1) Message boards : Number crunching : Problems and Technical Issues with Rosetta@home (Message 113045) Posted 29 Aug 2025 by JLDun Post: its because theres no aarch64/ARM64 build and it seems that newer Android versions will crash/error All of my hosts, such as 6286328 (Android 12), report "ABI: arm64-v8a" to the projects (as registered by BOINC); CPU-z reports aarch64. I do agree, though that there will be some difference between each OS version; in practice it appears to result in my Android 9 and Android 12 devices being the only ones to currently return any valid work
2) Message boards : Number crunching : Problems and Technical Issues with Rosetta@home (Message 113022) Posted 21 Aug 2025 by JLDun Post: I was lucky enough to download 17 tasks from the recent batch last night, but 8 of them crashed within 3 seconds, all with "process exited with code 2 (0x2, -254)" and "no such file or directory". The only noticable difference (on my end) is the ones that crashed were on an Android 15 phone and tablet, and the ones that are still running are on Android 12 & 9 phones. (EDIT: This is with the default/manufacturer-installed OS on each one.)

5) Message boards : Number crunching : Problems and Technical Issues with Rosetta@home (Message 110073) Posted 26 Nov 2024 by JLDun Post: I was getting "transient" errors yesterday (on a phone, using Google Fiber for WiFi).
6) Message boards : Number crunching : Unable to download data files (Message 110027) Posted 14 Nov 2024 by JLDun Post: Two other reports of transient HTTP errors in the "Problems and Technical Issues with Rosetta@home" thread. Still no such issues on my systems. Maybe contact & compare ISPs and geographic location with those others that are reporting such issues? Admittedly, I didn't think of a Trace, but I was one of the "Transient" reporters (and eventually got the files to download). Located in Missouri, USA; Google Fiber 300 Mbps (and trying to download onto two different Android devices).
7) Message boards : Number crunching : Problems and Technical Issues with Rosetta@home (Message 109999) Posted 8 Nov 2024 by JLDun Post: Getting some "transient https errors" in attempting to download some tasks.
8) Message boards : Number crunching : Rosetta needs 6675.72 MB RAM: is the restriction really needed? (Message 101717) Posted 3 May 2021 by JLDun Post: Host 6057423 Mon May 03 12:09:16 CDT 2021\|Rosetta@home\|Message from server: Rosetta needs 1386.40MB more disk space.

9) Message boards : Number crunching : Only great jobs available using more than 3GB memory ? (Message 101691) Posted 2 May 2021 by JLDun Post: I had just checked; nothing for an Android 9. (Given that Android did have a separate listing until recently for WU's split, and I had received one after the recent change to combine the listings, yes it is hard to tell anymore.) Edit:And then I check again after posting, and get a task. (Dont know if I could have received more; settings were along the lines of {Run 2 CPU's, 1 different task already running}.)
