If you are running boinc_gui, which is the one were a boinc icon appears near to the clock on the taskbar then you can copy a boinc_gui shortcut into your startup directory of the start menu.

If you had done a default install of boinc then this would already be there, depending on what user profile you installed boinc under.

I believe your talking microsoft windows os.

I’ve got some WUs that BOINC downloaded after a fatal crash, but I restored BOINC to a previous state. I copied the BOINC directory before restoring, therefore can I copy the new WUs into the working directory …/projects/climate prediction.net ? Do I need to update any *.xml in the main BOINC directory for it to recognise these WUs and starts them when the present models are completed ?

BTW BOINC did not do much work on these new WUs hence the CP server thinks they are in progress and new, see <a href="http://climateapps2.oucs.ox.ac.uk/cpdnboinc/results.php?hostid=93819">results</a>.

These restored WUs are sending trickles to the CP server with no problems, see <a href="http://climateapps2.oucs.ox.ac.uk/cpdnboinc/show_host_detail.php?hostid=93819">computer summary</a>. My only concern is the CP server believes these restored WUs are over with the outcome of client error; so when it completes the model will the CP server accept it ?

If you are running boinc_gui then that will stop when you log off. Running boinc_cli as service will ensure that it runs all the time, unless PC is turned off!

To run the boinc_cli (command line interface) first stop boinc_gui (graphical user interface). Then delete the boinc_gui shortcut in the "startup" directory of your start menu, thus disabling the automatic start of boinc_gui.

To start boinc_cli goto start menu --&gt; run and type: "cmd"

In the cmd window type: "cd c:\program files\boinc"

This is the default location of the installed boinc program. You may need to adjust this to the appropriate location.

To install boinc as a windows service type: "boinc_cli -install"

To start boinc type: "net start boinc"
To stop boinc type: "net stop boinc"

Now exit cmd window and right click "My Computer" on desktop and click "Manage".

In the "Computer Management Console" goto "Services" and look for "BOINC". Double click to open and set startup type to "Automatic".

Restart the computer and you'll notice the service is running automatically in the background all the time.

Other boinc_cli arguments are:

-attach_project
Attach this computer to a new project. You must have an account with that project. You will be asked for the project URL and the account ID.

-show_projects
Print a list of projects to which this computer is attached.

-detach_project
URL Detach this computer from a project.

-reset_project
URL Clear pending work for a project. Use this if there is a problem that is preventing your computer from working.

-update_prefs
URL Contact a project's server to obtain new preferences. This will also report completed results and get new work if needed.

-return_results_immediately
Contact scheduler as soon as any result done.

-run_cpu_benchmarks
Run CPU benchmarks. Do this if you have modified your computer's hardware.

-check_all_logins
If 'run if user active' preference is off, check for input activity on all current logins; default is to check only local mouse/keyboard.

-exit_when_idle
Get, process and report work, then exit.

-allow_remote_gui_rpc
Allow GUI RPCs from remote hosts.

-help
Show client options.

-version
Show client version.

You could have leaky memory. Under task manager/processes enable the non-paged pool and see if one of the processes is eating up NP memory with respect to time.

This is a stab in the dark, but here goes. As you've tried this with two different models I don't think it is model related. That leaves the hardware. What changes slowly as the model runs? Massive amount of data generated, hence is your laptop filling up either in physical RAM, virtual memory or hard disk.

Just a thought.

27) Message boards : Number crunching : backup and restore WU (models) (Message 7444)

I have now setup scheduled tasks to daily backup the boinc program file via the XCOPY command. First, it stops boinc_cli by “net stop boinc” then waits 1 minute before it copies the boinc program file before waiting another minute to start boinc_cli via the “net start boinc” command.

When I want to recover boinc to a previous state with the backup do I replace the complete boinc program file with the backup or do I replace just the projects/climateprediction.net directory within boinc program file?

Thank you for useful tips on overheating PCs.

I would like to check that a client error with exit status –5 (0xfffffffb) does mean that the model fatally stopped due to a computation error by the computer and NOT the model.

I believe I've got stable PCs as I've built both of them myself with overclocking in mind. Now, I’m not o/c the PCs for boinc due to possible unstable response. Both PCs are Pentium 2.60 GHz with HT enabled on Abit and Asus motherboards with good cooling. The Abit based PC has been running boinc continuously for nearly a week now with no problems. Whereas the Asus based PC has been having problems with client errors and fatally stopping models.

I don’t think the fatal CP model errors are due to hardware whether overheating or not. I say this because the errors are not appearing to be random or when I’ve left the PC unattended for long hours. Instead the model errors occur when I’m using the PC.

I should highlight that I’m running boinc_cli as a service and I don’t use the boinc_gui or the screensaver. Therefore it should not be related to graphics drivers or card error.

In task manager it is shown as two hadsm3um_4.04 processes taking 50% CPU usage each, plus two other hadsm3_4.04 processes appearing to do nothing. When an error occurs only the hadsm3um_4.04 in slot 1 of the cpu dies.

Could I recover from this error by restoring a backup of the boinc program file directory?

I’ve be participating in distributed computing for several years running seti@home and then United Devices grid application clocking up over four years of CPU time. I thought I would try the climate prediction modelling, only that it does have one critical drawback compared to the other DC applications, WU size and time to process.

The WU size and time to process is not an issue for me.

Take the WU size requiring I believe 700 MB to 1 GB, which considering how cheap hard drives are at less than £30 for 40 GB should not be a problem for any high spec PC.

The time to process, which in my case on a P4 2.60 GHz HT takes 10 hours per trickle, is not a problem as the PC is continuously on and running boinc_cli as service with the CP models going 24/7 100% processor usage. The time to process only becomes a problem when the model crashes and reports a client error to climateprediction.net and starts a new model. To the user (like me this week) this feels very frustrating as those CPU cycles appear to have been wasted. My solution for this would be for boinc to automatically backup the vital data files created and then recover when it fatally crashes. This would require extra HD space but it would easily fit in the default 10 GB required. If users can only donate 1 GB HD, then the recover option due to fatal boinc crash is disabled.

It must be expected then boinc will have a fatal crash on some computers. But if it was able to automatically recover the user would not get so irritated and wander if it is worth running CP models. Compare this to over DC projects where a WU only takes a day to complete, in these cases if it fatal crashes it does not feel so frustrating.

I must add that the major plus for the CP project over other DC projects, is the unique model given to each computer to process. That makes it feel more personal and the fact that each model when completed is adding to the vast pool of CP data to then be sifted by some low-paid PhD student! Moreover, you can actual see the post processing progress of the project as a whole, unlike UD grid where the post processing of the protein folding for cancer, anthax, smallpox and human genome is secret due to commercial impacts etc.

30) Questions and Answers : Windows : hadsm3um_4.04 and hadsm3_4.04 (Message 7420)

Post:
On my Intel P4 HT PCs I’ve got boinc running with two model programs named hadsm3um_4.04 due to the dual nature of the hyper threading CPUs. But I also have two other processes named hadsm3_4.04 which appear to be idle in the task manager. What is hadsm3_4.04 and why have this process running with hadsm3um_4.04?

I’ve been running cp boinc for a week, with some frustrating lost models. How can I backup and then restore from these backups under WinXP OS?

I was thinking of running a daily scheduled task of a batch file that XCOPY to another PC on the network. I use this method for daily backing up vital data on my PC to a remote PC, encase of theft, fire etc. This method works fine, even if I’m accessing and using the files that are being copied.

I’ve got boinc_cli running as a service all the time. Can I apply this automated method to backing up the boinc directory whilst boinc_cli service is running? Would conflicts occur if both boinc_cli and XCOPY were accessing the same files at the same time? The likelihood of both boinc_cli and XCOPY accessing the file at the same time is high as I believe boinc writes to the directory every 144 timesteps, which on my PCs is every 8 to 9 minutes.

The next question is how do I restore from these backups? Do I stop the boinc_cli service (net stop boinc) and then completely replace the boinc program file directory with the backup. Or do I just replace the project\climateprediction.net directory in boinc program file?

Ian

PS.
By the way if you’re interested in the copy batch file it is:

ECHO/ &gt;&gt; CopyFile_Vesuvius.log 2&gt;&amp;1
ECHO/ | DATE | FIND /V "new" &gt;&gt; CopyFile_Vesuvius.log 2&gt;&amp;1
ECHO/ | TIME | FIND /V "new" &gt;&gt; CopyFile_Vesuvius.log 2&gt;&amp;1

XCOPY "C:\PhD" "\\Hotchpotch\Backup_data\PhD" /D /E /V /C /I /F /H /R /K /Y /Z &gt;&gt; CopyFile_Vesuvius.log 2&gt;&amp;1

ECHO/ | TIME | FIND /V "new" &gt;&gt; CopyFile_Vesuvius.log 2&gt;&amp;1

This batch file when run as a scheduled task automatically backups my data and generates a log file that is date and time stamped. The XCOPY commands can be found at: http://www.computerhope.com/xcopyhlp.htm
