    We\'ve fixed the file input error on Macs for the MAPRELAX jobs. Also, we\'re trying a new feature (COMPTOSERVERS) where at the end of a simulation, Rosetta compares its fold to the predictions made by a dozen other algorithms. (Those predictions are sent to the clients in a compressed format.)

    Let us know if you see any bugs. Also, please let us know if the memory requirements for the MAPRELAX jobs are unusually high.

      Some of the MAPRELAX units on my machine are erroring out after 15-20 minutes (normal runtime for me is a little over an hour). stderr out reads:

      <core_client_version>5.4.9</core_client_version>
      <message>
      Incorrect function. (0x1) - exit code 1 (0x1)
      </message>
      <stderr_txt>
      # random seed: 3057981
      ERROR:: Unable to obtain sequence information.
      fasta file must be provided.
      ERROR:: Exit at: .\\initialize.cc line:236

      </stderr_txt>


      Looks ok up till that point. Graphics are good, at least. Upon hitting the error point, the graphics window just disappears.

      A successful MAPRELAX
      Error result

      I\'m on Windows XP SP2, dual Pentium 4 processors.

        Got one finished in ~ 45 min, memory usage unknown (finished sooner than I was able to check)

        Another one finished after 55 min, 230MB usage

        Dumb question: apart from lower traffic of higher \"Target CPU run time\" - does having it set to let\'s say 12 hours brings \"better\" (i.e. more precise) results?

            Hi,

            I had big problems with the last rosetta-versions, so I had to stop crunching for RALPH.

            Now I tested 5.16 on that machine, where I got the problems; the WU took 3 1/2 hours, the problem didn\'t appear until now.

            But, memory-usage has grown up; the actual WU was at 318 MB Main-memory, 339 MB virtuel-memory :-(

            BOINC is running as a service, so no rosetta-screensaver ...

            The only thing could be, the box uses a normal windows-screensaver: WindowsServer2003 (That is the name of the screensaver !)


            ____________


            Supporting BOINC, a great concept !

              In a word, No. At least not yet. It simply makes more models. Rosetta is not like a lot of other projects where a particular refined result is sought by a particular machine within a specific work unit. However, the project is starting to experiment with approaches that do sort of \"Learn\" as they go, and refine the work based on each model produced.

              The goal here is to provide each work unit with a different starting point, and have each system adjust the work looking for the lowest energy level it can find among the models it can create in the time allotted. So the more models made the better. However, ultimately all of the systems are actually searching for the same result. If we ever get to the point where the project can send out 10,000 work units and they all come back with the same result, and it correctly reflects the actual shape of the protein, then we will have reached part of the goal. If we ever get to the point where a single system can reliable predict a protein shape given the amino acid sequence, we are done.

              Since what is being sought is a reliable way to predict the protein shape, at this point the more models returned the better. The hope is that among those returned will be the correct one. If that happens then it is presumed that the technique that was used could repeat the performance.

                Sofar, BOTH ralph 5.16 WUs errored out MAPRELAX_TEST_hom015_1fna__516_1_1, MAPRELAX_TEST_hom025_1fna__516_19_0

                with \"Incorrect function (0x1) - exit code 1 (0x1)\"

                This is on a very stable PC, which runs Rosetta flawlessly for the past 4 months (apart from 2-3 WUs which were bad).

                  Adjust u preferences to \"remove from memory\" when swapping projects,
                  to free swap space !

                  Now,
                  that enough checkpoints are done, this should be OK, for both ralph & rosetta

                  I had sucessfull run 5.16 on a Linux pc with 256 MB ram.
                  limited to use 35% of swap at maximum, to not crash the OS
                  (user of this pc is a heavy user of edonkey)
                  and its swap space is small ... less than 1MB

                          While is see many reports of the memory issue, I have not seen this on my machines. Both the Windows and Mac machines look normal and even approximate the memory foot print for einstein. In any case the application always moves out of the way if I use the machines for any other tasks.

                            Running a 5.16 wu now for all of 30 minutes (XP Pro SP2, P4, 1 GB mem), and memory usage is already high: 174K memory, 191K VM. These numbers aren\'t intolerable but they\'re higher than I\'m used to seeing from rosetta, and make me think it will climb into the range I reported on earlier. I\'ll be away most of the day,;will report back when the wu has more mileage.

                            See also this post on the number-crunching thread; it reports 690MB which is higher than I\'ve seen.

                            p.s. I leave boinc apps in memory when switched. Are these high numbers only happening to machines which leave rosetta in memory when preempted?

                              Update before I hit the road: 1 hr 31 minutes into the wu, memory now is 325MB peak 329, Vm size is 341MB. PF ranging from 0-1K/second. Avail memory down to 74K, will see if the box is still functioning when I get home!

                                  Ralph 5.16 WU\'s running fine so far, but, they consume a HUGE amount of RAM. The two WU\'s that I have running right now on my dual-core Athlon 64 X2 3800+ are using 664MB and 317MB of RAM respectively. VM usage is slighly higher than that for both.

                                    I had a few of these as well. I feel certain they are bad Work Units.

                                    I noticed a string of 5 of these missing Fasta file errors on my list, as well. Are some of the WUs taking advantage of features in Boinc 5.4.x that aren\'t in the Boinc 5.2.13 client?

                                            The MAPRELAX wu I reported earlier is now just shy of halfway through its 4-hour task. 149MB in memory, peak of 405MB, VM size 416MB. Not as bad as some, but more than I\'m comfortable with. I\'m going to suspend some other projects and restart boinc to lessen the competition until this wu finishes.

                                            If this large memory usage is in fact due to the type of wu and not leakage or some other bug, it would be nice if we could set willingness to crunch memory-gobbling tasks in host preferences.

                                            Of course there are no host preferences, but even a project-wide preference setting would be helpful for many of us.

                                              Just missed the edit-post deadline... I waited for a checkpoint then restarted boinc. At the time of the restart it was just beginning model 8. ralph was consuming 217MB memory peak 405, VM size 468MB.

                                              On the restart, it went up to about 93 MB peak 95, VM 117 MB. It\'s growing though; as I type this it\'s at 130MB memory peak 13, VM 145MB.

                                                  Let it run. It is a test Work Unit for CASP7. It is probably just a large Work Unit. Do not be surprised if it suddenly jumps to 100% at the end of the first model. Do not stop Boinc Or Rosetta or it will start over at 0%.

                                                  If it gets to the place where is has run longer that about 5 times the setting for \"Time\" in your preferences, it will either be stopped by the \"Watchdog\" or you might want to consider aborting it manually at that time.

                                                  Keep us posted.

                                                    Hi sTrey: This is a really good idea -- allowing users to set a preference for \"big jobs\". Its an idea that has come up a few times on the message boards, and we\'ve contacted the BOINC team about it. For now, we\'re sending these jobs to machines with larger memories -- and we\'re tracking down ways to reduce the memory requirement.

                                                    The MAPRELAX wu I reported earlier is now just shy of halfway through its 4-hour task. 149MB in memory, peak of 405MB, VM size 416MB. Not as bad as some, but more than I\'m comfortable with. I\'m going to suspend some other projects and restart boinc to lessen the competition until this wu finishes.

                                                    If this large memory usage is in fact due to the type of wu and not leakage or some other bug, it would be nice if we could set willingness to crunch memory-gobbling tasks in host preferences.

                                                    Of course there are no host preferences, but even a project-wide preference setting would be helpful for many of us.

                                                        An update for those of you who noticed the unusual growing memory of ralph with MAPRELAX jobs. I\'ve partly pinpointed the problem to something that was introduced in the last month in the BOINC windows API. It only causes a growing memory footprint on windows (not linux, that\'s why I didn\'t see it originally) and only on those particular jobs. I\'m contacting the BOINC team about it -- hopefully this will be fixed by the next ralph. It may also be a useful lead into reducing memory requirements for Windows machines. Thanks to sTrey and others for bringing this to our attention!

                                                        The MAPRELAX wu I reported earlier is now just shy of halfway through its 4-hour task. 149MB in memory, peak of 405MB, VM size 416MB. Not as bad as some, but more than I\'m comfortable with. I\'m going to suspend some other projects and restart boinc to lessen the competition until this wu finishes.


                                                        Just missed the edit-post deadline... I waited for a checkpoint then restarted boinc. At the time of the restart it was just beginning model 8. ralph was consuming 217MB memory peak 405, VM size 468MB.

                                                        On the restart, it went up to about 93 MB peak 95, VM 117 MB. It\'s growing though; as I type this it\'s at 130MB memory peak 13, VM 145MB.

                                                                      In part yes, and with the help of the people running RALPH they will eliminate it.

Suddenly my computer crashed...i initially presumed it was nothing to do with the workunit. After a quick reboot i started BOINC back up again and started the work unit again from scratch due to its lack of making a checkpoint. It again seemed to be running fine but after about 55 minutes my computer crashed again. After another reboot and starting BOINC up again the work unit froze after 8 seconds...i had to end the process in task manager so the work unit gave me the computing error...

                                                                                          If you require any more info please let me know...

                                                                                              back to topic :)

                                                                                              got no stuff in the searching and accepted boxes just like wizzszz in his screenshot, i was able to get the structure in the low energy screen though through moving it randomly around, it was somewhere offscreen, looking ok at first, but started to get randomly broken after a while. now at 1.561% (or a little earlier maybe) everything looks like its normal, all pics where they should be, and the structure in the low energy window is in the center now too when i move it around.

                                                                                              doc :)

                                                                                                nothing in accepted and searching, randomly broken stuff in low energy. at 1.561% all pictures look normal and the accepted energy graph looks like its starting from the beginning like if it was a new model while its actually still on model 1.

                                                                                                    just got this WU
                                                                                                    got no stuff in the searching and accepted boxes just like wizzszz in his screenshot, i was able to get the structure in the low energy screen though through moving it randomly around, it was somewhere offscreen, looking ok at first, but started to get randomly broken after a while. now at 1.561% (or a little earlier maybe) everything looks like its normal, all pics where they should be, and the structure in the low energy window is in the center now too when i move it around.


                                                                                                    I managed to nab a few WUs, though I\'m currently running with a lower 1 hour setting on account of having a fair amount of Rosseta WUs to turn in, though if need be, I can play with the time setting there.

                                                                                                    Anyhow, I\'m seeing this exact same problem on my computer. It\'s a t283_lowHB_LOOPRELAX_hand_aligned_hom... WU type

                                                                                                    Edit: Model number 2 didn\'t show anything in those 2 windows as mentioned above. Model 3 is showing a little something in the upper right hand corner of the windows for those 2, which has now turned to look like the low energy window... Model 6 is also messed up like model 2. Whatever this is, it might be specific to some models within the same WU, though not others...
