I can't find any way to run Rosetta@home on Rasperry Pi 4 (4GB RAM).
All Ubuntu images (said can use 4GB RAM required to run Rosetta@home properly) says works but just don't work.

Have you tried Raspbian or do you want to stick with Ubuntu?

If you want to try Raspbian I have instructions on how to get it into aarch64 mode and BOINC going here:

Thanks a lot, PorkyPies

Raspbian of course have no Ubuntu above issues. I followed instruction (64bit related) on your link and all looks good for the moment. Just have to wait due communication deferred for 24 hours on boinc but anyway looks better than using Ubuntu images.

Thanks again.

Tried ( ref: https://www.tomshardware.com/how-to/fight-coronavirus-with-raspberry-pi ):
https://www.raspberrypi.org/downloads/ ( Ubuntu 19.0.1, 20.04 beta ; 64bit )
https://ubuntu.com/download/raspberry-pi ( Ubuntu 19.10 ; 64 bit )
Mainly problems (just can't boot and enter to the console or whatever gui):
- network interfaces not found
- keyboards not found
It's not about SDCARD content, EEPROM or USB, all ok with these; other RPI images works well but not applicable to Rosetta@home.
Any help appreciated.

Hi especially @Grant (SSSF)

Where I am wrong?
I need 2x more time to finish the tasks and 50% GFLOPS on similar i7-8700K CPU

Compare:
- https://boinc.bakerlab.org/rosetta/host_app_versions.php?hostid=3933928
- https://boinc.bakerlab.org/rosetta/host_app_versions.php?hostid=3914491

Thanks in advance.

Thanks a lot, Robert

I changed all to use 99% of RAM (was 90% as default and 50% for other). And 1% of swap.
It looks no out of memory errors for now but memory usage stay as before.

For 12 tasks, the total memory usage is about 6GB. It looks R@H using less memory per task than max available for 32bit app.

Here is a task with max mem usage:

Application Rosetta 4.12 
Name 4dy3ga3h_jhr_design1_COVID-19_SAVE_ALL_OUT_903392_1
State Running
Received 2020-04-01 21:33:01
Report deadline 2020-04-09 21:33:00
Estimated computation size 80,000 GFLOPs
CPU time 08:11:40
CPU time since checkpoint 00:04:37
Elapsed time 15:34:17
Estimated time remaining 2d 05:56:33
Fraction done 22.400%
Virtual memory size 1.12 GB
Working set size 1.14 GB
Directory slots/2
Process ID 14460
Progress rate 2.520% per hour
Executable rosetta_4.12_windows_intelx86.exe


Btw a task take about 2-3 days to finish, from an initial 4 hours estimation; it's that normal?

I have 2 tasks with Computation error resolution:

https://boinc.bakerlab.org/rosetta/result.php?resultid=1136321350
https://boinc.bakerlab.org/rosetta/result.php?resultid=1136320461

Both looks receiving out of memory at a point.
I have 64GB RAM; it's about Rosetta@home on 32bit or something?

Thanks,
Iulian

Use the anonymous platform support or a 32 bit BOINC.


How to exactly I can do this?

I run into setiathome using anonymous platform app downloaded from http://lunatics.at/index.php?module=Downloads;catd=1

Where I can find similar one ready to download for rosetta?

Thanks
