With regard to CPDN upload server uploadcomlab, Milo says
Uploadcomlab has a new power supply but no new disks, so it's back in service to take some more uploads over the weekend. It will go down again for new disks when the missing part of my order actually turns up (some PCI SATA adapter cards).
Because there are several CPDN upload servers, this uploading problem only affected some CPDN crunchers. If you turned off BOINC network activity because your trickles and zip files couldn't upload, please enable network activity again now.

Milo also says he now expects the SAP server to remain problem-free.

CPDN main project

The HADAM seasonal models now being sent out to CPDN members are a new type. Tolu says
This new experiment supposes that in 1999 we had suddenly found a very, very cheap and fast way of removing all of the anthropogenic greenhouse gases from the atmosphere and that this method was adopted in early 2000. Because the ocean responds slowly, we can suppose that this did not affect the ocean over the 2000-2001 period of Pardeep's simulations. But what affect would it have had on the atmosphere? We are expecting to find that the land would have cooled nicely (away from the coasts anyway), which seems ideal. But we also think that the warm ocean/cool land contrast would have produced more severe storms and rainfall events, which is not so ideal.
These new HADAM models are named hadam3h_c_*. The previous workunits were called hadam3h_n_* and hadam3h_a_*.

The server only sends HADAM models to computers with at least 1.5Gb RAM. However, that isn't enough for computers with Vista, and dual or quad cores also need more.

Reminder: we can select the type of model we want to download next time by editing the ClimatePrediction preferences in our CPDN account.

CPDN main project

As a result of the CPDN's BOINC server version upgrade, on Friday there was no credits export to the stats sites. We hope Saturday's credits export will take place normally.

CPDN main project

CPDN upload server phkup is down. Milo says
That server is down because the filesystem containing the cpdn data was corrupted when the admin upgraded the OS. They are now restoring from backups and say it should be back on-line tomorrow.
This will affect the upload of some computers' trickles and zip files. If you can, suspend BOINC network activity while the problem lasts.

CPDN main project

The phkup upload server is up and running again, but upload server uploadcomlab is down. Milo is backing up its data today so it can have its new disk installed tomorrow. This means that some different CPDN computers are now unable to upload trickles and zip files. If you find that your computer can't upload to CPDN, if possible please suspend BOINC network activity for the time being.

SAP project

The SAP server has been problematic for several days. SAP crunchers have not been able to upload trickles and files. As SAP models are provided for CPDN crunchers from this server, there may also be difficulty in downloading new SAP HADAM models. Milo will investigate this server tomorrow.

(There's never a dull day for Milo......)

CPDN main project

Upload server uploadcomlab is now working.

There was no CPDN credit export to the stats sites on 12 and 13 May, but on 14 May the credit export started again.

SAP project and SAP HADAM models from the CPDN main project

There is a temporary but serious problem with the SAP server. CPDN SAP-HADAM models come from this server. When SAP models contact the server they will produce BOINC manager messages like this or similar:

15/05/2008 10:35:34|CPDN Seasonal Attribution Project|Fetching scheduler list
15/05/2008 10:35:39|CPDN Seasonal Attribution Project|Master file download succeeded

15/05/2008 10:35:50|climateprediction.net|Message from server: Invalid or missing account key. Visit this project's web site to get an account key.

Please do not detach! You have not really got an extra account and you are not really attached twice.
Please do not reset the SAP or CPDN project!
Please do not abort your SAP HADAM models from CPDN or SAP!
CPDN needs your SAP models - only last week a new experiment using these HADAM models was launched!
Please suspend your SAP HADAM models for the time being.
If you are already getting messages like what I've quoted, please if possible suspend BOINC network activity until the problem is solved.
Milo will be doing everything he can to resolve the problem on Friday.

SAP

Milo has fixed the immediate problem of the SAP redirect to CPDN that didn't work as planned and produced the dreadful BOINC manager messages quoted in the above post. If you have messages like that, please ignore them and don't do what they suggest!

The SAP website and forum are now running but the SAP server status page looks as if the SAP server won't accept trickle and zip file uploads at the moment.

The problem of the SAP redirect to CPDN doesn't appear to have been really solved. Thyme Lawn has posted a fix on the SAP forum here.

Thyme Lawn has now modified those instructions. The link to them in the above post is still correct.

SAP

This afternoon Milo managed to get into the Physics department. He has cancelled the SAP server redirect to the CPDN server and upgraded the server software. The SAP server is now completely up and running, though Milo can't guarantee its future reliability.

It should now be possible to run SAP models again and allow them to send trickles and uploads to the server.

Seasonal Attribution Project

Milo's been told that the SAP server will have a new disk and OS installed on Tuesday 22 July, but the server will be down before that for backups to be made. These improvements should allow Milo to make crunched SAP models available to climate researchers worldwide from his new Results website which is still being tested.

SAP HADAM models downloaded from the CPDN main project since May 2008 will not be affected. But CPDN members still running SAP HADAMs created before May 2008 will find that these models cannot trickle or upload zip files while the SAP server is down. If you have one of these older HADAMs you could suspend it from Monday 21 July and process other tasks instead, or suspend BOINC network activity. Check SAP server status here.

BBC Project

The BBC forum has recently been down intermittently along with members' account and model web pages. On a few separate days in July the BBC server has not exported credits to the stats sites. Tolu is looking into the problem.

If this happens again, BBC members who need to post about their models are welcome to register separately on the CPDN independent forum and post there.

BOINC 6.2.14 has been released to the public. Congratulations to Rom, the Berkeley team and all the alpha testers! There are CPDN forum threads with more details and further links here and here. As this is a major new version it's important for CPDN members to read Mike's post and Jorden's FAQ before deciding whether and how to upgrade.

CPDN main project

The daily CPDN credit export to the stats sites did not take place on Friday 1 or Saturday 2 Aug. Milo has now done this manually. On Sunday we should see our missing credits on the stats sites.
