Message 83087 - Posted: 14 Aug 2014, 0:00:00 UTC

Due to user feedback and an attempt to reduce the load on our servers, we increased the default target run time from 3 to 6 hours, increased job deadlines to 14 days, and added the target cpu runtime option of 2 days. Any input on this is appreciated, good or bad. Please post to this thread. We can revert to the previous values if necessary after assessing how these changes effect the project. Remember, you can always set the run time preference to your liking, from as low as 1 hr to as long as 2 days. It is the "Target CPU run time" option in the Rosetta@home specific preferences. Also keep in mind that it's a target run time but if the job is a large protein, it may take longer than 1 hour to generate 1 model so the actual run time can exceed the target run time (at least 1 model is generated).

hmm too bad. means people need to have 24/7 machines. i just tested rosetta the last few days and it gets now only 5% of resources.
Reasons:
- Too low deadlines (and my cpu time for you is for nothing when the time excceed the deadline? too bad! no, this is not the deal to offer free cpu time and the project dosnt make sense then)
- To much disk usage/ Smaller chuncks needed (not possible?)
Boinc gets ONLY 3-5GB diskspace. This means it blocks other jobs (like seti) beeing loaded even if 10/12 cores are iddle. they are block by diskspace until one of ~4 rosetta jobs is done to free diskspace.
- Note: Only once a day (for 1h) networking is activ. You should calculate how many jobs can be done during the next 24h but: Keep in mind that jobs can iddle for some few weeks because the cpu power is needed by owner. (seti seems to handle this with my setup/setting with enough time buffer to get the jobs done for sure.

J'aimerais savoir si c’est possible d'assigné plusieurs core sur la même tâches.
La vitesse de travaux fini en temps réel serais maximisé.


Pour les tâches non complet ( il devrais avoir une sauvegarde ) au lieu de perdre l'énergie investie sur les death line.

Message 99406 - Posted: 26 Oct 2020, 15:46:18 UTC

An observation I have made bothered me. I understand the program generates a random start point, then runs the model to completion. If there is sufficient time left, now knowing the time the model takes on that node, it generates a new random start point and runs again to completion, repeating this until the run time is reached, or at least, running it again would excede the allowed run time. My observation was that if a run of the model fails, ALL the work done in that run is discarded, including, obviously, the earlier, sucessful runs.

Please note that this thread is six years old and the announcement in the OP is no longer applicable. As of mid-⁠2020, default run time is 8 hours, deadlines are 3 days, and the longest run time option is 1½ days.

It’s been a long time since secondary-school French, but if I’ve understood your question correctly:
I would like to know whether it’s possible to assigned multiple core to the same tasks

the answer is no: all Rosetta@home tasks are single-threaded. Rosetta makes use of multi-core CPUs by running multiple independent tasks in parallel. Furthermore, Rosetta tasks run for a fixed duration; they are not seeking to complete a fixed quantity of work in the shortest time possible. Given that a batch of work consists of hundreds of thousands of tasks, minimising the wall time required to complete a single one is not a priority – and a single-threaded implementation is far easier for the programmers to understand and debug.

If you want computing in 2 core then you need to go inside of the boinc manager and put the number of processors to 50%
te reason is that you are then running on the full core and not on the thread
You are solving in 28000 of second mid computing time with I7 7700

The computing time won't change since it's a fixed runtime based on whatever your preference is on the preferences page.
What will probably happen is that more models are completed within the same runtime (8 hours in your case) since you are using just the cores that are somewhat faster than running all 8 threads.

Hmm, he mentioned an I7-7700 which is a 4C/8T CPU which is on the list: https://boinc.bakerlab.org/rosetta/hosts_user.php?userid=2296186

Your link is not from the same user but rather from another user up on this page :)

Indeed. But maya2 was replying to me replying to lw elite, for whom advice to reduce to 50% of CPUs would be inappropriate.
Maybe something got lost in translation. They could just cut out the middle man, and speak to each other in French… :-⁠)
(FWIW I tried restricting to 50% of my Hyper-Threaded CPUs a while ago; I didn’t record the results but IIRC I got about 80% more credits per task.)

I will stop to run Rosetta I am running it since years but unfortunately I have really big issues to deliver any working unit now due to the little time aloted for us to do the computing. I am running multiple projects and can't abrely deliver any roseta in time. It is annoying to get a unit at 70% and to see that you can't deliver it in the few hours left still available to deliver it. If you can give us a few weeks to deliver a unit like ofther projects I might come back. Sorry about that but tired of loosing computer power for a unit that wont be use at the end.

I keep the default buffer of 0.1+0.5 days (sometimes 0.25+0.5 days when running other long projects) and don't see the problem.
I get the occasional high priority, but they complete on time. I have added several big machines recently (Ryzen 3900X, 3950X), and might do a bit more.

EDIT: Yes, they run 24/7. You need that for Rosetta now.

The other option is to change the Target CPU time to a value less than 8 hours and run with no cache.
