Is Rosetta@Home something that would work within the limitations of quantum computing? I imagine that if quantum computing is as good as it is cracked up to be, it could obsolete the current rosetta@home network and beyond.

I noticed that nvidia is selling a 1U rack mount server that packs 4 terraflops of computing power, and iirc sells for around $8000 each. I suppose this may be a better investment than purchasing many \"traditional\" servers. you need CUDA enabled applications to use it.

If rosetta were to support CUDA, buying this 1 terraflop beast would be in the realm of possibility:

...Leave people alone and let them make whatever choices they want without solicitation.
wheres the problem? i just said \"what about getting some volunteers back\", not about being \"aggressive at solicing support\". if you dont like the idea, say that, but dont become unobjective.

I\'m being quite objective and giving one point of view that you don\'t like. Seeking new participants is appropriate but attempting to re-activate (nag) previous participants who have consciously decided NOT to participate can/will be viewed as intruding into one\'s personal affairs. I would consider this an insult to my intelligence and freedom of action and may in fact be why a previous attempt to solicit participants was met with a cool response.


I support a one-time reminder per person. just a friendly reminder that we\'re still alive and kicking. maybe consider a newsletter subscription as an alternative.
6) Message boards : Number crunching : Running Ralph + Rosetta (Message 58028)
Posted 19 Dec 2008 by Profile Stephen
Post:
Perhaps in preferences you could set your resource share for Rosetta to 1 and leave that for Ralph at 100.


...that would have been my suggestion as well.

How long has this been going on? Which BOINC version are you running? How many days of work are you asking BOINC to keep on hand? Are these the only two projects you are attached to?

I see a large pile of tasks \"aborted by user\". Was that due to resetting the project?



running BOINC 6.4.5, latest as of today. it looks like the resource share is the maximum quota.

the tasks were aborted to put ralph WUs on priority, which have very short deadlines.

a WU will get to around 85% complete , progress will stay the same. time to completion stays around 10 minutes. i suspend all tasks, resume then the \"stuck\" WUs will complete.

edited: doing this also rolls back the \"cpu time spent\" to around 30 minutes

Post:
I currently set Ralph to \"100\" and Rosetta as \"1\". of my 8 cpus, 4 are being used by Ralph, and one is working on Rosetta. I\'m not sure what the deal with the other 3 processors is. BOINC is requested zero seconds of work whenever I try to \"update\" the project. Ralph won\'t download any more WU because there aren\'t any left on the server for now, but I don\'t understand why Rosetta isn\'t requesting any more work.

if I set it to 50/50, on 8 cpus, ralph and rosetta will not get any more than 4 cpus each even if the other project has no WUs available.

Post:
If I have any Ralph work units available, I\'d rather spend 100% of all my available cpus and time to exclusively run Ralph WUs.

When there are no Ralph work units, I\'d like to run all available processors for Rosetta.

Is this kind of behavior I described even possible with BOINC?
10) Questions and Answers : Wish list : regarding partial work units (Message 58016)
Posted 18 Dec 2008 by Profile Stephen
Post:
BOINC attempts to avoid that situation by scheduling the task to run at \"high priority\" when the deadline approaches. This helps improve the odds that it will complete in time. Rosetta extended the deadline to 10 days (used to be 7 days).

For most BOINC projects, a partially completed task is not useful.

No, it will not automatically abort it. Last I knew, it will continue to work on it past the deadline and report it back when it completes. You often will receive no credit for tasks returned after the deadline.

If you have other tasks behind it that are past their deadlines, but have not begun computing yet, I\'d definitely abort them.


auto-abort the expired tasks before they start. i think that would be a good feature for BOINC. at least if you turn in after deadline the work is used for the science but without the credit?

Post:
lets say you are about 90% done with a work unit and the report deadline is about to be reached. does BOINC automatically abort and upload the partially completed WU? it seems like it would be a shame to lose that much work.

I like this idea. But you only gets so many chances to do this and you need to get the message right the first time.

hello,


im sorry if this is not the right place to ask this... so please tell me if this is the case, ill do it better the next time :)

now the question: are there any efforts in reviving old users with have a average credit below lets say 20? or simply users who didnt get credits for the last 2 or 3 months. its obvious that those users dont help rosetta anymore....

i thought of a email to those users, like this:


dear cruncher,

we noticed that you werent active at rosetta for 2/3 month. its very unfortunate that you blah it would be apreciated if you blah would help again blah and so on.



but you shouldnt write blah in the mail :)

maybe you could add something like \"many things have changed, rosetta is improved with everey new version so if you ended helping rosetta because of failing WUs you could try again\"

in short many things have changed, your reasons to end may be outdated.



im sorry if those mails are already automatically written...



johannes


edit: i think this could be helpful for users who actually want to help but simply forgot to install boinc after a reinstallation of the OS/ a new computer or whatever. or if you paused boinc and simply forgot to reactivate it :) this happend to me a few times, but i noticed it the next day....

I\'m running vista64. I am running BOINC 64-bit edition. boincmgr.exe and boinctray.exe are running in 64-bit mode. however, minirosetta_1.47_windows_x86_64.exe is currently running in 32 bit mode. it says *32 next to the name, which I belive to indicate that it is running in 32-bit mode.

Like some other people mentioned, the WU titled

\"cs_noe_fullw_nolin_homo_bench_cs_noe_abrelax_cs_flua_olange_5605_43_0\"

appears to be running fine, but when I click \"show graphics\" the window becomes unresponsive and requires the app to restart. the other work units are working without any problem.

I just noticed that there is a new version of BOINC (6.4.5) and it is now advertising that these applications can support CUDA now if they so desire to. I for one would love to see Rosetta support CUDA.

Post:
is it safe to abort work units on the older applications in order to focus time on the newer application versions?

I mean, does it affect your results negatively by aborting work units in bulk just to ensure we\'re using the most up-to-date version?
