In the past i was skeptical to crunch Rosetta on old versions of Raspberry.
Now this version has so much new features like new cpu (from 40nm to 28nm), new ram (from LPDDR2 to LPDDR4), Gigabit Ethernet, USB3, etc, that may be interesting to use it on this project.
It's a pity there are not wus for Android for a long time

---

I agree. The 3 was pretty good and there's some good competitors, but the 4's better CPU and optional 4GB of memory really makes a big difference. I really wish Rosetta could leverage all the ARM products that are available today and going forward.

---

Any word of a version of rosy for the Pi 4? I could see a whole stack of these at my house. 4 cores at 15W sounds good. Could we get the Android workloads to run on this thing?

---

Thx!

Could we get the Android workloads to run on this thing?

In the old version of Raspberry it's possible to run Windows 10 IoT, Linux and....Android.
I think will be possibile even with this version

---

I look forward to some benchmarks on this platform with Rosy. I can buy lots of cores with obsolete AMD Opterons at about 550 RAC per core. A machine with 64 cores & 64GB RAM costs about $300 & yield a RAC of 35,000. It would require 16 Raspberry Pi 4B machines for the same number of CPU cores and RAM. The Pi solution requires much less power but would cost almost 3x as much.

I look forward to some test runs on this platform.

Thx!

The Pi solution requires much less power but would cost almost 3x as much.

You are comparing a server cpu with an all-in-one card, it's obvious that IPC is on the Opteron side.
But the TPD of 64 cores machine? How much watt per day??
I think that, after a couple of mounth, Raspberry is convenient.
Obviously, the management/maintenance of 16 Rasp is much more demanding that a single workstation.

Interesting guide for Boinc on Rasp4

Cut the price

it’s our eighth birthday, and falling RAM prices have allowed us to cut the price of the 2GB Raspberry Pi 4 to $35

I tested BOINC on Ubuntu 19.10.1 on an RPI 4 today. No Rosetta@home work units available, though.

First, install 64-bit Ubuntu 19.10.1 on the RPi 4. arm64 is also known as aarch64 and armv8.
https://wiki.ubuntu.com/ARM/RaspberryPi#arm64

Then, install docker.
https://docs.docker.com/install/linux/docker-ce/ubuntu/#set-up-the-repository
Note that at the time of writing, one must modify step 4. Change the arch and branch such that it reads: "deb [arch=arm64] https://download.docker.com/linux/ubuntu eoan test"

Next... well, that's it. Bootstrap boinc and attach it to rosetta via:

docker run -d --rm --name boinc_rosetta -v /data/boinc_rosetta/:/var/lib/boinc boinc/client:arm64v8
docker exec boinc_rosetta --project_attach https://boinc.bakerlab.org/rosetta/ USERKEYHERE

Unfortunately, there's no work items for the detected OS string:

https://boinc.bakerlab.org/rosetta/apps.php doesn't have an entry configured for aarch64-unknown-linux-gnu, but you do have one for android arm. Trying to ask for those as it should be compatible. Ensure the cc_config.xml looks similar to the following:

/data/boinc_rosetta/cc_config.xml

<cc_config>
<options>
<alt_platform>arm-android-linux-gnu</alt_platform>

No projects sent tonight. Checking the status page, no arm tasks at all are active now: https://boinc.bakerlab.org/rosetta/server_status.php.

----> Asks to the Rosetta folks: please cut a few aarch64-unknown-linux-gnu tasks for folks to use.

I tested BOINC on Ubuntu 19.10.1 on an RPI 4 today. No Rosetta@home work units available, though.

You can crunch on Tn-Grid

Is there any rosetta application to run on raspberry pi? Will be in the future?

Thanks! Seems to be working great on two RasPi A rev 2 and one RasPi B rev 2. Memory footprint is surprisingly small for the first tasks I received, under 40MB working set size.

Is there any rosetta application to run on raspberry pi? Will be in the future?

Same question on Twitter, R@H account replied:

We've got an update on that coming soon. Stay tuned!

Same question on Twitter, R@H account replied

Yep, nice. Here's the tweet.

I hope this includes a smaller memory footprint as well. I have five RPi Compute Module 3s arriving in a few days, and would love to dedicate them to R@h.
After OS overhead, each of the 4 cores will have 240MB or so of RAM (assuming GPU will not be used).

Hi,

i saw there is a new version "Linux running on 64-bit ARM V 4.12" from 01.04.

I've added Rosetta to my RasPi 4 with "buster", but i always get a message like:
"03.04.2020 10:50:44 | Rosetta@home | Message from server: This project dont support computers of type arm-unknown-linux-gnueabihf" (translated from german...)

Is the "Linux running on 64-bit ARM" not for the Raspi 4 ?

You need to set the Pi4 kernel to 64 bit. By default its in armhf mode for compatibility with the older Pi apps. Once you've done it then it will say its aarch64 (which is ARM64). You'll be able to run aarch64 apps but there are a lot of compatibility issues with older apps.

See MarksRpiCluster for instructions.

After that to get BOINC to think its an aarch64 version you need to add an alt_platform entry in cc_config.xml within the options tags. It would say:
<alt_platform>aarch64-unknown-linux-gnu</alt_platform>

Also be aware the Covid-19 tasks can use up 1.5GB of memory so you might need to limit how many you run at a time.

Thanks a lot, Markj !

I'm running the "new" kernel now : Kernel version: Linux 4.19.97-v8+ aarch64

But... : I still get the same error-message and no work ! :-(
