1) Message boards : Number crunching : You are using the wrong URL for this project (Message 22962)

Post:
If newer Boinc Clients only accept climateprediction.net as a valid URL, you should update the Dokumentation. E.g. on http://climateapps2.oucs.ox.ac.uk/cpdnboinc/download_main.php it says:
You will be asked to enter the project\'s URL, which is www.climateprediction.net. The BOINC client should then connect to our server.

The 124 hours is approximately the CPU-time used by CPDN before the last restart of the Boinc client.
3) Questions and Answers : Unix/Linux : CPDN writing to stdout (Message 12119)
Posted 27 Apr 2005 by old_user21969
Post:
A message is logged after every timestep like this

29lj_300126824 - PH 1 TS 100904 - 03/10/1816 04:00 - H:M:S=0131:25:09 AVG= 4.69 DLT=34.44

I run boinc with the "-redirectio" option so the timestep messages are written to the file stdoutdae.txt. When that file reaches a certain size, boinc moves the content to stdoutdae.old and writes new messages to the beginning of stdoutdae.txt. But the CPDN Client continues to write at the old end position of that file. This results in a huge file stdoutdae.txt which has a big gap between the the first boinc message and the first timestep log.

Example:
2005-04-27 16:00:03 [climateprediction.net] Sending request to scheduler: http://climateapps2.oucs.ox.ac.uk/cpdnboinc_cgi/cgi
2005-04-27 16:00:04 [climateprediction.net] Scheduler RPC to http://climateapps2.oucs.ox.ac.uk/cpdnboinc_cgi/cgi succeeded
