This is still not available. I don't want any minis so I'll have to abort them.


Hello, are you sure ??? Still not available !?!?!? It was available. Not more for new users
Yes this option is available. But I agree, very difficult to find it. It is not clear explained.
By the way, with your about six hundreds cores what a difference ?

It sounds like the bottom line here is that there are presently some work units that are using excessive memory. These are reported in several other threads. So this would mean your low-memory system did not happen to get any of these, or perhaps they are flagged to only be sent to systems with large memory.

This sometimes happens when the Project Team is working on new protocols. And it is generally resolved within a few days.



Mod_sense

Oups,
Additional info to my previous message.
As team founder (wide team, in Berkeley sense ) , I centralize all problems, questions of my team and on all projects.
It is perhaps why some users consider me as the "black sheep of boinc" ...
It not hurt me. I (and our team) want to help evolution of research.

So

One of my user with 64Gb RAM (sixty-four) and 8 cores, reports the same problem of "not enough memory) !!!

I think with 64Gb RAM, it is enough. But it also crashes !
Sorry if I repeat, with simultanous WU with only 8Gb RAM is OK on my host
More RAM, ...

If it crashs at beginning, not very worst. But always after some hours !!!

Or perhaps a serie of WU with problems.
Please analyze host 3391074. You have access.
I got 35 new WU on 11aug19:08 UTC. I stop all other PRJ. To give full ressources. We shall see
Only PrimeGrid run GPU (RAM use 300Mb) CPU 0.09
So after five minutes start of 8 Rosetta : RAM ; 70% free (from 16Gb)
Normally no problems.
Estimated running 7 hours. But I never look it. It is Windows estimation.

I stop to write. I wait action, explanation .

Best reagards

Hello Mod_sense.
Instead to stop reading after the first line, If you had read the next line, It is SIXTEEN gigabyte available.
Not two gigabyte.
If you had took the time to analyze, my hosts ...

So, Please understand very good and read all very good !!!
On two of my host with 16Gb, all crashs with error "not enough ram".

As stpudid and because I want to understand, on those host I removed 8Gb RAM.
Who will do a downgrade of RAM ???

But now, with only 8Gb no problem !!!
I added again 8Gb (again crash, and not the same RAM)

Where is the problem ??? I am HW scientist, not SW developper.
But once again, I want to understand.
A bottlezneck on CPU northbridge was possible due to CAS and LAT time.
But it is not

Your WU says on 16Gb RAM : not enough. With only two running WU !
But with only 8Gb , all OK with 8 (eight) simultanous WU !?!?

Waiting explanation, and solution,
Best regards

The only recent (16july19 by admin) is about "audacious projects". Nice, but is not a part of Boinc.

It is fabulous news, and great for Rosetta.
I think it is entirely possible that Rosetta is now the most important BOINC project there is.


As you may have heard, the Institute for Protein Design was recently selected as part of The Audacious Project. This large-scale philanthropic collaboration, which is the successor to the TED Prize, surfaces and funds projects with the potential to change the world.

As a result, we are expanding our Seattle-based team of scientists and engineers who will work together to advance Rosetta, our software for protein design and structure prediction. The funding will also allow us to invest in the equipment, supplies and lab space needed to design and test millions of synthetic proteins.

Hello Jim,
Roseta is one of Boinc PRJ, not "the" Boinc" PRJ !
Of course more usefull for Mankind that some other projects.
Climate, is also usefull .
Physics of particules, also, ......
All are important and make a "global" knownledge. All in paralel, not seperately.
Why to give full priority to proteins, if we are unable to fully decode genome ?

Only one "enormous" example : we discover some new proteins, nice. Nobel price.
But later, because we do not know fully genome, we discover that this new protein is toxic...
So, Roseta is not the most important ! .

It is simple to understand, some (many) of the current robetta_08_07_xxx wu use 2 GB RAM or above. if your are "lucky" enough to process simultaneously 8 of them you will be over your 16 GB and even if boinc is configured to use no more than 95% of your available memory, you will experience slowdown and most probably wu crash or host crash or both. It is quite known problem here, investigators not always fix correctly the wu memory requirements, they are also human after all.

It has just happened to me both in a host with 64GB but with 72 threads and another one with 124GB and 112 threads. So, I've set to use the 50% of CPUs while the storm goes way :).





Hello Trotador.

Before posting, I tested with only one WU and no any other PRJ.
I repeat only one WU, with 16Gb RAM. But crashed with error not enough memory !
Stderr.txt write mem peak use 2.5Gb (2500Mb) , I have 16Gb, but exit code : not enough mem !

Hello Mod.Sense
As admin you can see all. You have my host ID, WU ID !!!
So you can look the stderr.txt and reason of crash.
You can see that host have 16Gb RAM,
But WU sas at around 9Gb ; not ram enough !!!

Most stranege I have a other host ( with only 8Gb RAM host 3676676) and no problem !!!!

To be clear but fully understable ;
16 Gb RAM , Crash because not enough RAM
8 Gb RAM all OK

I want to understand !

Sorry, I leave this projet.
Admin publish information as links. Nice to be informed about . The latest is three years old !!!
The only recent (16july19 by admin) is about "audacious projects". Nice, but is not a part of Boinc.
And this link send us to donation requests !

And about projects who has nothing to do with sciencetific research, as educating people, sexual abuse,...
Of course there are also very important subjects, but
Does we think they not need the computing power of Boinc ?

But what they do to solve the problems of a lot of users ? Abnormal running, app crash,......
Nothing ! Or even good as nothing.Never answer about technical problems. The admin fully ignare the Boinc cruncher.
They just ignore us !

Hello,
after about two hours : "computation error"
Reason : out of memory !
By looking stderr, the peak is about 1.5Gb
Considering I run 8 WU and I have 16Gb RAM, who can explain ?
See host https://boinc.bakerlab.org/rosetta/results.php?hostid=3660644

Hello LINK;
Thank you for response
But it not answer about why we can not more select apps !

perhaps I not post my question on the right place

Hello,
A long time ago, it was possible to select Rosetta or Rosetta Mini.
But now in preferences, it is not more visible !

I7-2600K - 16Gb - Win7 Ultimate x64

How to get only the "mini" ?

Best regards
