Checkpoint saving and other info needed
So, my C2D is running 2 CEP jobs concurrent and have set the checkpoint write to disk interval limit from my usual 999 seconds to 60 seconds, booted the device and get the below showing incrementally increasing time-spans between writes, which makes it of interest to know when the last one was if considering to shut down a device without loosing too much progress.

Going through the the list found a strange double within a second, in bold.

So, is anybody seeing this too and what times do they take?

Also, has anybody seen the download file size by coincidence in the BOINC manager transfers window? Like to hear as to update the project matrix with some good "spread" info.

thx

Hi Sek,

Probably you missed it, but I already posted this on the beta test forum:

http://www.worldcommunitygrid.org/forums/wcg/...2475&offset=80#193823

Those 2 extra checkpoints were also within 1 second.

Hopefully I could help you this time smile

Re: Checkpoint saving and other info needed
okay thanks, something to add to the checkpoint saving FAQ.

Download info: Took cruncher off line, increased cache by 0.5 days, went on line and saw a 7 part task download. Took the machine off line again and found the 7 totaling 531kb.

The result file sizes are quite variable. Had almost 11mb on one of the Beta's.

Taking UL/DL, 11.5mb for 22 hours is much better than SIMAP can offer, by a long way ;D

Not seen in BoincManager's transfer window (unlikely to catch them and I won't try) but from my projects folder, out of the three WUs that are waiting to start two total 531 kB and one 411 kB for their seven files each. All three are type-A WUs.

Cheers. Jean.

Re: Checkpoint saving and other info needed
Hello Sek,

Another thing I noticed, is that checkpoints are written at least at exactly 10%, 20%, 30% etc. of runtime.

Edit: And also with 5%, 15%, 25% etc.

So CEP seems to save checkpoints every 5% of runtime at least.

Cheers

Re: Checkpoint saving and other info needed
So CEP seems to save checkpoints every 5% of runtime at least

In fact CEP WUs save checkpoints every 2.5 % of runtime, at least for the current type-A WUs.
Which is not that much when you get one of those monster WUs which may last more than one day on a Q6600 or more than three days on a P4!

Cheers. Jean.

Re: Checkpoint saving and other info needed
Regarding the size of the result files to upload it seems that there are no longer those big files that we have seen at the beginning. During the beta test and with the first CEP batches I used to count a total of 0.5 MB per hour of Q6600. But for the monster WUs I have returned today (from batches '17 and '18) they were about 1 MB.

To be confirmed, if possible.

Cheers. Jean.
