1) Questions and Answers : Windows : Visual Fortran Run-Time Error (Message 35003)
Posted 16 Sep 2008 by old_user519896
Post:
Hello

I have been getting this same kind of message (error 38, kernel32) for a few days. I have successfully crunched one task before, without any message. Nothing has changed on my system, but I did change one thing in the BOINC options: I told it to suspend calculations instead of calculating all the time, although I am not sure the error appeared exactly when I changed this option or if this is a coincidence. I am using XP Home SP3, Avira AntiVir PE and Outpost Firewall on an ASUS laptop. No Messenger, the laptop is just standing idle, and I am not using any screen saver (Boinc or other). When I set the calculation mode to Idle, the message seems to reappear each time calculations resume, but strangely the message box closes itself as soon as I move the mouse pointer. If I change the calculation mode back to continuous, the error appears even more frequently and I have to close it manually. Another strange thing is that Boinc seems to be trickling, as if the error dd not stop calculations.

Update: I rebooted the laptop, restarted Boinc in continuous mode and the error disappeared. I switched back to idle mode and still got no error...

... \"on fast desktops\"! mine is a 2 years old Pentium M. It is my best computer. At that time, dual cores were very new and very hot - physically. The laptop is working 24/7 and it is doing absolutely nothing else, so I don\'t think I can do much better now.

The new task is running very fast, I guess it is a very small one, but the previous task was so long I wasn\'t even sure it would be finished by the limit (around 10 years). I believe the limit does not really exist, so I was not worried about that, but frankly, who can tell if cpdn will still be doing something in 10 years? I wonder if the announced estimated duration was not wrong: I started the task on an even older (5 years) and slower laptop. Although the trickles were more frequent after I switched, the estimated duration stayed about the same.

Thanks for the answer. I\'m a bit unsure of what you meant by \"completion\" since Boinc was telling me before switching to the new task that the old one was going to need a few years to complete. But I am happy because

- you confirmed that what had been accomplished could of use

- the new task has already reached 30% in one week, which means I am pretty sure I will complete it without any problem :-)

Sorry, but I must say you are probably both wrong. Here is the snipped sequence of messages I got one week ago:

I don\'t know if the way the server handles results from \"Compute error\" tasks changed since both of you checked this or if I had another problem, but I know one thing: if ever a task crashes and BOINC loads a new task, I won\'t try to restore, I\'ll let BOINC work on his new one!

One question: is the partially accomplished work of any use to CPDN?

Posted 10 Jul 2008 by old_user519896
Post:
Absolutely. As long as your task continues to return trickles and upload result files the CPDN server will accept them and grant you credits (the page for your task shows a trickle was received last night).


Thanks. I don\'t care about the credits, I am doing it for the results (as we say in French, we are all in the same boat here). I had seen that the server had received the trickle but I was worried the server might not use my results, which would mean I was burning watts for nothing and wasting calculation time.

Thanks for your answer.

Hello

I was happily computing until a few days ago. I forgot that BOINC was running and I shut my computer down. Ouch. I had reached 4% of my task :-(. Next morning I fired up my computer, restarted BOINC, saw him restart computation and forgot about it. But when I checked again a few hours later, I discovered BOINC had decided that my previous task was invalid and had loaded a new one. I felt that losing days of computation was unbearable, so I stopped BOINC, reloaded the last backup and restarted it. What I hadn\'t seen, though, is that the old task/work unit was flagged \"over\"/\"client error\"/\"compute error\" on the server too. Now I have this strange situation: BOINC is trickling but in an invalid task/work unit. Is this any use?

Funny, I just found this out! I was using 7zip (command line version of course) to compress and I saw that 7zip complained that some files were still locked (although in the BOINC GUI the project is suspended). I believe there are some zip switches which could solve the lock issue, but I\'d rather compress when all locks are removed.

So is the procedure Suspend-then-Exit completely ok? Is it any use to do
  boinccmd --project http://climateprediction.net suspend
  boinccmd --quit
  (zip)
  boincmgr

or is --quit enough

... or is there something else required?

Thanks for the idea, JIM. To make things easier, I just created a small batch file which suspends, backups and restarts the project. Now that I know how to do it, I will create another to suspend and backup BOINC before shutting off the computer. I believe I saw tools that allow you to launch tasks before closing Windows.

If I continue at my current rate, my next download should be in about 270 days (plus the unplanned but unavoidable delays). I guess I have time enough to choose an easier job for next time :-D

Thanks for all your answers, everyone. Frankly, when I calculated the number of days which I would need to finish my task, I started thinking about quitting, but the help I am getting here makes me want to stay on board.

I like the graphics explanation better too, but I want to be sure. Now that I know there is a way to backup and recover from a crash, I am going to check if the interface is the culprit as soon as I have a little time.

Here is where I am, now:

- I used a memcheck86 and superpi (32M) without finding anything abnormal (I did not expect to find anything since I had not experienced any crashes on this machine). If my new task crashes too, I\'ll test Prime95, just to be sure.

- Since the hardware did not seem to be the culprit, I attacked the firewall. Here is what I did:

  • delete all BOINC related rules in the Firewall settings.
  • in the BOINC client, ask for a project update in BOINC in order to trigger the Kerio/Sunbelt popup, Kerio asks if access to the internet for this application is allowed.
  • Confirm than you accept all communications
  • Modify the rule for BOINC.exe, accept all communications for BOINC (all zones and all directions) and enable network logging (I\'ll remove logging once I\'m sure it is not a communications issue)



BTW, I made a mistake when I posted the link earlier, this is the correct link

My task has been running for more than 10 hours now, which is a little more than than the 6 hours my longest running time was until now, but of course it is much too early to say if the firewall changes did solve the problem.

mo.v, you made me think of something: I did not install the screen saver, but I did invoke manually the graphical display and play with it. I never experienced any obvious problem with it, but I don\'t know how it works, could it crash the engine but continue to show the rotating earth as if nothing had gone wrong?

Ah, at least I feel we are going somewhere! I like that!
There are a number of common errors which cause many people problems. The first is the Windows Stop message (appears as a Microsoft Send / Don\'t Send dialogue, and -1073741819 in the log)

I believe I have something like it: I found this
- exit code -1073741819 (0xc0000005)

in stderr.out. BUT I don\'t have any dialog. I am using XP SP3, maybe is it related.

Anyhow, this made me understand that my issue could be firewall- or rather kerio-related. I found here some infos about Kerio and I set my rules accordingly. I will check tomorrow if this solves the issue and report here.

Thanks, it\'s much much clearer, now. I hope the aborted tasks are not lost. And I am a bit disappointed by the lack of hints about what is going wrong. I suppose there is nothing you can do about it, but it is frustrating when a software aborts without any information about why it did so. I checked the whole directory tree without finding anything. I found a stderr_um.txt, but it is empty :(

If tomorrow\'s job does not work properly, I\'m going to unsubscribe from climateprediction; consuming watts uselessly is definitely not a way to help climate!

Thanks for your answer.

Your machine is crashing every result you have tried to crunch. The crashes are all the -107 crashes, which are usually hardware related.

Sorry, I don\'t see the crashes as such in the Messages pane. All I see are \"Started download ... / Finished download ... / Starting ... / Starting task ... / Computation for ... finished \" and then the \"Output ... absent\" messages. Nothing I recognize as error messages (except for \"absent\"). Is this as expected?

I noticed you have a mobile CPU, is this a laptop? I also noticed it has a shared memory space for video, are you using the screen saver? Your machine has a light amount of memory for this project.

If you want to continue to do this projected, a few suggestions:
Do not use the BOINC / CPDN screen saver. Recommended use BLANK. Any of the screen savers on that machine are going to take up valuable resources and could cause crashes.

Yes it is a laptop. Sorry, that\'s all I have to offer :-( I don\'t use the BOINC screen saver, though. I used the standard XP screen saver, but I just switched to the empty screen screen saver to see if it improves memory usage.

If a laptop, get it off the \"desk\". If you can use something to raise it a little and allow it to \"breath\" more, or better yet buy a laptop cooler. Make sure all the airflow spots are free of dust.

If you continue to crash models, then your may want to start doing some intensive testing of your machine. Like memtest86+ and Prime95 are a couple good testers.

I don\'t experience any crash. I own two laptops but I currently use this one for BOINC because the other one is having stability issues (probably OS-related) and I use this one to remotely access (TS client) a remote server, so it has more CPU time available. Since I use this laptop to access to my work, I can assure you that any crash would be immediately noticed!

I just noticed your speeds are low for that machine... it is having issues. Make sure you do some of the above cleaning / testing.

I am going to send the other laptop to be fixed. When it comes back, I reinstall the OS and switch to it.

Good luck, and know that not all machines can handle CPDN.

Thanks.

Hello.

I\'m new to BOINC. I registered on 2008-05-28 and I don\'t see anything change on my account (3 days later), my quota is stuck at 1 per day and I see messages like \"Output file hadsm3fub_jotf_005950294_7_2.zip for task hadsm3fub_jotf_005950294_7 absent\". Is everything ok or is there a problem and how can I solve it?
