#41 Re: Raspberry Pi

Post by Dirk Broer »

Though the oldest records of the Raspberry Pi family claim that the arch version was round and actually tasted like raspberry, I'll confine myself to those models that were designed by the Raspberry Pi Foundation.
In the beginning that was but one Pi and it's model was..Model B. Not a bad beginning when you're constructed in the same country that gave us Terry Pratchett. Mind you: it was still 2012 back then.
Model B (aka 0002) later -2013- got a brother named Model A (aka 0008), which was cheaper and simpler by virtue of having no network capability, just one USB port and having no more than 256MB of RAM.
Introduced in June 2014 there was an illegitimate kind of offspring introduced that needed a Compute Module development board to be able to function, the so-called Compute Module(aka 000d), known for its hideous prices at the resellers, especially the combo of development board and compute module, charging hundreds of euro's for them. They can stick them where the sun doesn't shine! Actually a very painful experience, viewed by the GPIO pins...
In 2015 the youngest family member of the first generation (though some claim it was a child of Model A) saw the light: the Raspberry Pi Zero (aka 900092), that for the sake of cheapness had lost all that was not strictly needed for basic operation, including a large part of PCB surface.

That first generation has in common that they are all based upon the Broadcom BCM2835 SOC, featuring an ARMv6Z architecture ARM11 CPU and a VideoCore IV GPU. There are some minor variants/descendants worth mentioning of the first generation:
Variants:
Where there is profit there will be people or companies that will help themselves to a share of it, sometimes even without knowledge of the original manufacturer. In a klatch-as-klatchian-can the models 0003 and 0004 can be said to be minor variants of 0002, but China-made 000d -that came out in both red and blue instead of the familiar green- defies family resemblance. Revision 2.1 of the Model B (aka 00oe) was again UK-made, while 000f was again China-manufactured, but green this time.

Descendants:
Model B sprouted Model B+ (aka 0010) in July 2014. B+ gave us the basic form of the modern Raspberrie Pi's, including the four USB 2.0 ports. The model B+ was also manufactured in China, using a fitting red PCB and also reporting as 0010, just like the original.

Model A sprouted Model A+ (aka 0012) -we observe a pattern here- in November 2014. A+ suffered from dwarf-growth, albeit not in such a severe form as their youngest sibling(?) Pi Zero. It even managed in a later form (aka 0016) to get more memory, 512 MB.

Model Zero has, besides it very basic 1.2 version a 1.3 version (aka 900093, with MIPI interface), a W version (aka 9000C1, Wireless plus Bluetooth) and a sort of illegal WH version (same as previous but also with onbard GPIO headers).
Image
November 2014 family picture of the first generation, taken before the advent of the Raspberry Pi Zero.

The 2nd generation was kicked off by the introduction in February 2015 of the Raspberry Pi Model 2B (aka a01041), a model that would have made Hamlet proud -if he had lived that long. The Model 2B was a jump foreward, as it used a BCM2836 SOC, featuring a Quad-core ARMv7-A architecture ARM Cortex-A7 CPU and.... a VideoCore IV GPU. RAM was increased to 1GB and the speed was increased from the original 700 to 900 MHz.
After the introduction in 2016 of the 3rd generation Model 2B was produced in a variant 2B 1.2 (aka a22042) which used a BCM2837 SOC, featuring a Quad-core ARMv8-A architecture ARM Cortex-A53 CPU and.... a VideoCore IV GPU. This quickly introduced hybrid 2/3 version may be the reason that there are no further descendants and/or subversion of the Model 2. The (un)availabiilty of the BCM2836 SOC may play another role here.

The 3rd generation first saw the light with the introduction in February 2016 of the Raspberry Pi Model 3B (aka a02082), a model that got much lamented for not being named Model 3.14. The Model 3B was another jump foreward, as it used a BCM2837 SOC, featuring a Quad-core ARMv8-A architecture ARM Cortex-A53 CPU and.... a VideoCore IV GPU. Speed was increased to 1200 MHz, and WiFi and Bluetooth were standard onboard features.
Model 3B has variants produced in Japan (aka a32082) and in Brazil (aka a02082), the later made with a blue-green PCB.
A descendant of Model 3B is the Raspberry Pi Model 3B+ (aka a020d3) that differs in a still higher clockspeed (1400 MHz), faster ethernet, two-band WiFi, later bluetooth version and a metal-covered SOC.
The third generation also features a new Compute Module development board with a choice of two Compute Modules: Compute Module 3 (aka a020a0, with 4GB eMMC) and a Compute Module 3 lite (with provision for a SD-card)

You'd have to run Android on the Pi then, as WCG offers no Linux/ARM applications.

There seems to be a few Android distros out there - including a PAID FOR one - yikes. Which would you recommend please?

Frankly: none.
If I were to run Android on an SBC, I'd buy an Odroid. Or, even better: an ASUS Tinkerboard. I might even want to try to install it on my CubieBoard 4 again too -if that still works.
The Raspberry Pi 3 and 3+ run perfectly under Raspbian or even Lubuntu/ARM, but my experience with android on the Pi was a total disaster. YMMV..

I can't answer that, but you could use the pi to dip your toe outside the WCG pool. There are many other interesting projects on boinc. Of course what you crunch is entirely your choice.

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)

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.

I've even ordered at two different stores, to see which courier service/shop combination will be first.
When I was courier myself I once arrived together with two others...

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).

My pi3 rack is pictured in post #69 - before I put on heatsinks. Actually - I see 3 still need them, I wonder if that explains the performance difference I've been seeing

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
processor : 0
model name : ARMv7 Processor rev 3 (v7l)
BogoMIPS : 270.00
Features : half thumb fastmult vfp edsp neon vfpv3 tls vfpv4 idiva idivt vfpd32 lpae evtstrm crc32
CPU implementer : 0x41
CPU architecture: 7
CPU variant : 0x0
CPU part : 0xd08
CPU revision : 3

running a Pi4 with a 64-bit kernel gives:
cat /proc/cpuinfo
processor : 0
BogoMIPS : 108.00
Features : fp asimd evtstrm crc32 cpuid
CPU implementer : 0x41
CPU architecture: 8
CPU variant : 0x0
CPU part : 0xd08
CPU revision : 3


On the net I found a similair output for an Odroid-C2, running Android:
Hardware : ODROID-C2
processor : 0
model name : AArch64 Processor rev 4 (aarch64)
Features : fp asimd evtstrm crc32 wp half thumb fastmult vfp edsp neon vfpv3 tlsi vfpv4 idiva idivt
CPU implementer : 0x41
CPU architecture : 8
CPU variant : 0x0
CPU part : 0xd03
CPU revision : 4

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
processor : 0
model name : ARMv7 Processor rev 1 (v7l)
BogoMIPS : 10.08
Features : half thumb fastmult vfp edsp thumbee neon vfpv3 tls vfpv4 idiva idivt vfpd32 lpae evtstrm
CPU implementer : 0x41
CPU architecture: 7
CPU variant : 0x0
CPU part : 0xc0d
CPU revision : 1

to be continued

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

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
