The way Einstein source code is organised is a bit different than how it's done here.

Over here, you have complete source tree for stock CPU app. And you have complete source tree for optimised CPU apps. And you have complete source tree for CUDA, OpenCL and CUDA special app, one tree for each.

Einstein's BRP app has only one source tree that includes code for CPU, CUDA and OpenCL.

When you built the app for your Nano you used the CUDA code, not the CPU code.

All the BRP applications are really the same app and the task are the same as well. The tasks that were targeted for GPUs just had multiple tasks bundled together to increase runtime and decrease load on servers.

My Huawei P20 lite is about to get the update to EMUI 9.1 and thus Android 9.0 which will probably mean that at the end of it it will refuse to run Seti tasks. Or has anyone updated from Android 8.0 to 9.0 without trouble with regards to their Seti tasks (SETI@home v8 v8.01
aarch64-android-linux-gnu)?

Edit: at least when it doesn't want to run anymore I have less chance my phone overheats when it's doing navigation for me, in the phone holder on my dashboard, whilst in the full sun and I forgot to turn BOINC off. 😄

I bit the bullet and let the update go through. My phone is super slow now, it probably needs an extra reboot or something. But BOINC and the Seti tasks made it through. They haven't failed yet. 🤞That doesn't happen.

Overclocking the Raspberry Pi 4

The Raspberry Pi 4 single-board computer is, as our review demonstrates, something of a beast relative to its predecessors. But there’s a way to get even more performance out of it -- or any other model of Raspberry Pi, for that matter: boosting the CPU and GPU clock speeds through overclocking...



The Raspberry Pi goes Fourth

My, hasn't it grown. It started as a modest project to get a few thousand children coding but has since become the best-selling computer ever made in the UK.

It is used by schools, hobbyists and in factories - and even turns up as a means of hacking Nasa. And on Monday, seven years after the first one went on sale, Raspberry Pi 4 is launched.

The latest version of the barebones computer is a significant upgrade - three times faster than the Raspberry Pi 3...

... In 2015 the Raspberry Pi foundation merged with Code Club and it now employs more than 100 people, compared with the 50 working on the commercial side.

Mr Upton, who runs the commercial division, is keen to stress that education is still at the heart of the project. "We hope to see the Raspberry Pi 4 in school computer labs, after-school clubs and children's bedrooms across the UK, and indeed the world."...




Good fun stuff!

IT is very much what we make it!

I ordered one earlier this week.
And have to say that it was a easy as anything to get up and running.
Initial problem - it uses a micro HDMI connection, and I only had normal and mini connectors to hand.
Second problem (and this may be a problem with where it is situated) it drops its WiFi connection periodically.

Running "straight out of the box" with whatever o/s came pre-loaded on the SD card (NOOBS?) I grabbed a copy of BOINC from the repository, which loaded very cleanly (installing a few dependencies on the way), the joined SETI and away it went. Running overnight it looked after its self and has completed and returned a handful of tasks. Run times are about a third of a Pi3 with a similar configuration (that is nothing special, and all cores running).

Just an FYI, the Official Raspberry Pi 4 Desktop Kits are back in stock at https://thepihut.com now, I just ordered mine!

Metal Detecting

The kit was out of stock when I ordered, and I (wrongly) thought I had a micro HDMI connector - well I was half right on that, having a micro to micro cables, but not a micro to normal......
I'm going to have to investigate cooling as it runs "screaming hot" - I think I'll go for some sort of framework set up and put a fan blowing across the boards for now. I've just got to find that pile of stand-offs to try that - I have a small fan "in stock" that should do to test.

The description of the kit says it has 2 × micro HDMI to Standard HDMI (A/M) 1m Cables included, so you should be all good!

Metal Detecting

Well the Pi4 has been up and running for a couple of days now, and it is rapidly catching up on the Pi3 sat alongside it.

Two things:
All my stand-offs were 3mm threads or greater, so a minor adjustment had to be made to the boards so they would fit. Not a big issue, but one to be aware of when purchasing generic mounting hardware for the Pi family.
Second, and this one is a little more serious. The Pi4 keeps dropping its WiFi connection, sometimes it comes back by itself, other times it requires a bit of human keyboard prodding to get it to come back to life. This behaviour is unlike the Pi3 sat next to it on the bench which just hags on in there - I've tried swapping the two over on the bench to no avail :-(

I have seen other reports that the Pi4 is prone to dropping its Wi-Fi regularly. So go with the Ethernet connection.

Hi Keith,

I never did try to use my Pis on the WiFi; they are on a switch with my 2 tower PCs. I did find out though that my WiFi router blocked all 3 Pis and I found this out when I could not get connected with my new laptop. It too was blocked by the router. It would connect to the router, but not beyond. I unblocked it, since it doesn't have Ethernet anyway, but I left the Pis blocked. No sense in confusing the issue. ;)

And no, I'm not going to use my new laptop for SETI. I don't think it even has a cooling fan in it. Hmmm... Just had a thought about my old laptop. It does have a fan. Well, I'll think about it... :)

Have a great day! :)

Unfortunately using a wired connection isn't an option where the Pis reside, so I'm going to try a few more locations and see if I can find somewhere better.

From the reviews of the Pi4 it was stated it is not a signal strength problem for the Wi-Fi but rather issues with Wi-Fi radio driver and resource contention.

So with luck a future update should resolve the issue.

That's the gist I got out of the review comment. New Wi-Fi and Ethernet chipset on the Pi4 different enough from previous generations that needs some further debugging.

In my case it might have been a thermal issue - now there is a fan blowing across the surfaces (no additional heatsinks yet) the problem appears to have gone away. At the same time the run-times have dropped a bit.

(Now I've proven the concept of the cooling fan I've just got to tidy everything up so it "looks pretty" rather than a pile of tape and wires...)

Is there a Raspberry Pi-like SOC with a standard pcie slot (and/or addon kit)?

If I get started on this experiment I really want to be able to drop a gtx 750ti or gtx 1060 3GB in there.

I had researched/stumbled on this request once before. The one that jumps out is the Pine64 RockPro64 SBC with X4 PCIe slot.
