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.

the \"no finished file\" message is a trivial warning as others have noticed.

On the good side, the new cpdn we\'re beta testing uses a lot less file I/O and I think is a lot less prone to these errors. I was running cpdn and backing up my hard drive to a firewire drive (200GB), doing other stuff, running a virus & spyware scan, and the model was fine (the hard drive light was solid red for two hours).

If you want to reduce them, you could try updating to BOINC v5.8.14 ...

Where do you find this download?

Go to the normal BOINC download page, and click on \'All versions\' underneath the download it automatically recommends for your system.

It changes quite frequently - today\'s version is v5.8.15 - so heed the warning: (MAY BE UNSTABLE - USE ONLY FOR TESTING) and be prepared to swap back, or upgrade again, if problems appear.

And in the special case of CPDN, make sure BOINC is fully shut down and backed up before upgrading.

Hi Beremat. Welcome to the project.

It\'s a Coupled Ocean model, also known as a TCM, Transient Coupled Model.
They\'re all that there is now, and are a combination of experiments 2 and 3 as described here. They can also be described as a hindcast + forecast model.

These models start in December 1920 so as to be fully running by the start of 1921.
They trickle once a year, in early December. The first trickle is at 0.67%

As I recall, the number of users when you first start is 1 because that\'s you, and the total number hasn\'t been found by the program at that stage.
You can see stats on the project\'s front page here.

As for how well your computer is doing, others will show up soon to give you some comparisons. But running the screen saver will slow you down a lot. Those of us serious about the crunching set Windows to use Blank or None under screensaver, and use the Show graphics button in the Tasks tab occasionally.

There are 4 README stickies here with \"things you need to know\".
