1) Message boards : Questions : Getting work on Arm64 CPU (Message 892)
Posted 22 Nov 2021 by SU-Worker
Post:
I have 64bit Ubuntu Server 20.04 LTS running on a Raspberry Pi 3B+ and I am very sure that my configuration of BOINC on it is fine. What I am unsure of is why it is not doing any work? I have a Raspberry Pi 2 running 32bit Ubuntu Server 20.04 LTS and it is doing work fyi.


I have exactly same issue with a debian 64bit on arm64 architecture.
My servers got several jobs up to few weeks ago. Now they are not getting anything.
Preferences on projects didn't change on my side. I can imagine some project could have no work
but based on what I see on "how work is assigned to your computer" page, they should have quite
a big amount.
2) Message boards : Suggestions : Meaningful description (Message 876)

Despite not all contributors (me included) could fully understand detailed explanations on tasks,
it could be interesting to get at least a meaningful description of what a task is calculating.
In that way we could really know what our computers are contributing for.
The task name is most of the time non-sense for everybody else than the developer itself.
Further, several projects span on multiple scientific areas (Rosetta for instance)
and tasks names are not meaningful at all.
Something as World Computing Grid does could be enough.

Hello,

Based on my preferences, I should get lot of works from following projects:

LHC@home 4 0 999.882 1,003.882 yes
RNA World 3 0 999.999 1,002.999 yes
Climateprediction.net 3 0 999.977 1,002.977 yes

LHC@home has been providing tasks since few days ago (I guess I contributed with about 116 jobs).
But now, non of them is providing any task.

Any hint/help, please?

Thanks in advance.
4) Message boards : Questions : How do I block a *specific* project? (Message 864)
Posted 17 Oct 2021 by SU-Worker
Post:
I've done this in the past for Cosmology@Home, which (at the time) would block all cores/threads of my CPU and not actually compute (really, Task Manager would report 0% CPU used, or near to it). Maybe that's been fixed, maybe it hasn't, but whatever.

I want to block Amicable Numbers because it posts a bazillion tasks that use all 36 CPUs (yeah, I'm rich, I can afford an i9 10980XE), and therefore blocks all other tasks (which isn't very amicable...) (sorry).

However, I don't want to block *other* mathematics projects, so I can't just block mathematics in general.

So how do I mark Amicable as "excluded"? (And how do I unmark Cosmology to see if they've fixed the problem?)



I have a similar issue with Rosetta@home whose tasks reset to "0% done" each time I stop and restart my computers, resulting in huge amount of wasted CPU time.
I just found a way to exclude it:
From User home page select "Scientific Porjects"
then select the project you want to exclude from the shown list.
The details page shows.
Look foor the last option. It is "Exclude"
5) Message boards : Problems : Rosetta@home tasks reset to zero after reboot (Message 863)

Hello,

I got two new tasks from Rosetta that seem to not have checkpoints enabled: I left them running up to about 25%, then I had to switch off my server
and after it was switched on again I could see those tasks were reset to 0% done.
They have similar name than others previously processed that I am almost sure were not having this issue, so I suppose these specific two are some way "defective".
Running to completion in one shot those tasks requires about 9h of elapsed and now I am at risk to break their deadline. Therefore I will probably have
to abort them after have spent already more than 5h CPU time (3+ hours first run and 2+ hours this second run).
Is there a way to report this kind of "malfunctions" to the project?
Otherwise, if that task behavior is expected by desing for that project, I would like to raise that, in my opinion, it is not fair to force contributors
to run tasks for so long time in a row.


Hello,

just to provide more details:
all Rosetta task with name similar to (numbers may vary)
rb_10_15_140181_136445_ab_t000__robetta_cstwr_5.0_FT_IGNORE_THE_REST_03_10_2093785_210_0
do not save the status in case the computer running them is rebooted. If that happens they are reset to zero.
This force the contributor to keep them running for the required 9h in a row. Aborting them results of course in
"failed tasks" into statistics.
Since most part of tasks I receive from Rosetta seems to be of this type, I am wondering if I would be better to
unsubscribe the project. I don't like the idea to do that but I don't see other options (I don't want to leave my computers
running continuously for 9h).
Any hint?
I am surprised nobody else is affected by this issue. Maybe everybody is running them on cpus that much faster than mines
that they don't realize there is this issue?
