Greetings,

I have come to the conclusion that my Pis will continue to outperform my laptop. They are quad core vs the laptop is only a dual core. I suppose it was too much to hope that the laptop would outdo my Pis. Oh well... GO Pis!!! :)

Have a great day! :)

Interesting,

I only ever run any cruncher on 50% CPU. My Pi takes around 10 hours a WU, which equates to 1 WU in 5 hours. My ten year old laptop running just one core does a WU in around 3.5 hours, so way outperforms my Pi.

My 4 year old Intel(R) Atom(TM) CPU Z3735G @ 1.33GHz "Windows tablet"on two cores does a WU in under 5(equal to one every 2.5 hours)hours, so currently my Pi, is at the bottom of my RAC list

Hi Bernie,

All hosts are running 100% CPU
My Pis run 2 WUs each and average between 5 and 10 hours. <- Quad core. Average RAC between 350 - 380 for all
My 13 year old laptop runs 1 WU and averages 4.5 - 6 hours. <- Dual core. Average RAC about 280
My tablet, well it is out of whack. I need to figure out what to do with it. 1 WU took about 15 minutes while another took more than a day. The Run times and CPU times are way out of range of each other.

I really don't expect my laptop to surpass my Pis at all.

My RAC list is:

• Linux
  
• Winders
  
• Pis 1, 2 and 3
  
• Laptop
  
• Tablet
  

Have a great day! :)

I picked up 2 RPi 3b+ to run my backup PiHole DNS at my place and my parents place. Seems to work fine. Neat little device.

I run my prime PiHole DNS in a VM, but noticed traffic slipping through the backup also, and so wanted the backup on a separate device so the internet doesn’t go down if I ever need to reboot or do maintenance on the VM machine.

Greetings,

My first Pi is getting real close to hitting its first 100K total credits and its RAC is over 400. That's the highest RAC I have seen on my Pis. They usually hang around 360 to 380.

I don't know what else to do to increase production on them. I'll have to work on that. ;)

Have a great day! :)

My setup contains two Raspberry Pi 4's with 4GB of ram and they are allowed to run 4 threads at 100%. The rack seems to hang just over 800 each.

I also have a old Dell Venue 8 Pro tablet with a Intel Atom 3740 CPU that can't seem to break 300

Lastly on my current system list is a HTPC with a Core i3 530 which is faster then the Pi's but not by much. It can do about 1200.

So comparing one to the other the Pi's are certainly on the weaker side, but I think we need to remember where they will shine is in parallelism and low power right. Each pi draws how much power compared to the desktop parts we compare them to. I have seen as little as 5-7 watts even for the Power hungry Pi4. In best case most desktop CPU's don't go below 45.

Has anyone looked at the power consumption of lets say a 8 pi setup and how much rack they get from it vs a traditional x86 i5 or i7

I found my Pi4 ran very hot - a simple fan blowing over it has dropped its temperature and I assume has allowed it to run nearer flat out as it's RAC is sitting around 1100.

Only a couple of weeks ago Phoronix actually did a review of the Raspberry Pi 4 and compared it's performance with no heatsink, a basic small heatsink, an active one, and another passive one that was an Aluminium case that also acts as a heatsink for the processor.

Sometimes running with one core not dedicated to Seti will actually increase the total production (assuming no thermal throttling).

Raspberry Pi 4: a full desktop replacement?

The MagPi magazine puts Raspberry Pi 4 to the ultimate test as writer and all-round tech tinkerer PJ Evans uses it for a week as his desktop computer...


As we all know, all very capable, especially so with 4GBytes RAM and twin monitors... All at Raspberry Pi prices!!

Tom's Hardware also has a very good article summarizing the world of the Raspberry Pi:


Raspberry Pi: Projects, Models, Prices, How to Get Started

With over 25 million units sold, the Raspberry Pi is not only one of the world’s most popular computers; it’s also one of the most important. Originally designed to help kids learn about technology, this inexpensive single-board system is the leading choice for makers, developers and hobbyists who want to do everything from building industrial robots to setting up retro arcade machines...

I will check on that. Right now i don't experience any thermal throttling as it is.

For me - only when it gets a decent 3d CAD implementation - the current offering don't even shift the door never mind open it :-(

With the release of the 64bit kernel on the Raspberry pi is there anything we need to do to enable a 64 bit app. When looking at the apps I don't see a current 64 bit Arm program available. Any thoughts.

I have looked at compiling the app myself, but when followeing the links for the source it doesn't appear to be current source.

Can't do it from the official Raspberry O/S, without lot of work.

You would be better off to D/L Gentoo O/S and then it will pick as stock any of the last 4/5 stock apps on https://setiathome.berkeley.edu/apps.php

https://www.omgubuntu.co.uk/2019/09/raspberry-pi-supercomputer-oracle

The Raspberry Pi is a versatile device adaptable to all sorts of uses — but can it be a super computer too?

Oracle think so, as it’s is showing off a super computer it’s built — baked? — from 1024 Raspberry Pi’s, 49 custom printed Pi holders, 22 network switches, 18 USB power supplies, and lots and lots of wiring.

OK so I got through the work of getting the new Gentoo build for the Pi 4 loaded and running. It took forever to get it installed with BOINC. Could just be because of some of the extra work to get it installed. One thing i noticed after the fact is that it seems to only use the new app compiled just for the AARCH64 kernal. Still letting it run now to see if there is any appreciable improvement in processing. There may or may not be since it looks like the complier didn't apply allot of optimizations.

Good going with the Gentoo on the Pi4!

There's various articles for adding your preferred mix of compiler optimizations into the "/etc/portage/make.conf".

Of the various optimizations, don't overlook the power of using "-Os". That can be surprisingly effective to give a speedup on small cache and/or low memory bandwidth systems.


Happy cool crunchin'!

And the RasPi4 gains further (gaming) support:


Lakka Officially Brings Game Emulation to the Raspberry Pi 4

... Lakka 2.3 comes with plenty of new features—from new emulators (referred to as cores) to a big RetroArch update. The team also promises fancy new notification animations, widgets and other overlays throughout the Lakka interface...



Play on!

Greetings,

Courtesy of a fellow SETIzen, Gary Carpenter, here is some more information concerning the Raspberry Pi 3 B+. I don't know if this works the same for the Pi 4 and Pi 3s manufactured before January 2017 must have a firmware upgrade done for this to work. This is a routine for disabling the WiFi and/or Bluetooth on the Pi 3.

To do this you need to edit the /boot/config.txt file. In terminal type:

sudo nano /boot/config.txt

Scroll to the end of the text in the document, add a blank line after the last line of text and add these 3 lines:

#Uncomment these to enable WiFi and/or Bluetooth
dtoverlay=pi3-disable-wifi
dtoverlay=pi3-disable-bt

Press CTRL+O and hit ENTER then press CTRL+X.

If BOINC is running, shut down BOINC in whatever way is right for the way you have BOINC installed and reboot the Pi. For my installation I used:

sudo /etc/init.d/boinc-client stop
sudo reboot

My reason for doing this was I had eliminated my ethernet router and just used my wireless router with ethernet capability. My Pis showed that they had 2 IP addresses in the connected devices section of the router software and I inadvertently used the wrong IP addresses for remote access and BOINCTasks. Disabling WiFi in the Pi will not show that the Pi has wireless capability and there will only be the wired IP address for the Pi.

I hope this helps out any new (or even old) users of the Raspberry Pi on BOINC/SETI. :)

Have a great day! :)
