Linux scripts previously uploaded by scole to set up multiple instances on the Pi (running Raspbian)? There's not much point in having loads of instances but 2 or 3 would be useful.

yes - I use multi-instance on rpi

for btsk - run WUprop in every instance, usual password in gui_rpc_auth.cfg & btsk server IP in remote_hosts.cfg

Then add 3 lines at the end of /etc/hosts on btsk server. For EXAMPLE

Code: Select all

92.168.0.160	rpi1        #boinc= cpu=4   groups=rpi
92.168.0.161	rpi2        #boinc= cpu=4   groups=rpi
92.168.0.162	rpi3        #boinc= cpu=4   groups=rpi
That will find all instances on each

They won't be found instantly BTW - either wait a while or use yellow menu > hover > machine config > re-sync hosts

the multiple instance thing worked. Then didn't. Now after a uninstall/reinstall of Boinc on the Pi, I've got it recognised on btsk which is cool, even if it's only as a single instance. Which on balance is still cool!
The other 3 are enroute!

You can use the the same /etc/rc.local file to auto-start any additional instances. Sounds like a reboot may have killed them off

Can you remind me how this works? Explain like I'm five y.o. sort of thing, please.
Thanks.

Did you wash your hands?

Put this into a file called /etc/rc.local on the Rasp Pi. Save it. chmod +x /etc/rc.local and reboot. It will start an additional instance for every boinc directory it finds commencing at port 31501

Code: Select all

#!/bin/sh -e
# rc.local
# This script is executed at the end of each multiuser runlevel. Make sure that the script
# will "exit 0" on success or any othervalue on error.
#
# In order to enable or disable this script just change the execution bits.

# start all extra boinc instances.  By David Foubister, TSBT
ls -d /var/lib/boinc[0-9]* | while read dir
do
  j=`echo $dir | tr -d a-z/`
  i=`expr 31500 + $j`
  /usr/bin/boinc4k --allow_multiple_clients --gui_rpc_port $i --dir $dir &
done
exit 0

Splendid. I'll try that as soon as I get the chance.
Will it work on windows or do I need something equivant but different?

I think you already use that on your other Linux crunchers TBH. I can see no value in additional instances if they don't auto-start :)

Talk to your Grandfather about auto-start on Windows as I haven't a clue ;)
