I just wanted my single Pi to be kept busy because the cost in leaving it on 24/7 is not insignificant to me. There are some people here with multiple monsters processing work units. My solitary Pi was never going to make a dent on their requirements so please do not think badly of me for trying to cache enough to to keep it busy for a couple of days. I will complete the units currently being processed but suspect that this project is not for me. I have aborted my cached units back into the pool.

Hopefully without sounding disrespectful to Balena I do not think they are going to make any changes to how their client works any time soon for a number of reasons, not least with getting other projects on board and comitting time and resources to making someone else's project compatible. On a slightly different note, at the time of writing this the server status as reported on the website appears to be OK but my rig is reporting internet connectivity but no response from the servers again. Ho hum.

4) Message boards : Number crunching : Problems and Technical Issues with Rosetta@home (Message 100956) Posted 1 Apr 2021 by Garry Heather Post: Regarding my 2 day cache, I do not consider that excessive given that my £35 SBC running off an SD card (OK, it's an SSD now but when I started it was an SD card) has a more reliable uptime than the servers running the project. In the time I've been doing work for Rosetta I have seen several periods of downtime where work units have not been deployed for days at a time. I don't mind having a Pi dedicated to the task so long as it's doing real work and not just heating the room. I also get the idea of other projects and I looked into it, however my current setup is severely restricted in that department. I am currently using the Balena client image mostly out of convenience and I have not found another project compatible with that and my processor architecture. At the moment I haven't got the time to go digging around in Linux trying to make this work as I'm still very much learning. I know enough to be dangerous but even online guides tend to make assumptions about people's prior knowledge that are a considerable block to entry.
5) Message boards : Number crunching : Problems and Technical Issues with Rosetta@home (Message 100914) Posted 31 Mar 2021 by Garry Heather Post: It is interesting to read how this is affecting other people - my Pi 4 rig I mentioned previously had acquired a cache of 2 days worth of units but has since stopped downloading more due to the insufficient memory issue. I do rather hope that this is not going to become the new normal.
6) Message boards : Number crunching : Problems and Technical Issues with Rosetta@home (Message 100890) Posted 30 Mar 2021 by Garry Heather Post: My Pi 4 rig that was in difficulty earlier seems to have sorted itself out although it did experience a number of download errors beforehand. I've now got a cache of 2 days work so unless a number of those abort I should be OK while everything stabilises again.
7) Message boards : Number crunching : Problems and Technical Issues with Rosetta@home (Message 100882) Posted 30 Mar 2021 by Garry Heather Post: OK, my Pi knows I am talking about it and has subsequently acquired more work units. The error message relating to insufficient memory persists however, so I have referred this to Balena in case it is an update with their client that has introduced it.
8) Message boards : Number crunching : Problems and Technical Issues with Rosetta@home (Message 100881) Posted 30 Mar 2021 by Garry Heather Post: My Pi has collected one unit (I would have expected about 8) within the past 20 minutes but the error concerning memory remains.
9) Message boards : Number crunching : Problems and Technical Issues with Rosetta@home (Message 100878) Posted 30 Mar 2021 by Garry Heather Post: I am using a 4GB Pi 4 purely for Rosetta and have today started getting error messages relating to insufficient memory. It's been working fine up until today if I exclude it running out of work units overnight. Message from server: Rosetta needs 6675.72MB RAM but only 3653.61MB is available for use. I am aware that there appears to a lull of new work units but the sudden appearance of additional memory demands is of greater interest. I hope this is not going to render the smaller boxes such as the Pi's obsolete.
