I did wonder, but the next has gone through as normal.

Thank you, Sherlock, I didn't examine all that.

Before this new version, work units used to take me 2.5 to 3 hours to process, for which I received credit in the low twenties. The first unit processed using the new version took 7 hours, credit 1.84. Seems rather low.

No, you're not. But no one has yet admitted this is a problem,
so I too will be forced to abort until it is settled.

What about this "refusal to stop" issue ?

1.4 units WILL NOT STOP / wait / suspend.
So my Rosetta RAC is rising, and the others are falling !!!
7) Message boards : Number crunching : there was work but your computer doesn't have enought memory (Message 37418)

DO NOT DISPAIR! I, too, suddenly got this message for the first time, so I tried tweaking my general preferences. I increased the memory available from 50% to 60%, but this produced no change. I increased the swap file setting from 75% to 80%. No change. Did they mean the disc space, I wondered. So I increased this from 50% to 60%. No change.
Then I increased the idle time memory setting from 90% to 95%, and hey presto, down came a fresh unit. But it has the same completion time as the others in my cache. Hmm.

Thanks, that's a start. I will investigate.
I think I did upgrade to Winsock 2, trying to keep up to date, so it may be something else.

After the call for more processing time, I decided to put Rosetta on an old machine which is normally used just for Seti.
Note that the machine operates under Win 95, and consequently will not operate a Boinc Manager later than 4.19.
I keep getting the following error when Rosetta runs:
Unrecoverable error for result HOMOLOG_ABRELAX_hom003_t283__505_888_0
CreateProcess() failed - A device attached to the system is not functioning. (0x1f)
Computation for result HOMOLOG_ABRELAX_hom003_t283__505_888 finished
I have tested LHC, Predictor and Seti, and they run with no problem.
I presume there is nothing I can do to make Rosetta work?

Yes, thanks, all is OK now.
Sorry, Stepan T, to mess up your praise page.

Thanks. I am using MS IE which does not have a Reload button. The only way I could get an up to date view was delete all Temporary Internet Files in Tools > Options. This does not happen with any other website.
Until now, my results were stuck at the day I joined, but I can see some interesting graphs, and the front page news which would have obviated some of my posts.

Sorry to bother you, but why does my Rosetta home page still show user of the day as Morpheus, and has done so since Oct 28 (together with the server status on that day)?
13) Message boards : Number crunching : Have Graphics Arrived? (Message 3566)
Posted 18 Nov 2005 by Martin Johnson
Post:
Yes, I have now used up the old units, and am now able to see the graphics for the new ones. They look GREAT. They give the impression of an electron microscope view of the molecule in all its possible configurations, each config being tested on screen for the search for the one with the lowest energy.
It leaves Protein Predictor looking rather tame.

During my regular daily download this evening, I noticed a 4 MB file "rosetta_graphics_beta...". Although the Graphics button is still greyed out on the wu's previously downloaded, presumably this will burst into life when I come to process the units downloaded today?

Perhaps the answer to this problem is the same as I found on 2 other current threads - on switching projects, LEAVE IN MEMORY! If you don't, and you switch, when you come back, it restarts at some previous point, and re-crunches, again and again, never quite getting there.

Posted 31 Oct 2005 by Martin Johnson
Post:
I am reporting back that "Leaving in Memory" seems to have no detrimental effect on the running of the computer, and it does allow switching more often. I am now set back to my preference of every 20 minutes, and it's nice to see Rosetta carring on where it left off, with no "re-crunching".
Why every 20 mins? Well, it keeps me interested in all the 5 projects on this machine, and stops the "Debts" building up to enormous proportions.

OK, thanks again. I will try leaving it in memory.

Post:
Thank you both for this information. The problem is that there are no readily available guidelines. And Boinc seems to be in its infancy.
For instance, on my faster computer, I have 5 projects running, with roughly equal share percentage. Rosetta units have bottomed out (on Boinc 5.2.2) at a projected duration time of about 30 minutes. Because I cannot ensure that I can connect every day, I set the connect time to every 2 days. So what does Rosetta download today? 51 units! This is a bit silly. I really only wanted 21! Some more tweaking still needs to be done.

Posted 26 Oct 2005 by Martin Johnson
Post:
I believed that the idea of using BOINC was to allow the sharing of resources. If, for instance, I wish to switch between applications every 30 minutes, then I should be allowed to do so.
But not with Rosetta! Some work units are so large that they do not write to disc within the 30 minute share period, and so start again at the previous disc-write. This means the same calculations are done again and again without the percentage increasing, thus wasting much crunch time.
But I have already specified in my preferences that I wish all applications to write to disc every 10 seconds, so that a re-start can be accomplished at virtually any point. All other applications seem to do this.
May I ask if Rosetta will eventually allow this?
