Hi,

I have around 164Mb of "old" data relating to a previous CPDN WU that I was working on and which subsequently crashed with a Fortran error. BOINC then downloaded a new CPDN WU for me to crunch.

So, can I safely delete these "old" files? Is anyone likely to need them. If so, then I'll WinZIP them up and email them to whoever wants them...!

regards,

Timbo

The CP team are planning to look at the failed runs sometime but it could be a long wait. In the meantime I don't think they can cope with the data storage nor with the manual effort of taking attachements off emails and placing them in a database. I'd be more inclined to keep it, if you were well into phase 2 or 3. I wouldn't worry too much if it was lost, so no need to keep backing it up. So if you have lots of free disk space and can place it in a folder where it doesn't cause your backups to take longer that may be worth doing.

Hi "crandles"

Thanks for the reply.

Following on: Can CPDN "use" any of the data that BOINC submitted BEFORE the Fortran error (which occurred before the WU actually finished)

I cannot remember exactly how far I got through the WU, so it's really a question of how many other failed CPDN WU's are there?
(If "many" then they are unlikely to miss one WU I've deleted that was unfinished - if only a "few" then at some point they'll want the unfinished data back somehow? And who can be bothered to email a 164Mb ZIP file?)

There is a lot of failed runs out there. There is talk of only 1 in 8 runs being fully 45 years completed improving to about 1 in 7. However over 70% of model years are in fully completed runs so you can tell there are an aweful lot with little if any time.

If your 164MB is not compressed that sounds like about 10 years into phase 1. Though I am not sure and it could be early in phase 2. If that is compressed then it will be phase 2. If everyone is told you may as well just delete them because there are lots around, then maybe there will be a shortage. I cannot image there will be much use if you haven't finished phase 1 but I could easily be wrong about that. BTW The fifth character of most phase 1 files is an 'a' whereas for phase 2 it is a 'b' and 'c' for phase3. There are typically 15 numbered files one for each year for each name.

Hi "crandles"

Thanks for the further help,

I've got 42 files from this old WU.

I've actually got 7 blocks of 6 similarly named files, namely:
30uyaa.pa11c10 -> 30uyaa.pa16c10
30uyaa.pc11c10 -> 30uyaa.pc16c10
30uyaa.pd11c10 -> 30uyaa.pd16c10
30uyaa.pe11c10 -> 30uyaa.pe16c10
30uyaa.pf11c10 -> 30uyaa.pf16c10
30uyaa.pg11c10 -> 30uyaa.pg16c10
30uyaa.ph11c10 -> 30uyaa.ph16c10

(totalling 132Mb)

So, I guess, I didn't get that far into phase 1 and so I'd hope that this WU would be resent to some-one else (eventually), as the WU never got finished.

You can tell exactly how far you got into the model run by:
- going into "Your Account" on line,
- selecting "View Computers",
- select "Host" from computer in question,
- click on the number of "Results",
- and then in the list select the appropraite "Result ID" (can take a little searching to find the right one)
- then selecting the "Trickle #"

When viewing the Result IDs I find myself selecting each one in the list till I find the numbers similar to what you have quoted. Also, you can look at the same time to see if the particular model has been sent out again and if someone else had any luck completing it.

Hope this helps a bit.

Hi DaveN,

Thanx for the info - I've actually done a little bit of "digging" and have noticed that many older WU's are likely to be sent out up to 5 times, depending on whether previous hosts have actually replied with any trickles of data.

In my case, my previous WU has actually been completed by another member (and with 2 other hosts "in progress"), so I would guess that they are unlikely to need my old data.

So, I'm gonna recoup around 160Mb of HDD space.

(FYI - I only sent 8 trickles on this old WU, so I doubt any real loss would occur if the data is deleted at my end).

rgds,

Timbo
