Message 52980 - Posted: 29 Nov 2015, 22:48:00 UTC

OK, getting replies back, so several things:

The following is mostly intended for the mods, but I've included it all:
As the number of failures appeared to steadily be increasing for batch 238 (wah2_ri version 7.08) I have now removed the remaining workunits from this batch from the queue. However I am still very interested in how the workunits that have already been taken up progress. If you have any of these workunits running on your machines and are able to capture the working directories or .out files this would be very useful to us. Also if you have other information on the failures - when they are failing / how long they ran for this would also be helpful. Similarly if you have information on these workunits running successfully that would also be of benefit.


Part of a separate email:
This is the latest version of the newest incarnation of the W@H application, the region independent, start date independent, length independent with latest land cover model


This latest batch are submission for the MARiUS project. details of which are on the site.

Just for those that have not done this before, (like me).

I have two of these, one of which has just started running, It has failed on a previous machine.

Where and when are the files present, and where would you like them sent, I am assuming this is only for files that fail.

Thank you.

Kevin

Information about speed of progress and size of zip files when created may also be of interest.

Currently running four on my i5 machine. One repeat (computing error after 32secs!) and three new ones. Up to about 7% after 12hours.

Kevin, the files are in ..../BOINC/projects/climateprediction.net and the main files of interest are those ending iwth _x.zip where x is an integer between 1 and 13. If things work normally these will get transferred to the relevant server automatically but I am currently at 58% through transferring about 1GB worth of files through to Andy for the beta site which is still down.

I have 6 of these tasks running on my i7 Computer.
Estimated time for the tasks was 122 hours but 9% has taken 19 hours for the first task, so they will probably take just over 200 hours.
First trickle at about 9%,

I have 2 more tasks at 8.4%, so they should send a first trickle soon.

These units have sent two trickles each so far. Taking about 4.8s/ts (i5, 3.5GHz).

How often do these tasks checkpoint? Looking at the task running now, it seems it's been over 50 minutes of CPU time since the last checkpoint.

All CPDN models checkpoint at fixed points in the calculation. For these models it's at the end of each model day, with trickles and uploads being made every 30 model days.

My 15 has a checkpoint interval of just under 50 minutes and for the Q6600 it's around 70 minutes.

Two of my WAH2 models from the 29 November batch have completed. Some others have failed early on: at least one of those has made some progress on another computer, which makes we wonder whether they don't like being run with too many in parallel (my habit is to run 25% CPUs, except when getting new work when I put CPUs back to 100% - the crashes all occurred during the 100% period).

Message 53038 - Posted: 6 Dec 2015, 16:53:33 UTC - in response to Message 53037.  

I'm running at 75% CPUs (6 tasks)during the day and 100% CPUs (8 Tasks)during the night on my Win 10 64bit i7.

One WAH2 failed having trickled once.
Another WAH2 failed after 8 trickles.
Both failed during the day, so not at 100% CPus.

The other WAH2s are at 70% completion.

Oops. Wrong models.
I'll move this to the CM3n thread.

The memory load for WAH2 seems to be much higher than was the case for previous applications. My wah2_eu25 tasks have a total working set size of around 460MB and I've changed the project resource shares on my Q6600 (which only has 2GB of RAM) to prevent it from running more than one of these tasks.
