1) Message boards : Number crunching : Linux/Mac/Windows segmentation (Message 51881)
Posted 128 days ago by Profile Conan
I have a couple of Fedora 16 64 bit systems. To start my BOINC sessions I would click on the "Files" icon to launch the files system, navigate to the BOINC folder and then start BOINC.
I would leave the "Files" open so I could easily go back to check things in BOINC or the Download folder or other files searches.

I found after doing this for a long time without a computer reboot (such as long running projects that restart from scratch if you start BOINC again), that my systems start to slow down and I start having memory issues.

The "Files" programme starts to use a lot of resources over time.

By closing it down when I am not using it (after I have done my file searches, started BOINC or installed some download), I found that the whole system came back to life and I got my memory back (the computers memory, not mine as that is already lost).

So an innocent programme could be causing you an issue.

Thanks to all who helped in getting this done.

Les,

Yes, thanks, I know this, I was responding to a couple of lower down replies as to me the issue did not seem clear.

I am still processing them even with the much lower credits, as I am hoping the science or results, may come to something useful.

Thanks to the moderators for their response in this matter.

4) Message boards : Number crunching : what is this stupid message (Message 51764)

I'm set to get new work, but communication keeps getting deferred for one hour. In the meantime, Einstein and Seti continue working just fine.


The only work for Linux at the moment (as of today 5th April) is

hadam3prm3pm2t_eu (hadam3p global model with hadrm3p regional model with MOSES II land scheme and TRIFFID available) (currently no graphics) (Linux only)
Tasks ready to send 13,462

If you have your setting set to receive all model types you should pick some of these ones up.

As I noted in an earlier message

[Quote]I noticed that the credit awarded is exactly the same as the other (non-MOSES) Europe work unit type, so perhaps they have just got it mixed up.

They seem to have used the same crediting system for each Europe model even though they are completely different models.

This model is still not getting the correct credits, less than a 3rd of what they should be getting.

I don't have any A10 or similar CPUs but I have the older Phenom II type CPUs and to give you an idea of their run times on a couple of different models here they are (they run at 3.2 GHz standard clock, running Linux Fedora 16 64 bit)

This is quoted RUN Time, CPU Time is often quite a bit less,

MOSES II Landsurface Scheme around 1,008,800 seconds (280 Hours)

MOSES II and TRIFFID Europe around 1,004,000 seconds (279 Hours)

Coupled Model Full Resolution Ocean from 1,230,000 to 1,550,000 seconds (341 to 430 Hours)

I currently have 2 MOSES II and TRIFFID models running and they are

192 Hours at 67% with 92 Hours to go
242 Hours at 83% with 47 Hours to go

This at least will give you an idea as to what to expect, I am hoping that as you have much more recent chips then the times will be a lot lower, I am hoping this as I will have to update soon myself.

8) Questions and Answers : Windows : CPDN gone from Project tab after crash (Message 51646)
Posted 166 days ago by Profile Conan
Rather than re-attach to the project, which might cause multiple host instances, just try stopping BOINC, closing it then restarting it. You should not need to reboot but as it may be a driver issue then perhaps a reboot will sort everything out.

Does anyone know if this credit error was corrected?

I am not keen to run this WU I have just downloaded for 1,000,000 seconds only to find I am getting a 5th of the credit I should be getting for this WU type.

10) Questions and Answers : Unix/Linux : Multiple CP task management (Message 51410)
Posted 197 days ago by Profile Conan
Are you sure that your preferences are set to use 100% of CPU and to use all 2 cores available?

If it is not on 100% then BOINC sees the 1000 hour work unit as more important and throws most resources at that problem.
