Hello to the community.

I am a BOINC member and I am participating in ROSETTA@Home project. The last two days I am dealing with an issue when working on ROSETTA projects.
I finished the projects and I come up with a ‘’computation error’’. I have complete three project the last two days
and two of them ended with a ‘’computation error”
Please check link https://boinc.bakerlab.org/rosetta/results.php?hostid=3813606
Is it an issue with PC specs or an issue with the projects?

Check the BOINC Manager Event log for messages relating to disk space. Do you have a AV or Internet Security programme on that system, as many of them need to be told directly that BOINC and it's subfolders are not malicious.
1 Task you aborted, the others had file problems-

No AV or Internet security. I use Linux Mint and I haven't installed anything besides what it comes with linux distro.
I have enough space on hard drive (items 30.0 GB / Free space 44.4 GB). I have already completed some Rosetta tasks and other BOINC tasks without any problem.
Check Event Log, I didn't find anything maybe because I restarted my PC...

P.S. I also saw that some other LINUX PCs had similar "computation errors".
Is there a chance for faults/ corrupted projects maybe?

Do you have a HDD or an SSD? If it's a HDD, can you give the drive more RAM for write caching?
Rosetta writes a lot of data at various points throughout processing a Task. Even current HDDs shouldn't have any issues, but the errors you've got there point to either AV software (which you don't have) or storage I/O problems, and that is an older, slower, limited core system.

Check Event Log, I didn't find anything maybe because I restarted my PC...

Yep, restarting BOINC clears it's event log (maybe just exiting does it, i've never actually checked that).

Always possible, but unlikely.

I can't see any issues with your Computing preferences, although if trying to reduce system temperatures due to cooling issues i'd suggest swapping those values around (maybe having to change the 85 to 50 to free up the other core)- gnerally it's better just to have less tasks running all the time, than more Tasks running and starting & stopping them. It may be involved with your issue- low powered system dealing with periods of very heavy disk I/O.
Even so, the stock heatsink & fan on the Core2 Duo as long as they are both nice & clean & the case vents & fan(s) are clean shouldn't have any heat issues running both cores at 100%

PC Specs (it's pretty old):
Intel(R) Core(TM)2 CPU 6400 @ 2.13GHz [Family 6 Model 15 Stepping 6]
RAM: 4GB (BOINC uses 75%-85%)
OS: Linux Mint Tricia 19.3 (32-bit).
DISK: HDD (western digital)
TEMP: Pretty much is fine (around 77 Celsius if I have more than one task at the same time or around 72 Celsius if I have only one task)
(Nothing else runs besides the BOINC projects. I have this PC only for that job)

I really don't proceed to multi-tasks, especially if projects are more than 10 hours.
I usually start 1-2 projects (or 3 if some BOINC projects are up to 3 hours).
CPU to 85% runs pretty well to other BOINC projects

Anyway, I already have two more tasks in queue, so I will test again and also copy the events from BOINC event log

Seems this one worked well. I really can't understand why the other two tasks ended with "computation errors", since I didn't change anything.

I wouldn't worry too much about it on your end. New application version, bugs shaking out. New 4.13 version on Ralph now for testing.

I can understand that a new project/ software will probably have some kind of bugs.
The sad/ frustrating thing about Rosetta projects is that they are time consuming and the last thing you want to see after 8-12 hours of work is these kind of errors.
At least, I hope they can extract some info, despite of these computation errors.
