I have just installed BOINC and and trying to run the CPDN application. I have a cable modem and normally get 1-2 MB downloads. Downloads from this server are so slow that I haven\'t completed one in over 18 hours of trying. The speeds indicate 0.18 KB and none have completed. NO WORK is being done while the client waits for data!

I have searched this site (itself very slow) and cannot find a place to report this problem.

Welcome to CPDN. If this is your computer: 941086 it looks like it has downloaded two tasks yesterday, about 2pm UTC 8288832 and 8288814. These should be visible in the tasks tab of Boinc Manager. There are a lots of useful hints and tips on running the models in the boards eg here README posts.
If the client doesn\'t seem to be running, can you copy and post the messages from the BM messages tab,and I\'m sure others will try to help you.

I have started two downloads, but they are still running, elapsed time 3-4 hours for each of those two tasks. My log is showing:

I have had no problems with big file uploads and downloads over the past 24 hours.
(4 new hadam models; started download at 2.06pm (Sydney time), and finished at 2.16pm. Admittedly, I did have all of the auxiliary files from previously. :) )

It\'s possible that the problem may be with your ISP. If this is AOL, then note that they have had file size limits in the past, and this may still be the case.
It may also have something to do with a proxy server, if your computer is with an an educational or business place.

Hi Neil, welcome to the forum.

When the CPDN server backs off the download for increasingly long periods, in future you can make it try again almost immediately. In the Projects tab of BOINC Manager you can highlight ClimatePrediction and click the Update button.

If you need to check whether the CPDN server is really down, in the Taking part in CPDN section of the menu on the left of all the forum and website pages you\'ll find the Server Status page.

The trickles after every .625 of each model year are very small so you shouldn\'t have a problem with them.

At the end of each 15-year phase of your HADSM models they will do some post-processing and generate a file for upload. Could I suggest that in the READMEs recommended by Hagar you select a backup method (Les\'s manual method works excellently). Ideally you should back up the BOINC Data folder regularly, but at the least I think you should back it up shortly before these files are created (ie before the end of November at the end of each 15-year phase). By doing that, if your file upload fails you can restore the backup and make the model generate it again. It would be maddening to process 15 years of data then lose the file during upload.

You\'ll see these files when they\'ve been created in the Transfer tab of BOINC Manager.

Congratulations on your persistence!

I think most members would report this sort of problem in Getting Started or Number Crunching, but cafes are always good places for discussion of everything. I suggest that if you have further similar problems you should post in this same thread; you wouldn\'t need to explain the situation again.

It\'s possible that you\'re having problems with a recent version of HTTP somewhere.

Look in your BOINC data folder, and see if you have a cc_config.xml file.

If so, add the following under options:
<http_1_0>1</http_1_0>

If you don\'t have the file, create one with the following:

<cc_config>
<options>
<http_1_0>1</http_1_0>
</options>
</cc_config>


You can use Notepad, but make sure that you use: All files in: Save as file type

This option will force the transfers to use the older HTTP protocol.
