1) Message boards : Cafe CPDN : Belgium, a small country with a great team: BOINC.BE (Message 33565)
Posted 2287 days ago by Profile Guy Pauwels
Today BOINC.BE entered the top 20 of all projects combined. A remarkable achievement for a team from a relatively small country like Belgium. With our recent average of over 600K/day we rank even higher, at position 16. This means that we can rise even further.

As a national team we only let 5 countries before us: the US, Germany, Canada, Australia and the Czech Republic. But we want to do better. We reach the vast majority of crunchers in the north of our country. We would like to launch a special appeal to our friends in the south to join our effort. Help us build a top team where all Belgians feel at home in a friendly, multilingual team and forum.
2) Message boards : Cafe CPDN : Belgian teams merge: Spacepage joins BOINC.BE (Message 31011)
Posted 2476 days ago by Profile Guy Pauwels
Team Spacepage has decided to join forces with Belgium\'s strongest DC team, BOINC.BE. The merge was announced in the Spacepage forum yesterday. Spacepage members will form a subteam within BOINC.BE, and can be recognized by the [SP] name tag. This will also allow them to participate in the internal subteam competition and team statistics. Spacepage promotes the use of BOINC for participation in scientific research. The new cooperation can contribute to the Spacepage initiative, by giving them access to the experience and contacts of Belgium\'s leading team.

Spacepage members can switch CPDN team using this link. To switch teams on all other projects, see this link.

Triple celebration at BOINC.BE

Bring on the crates of champagne. Boinc.be has reasons to celebrate.

- The team has reached the historic milestone of 100 million credits.
- Giorgio is now the number 1 cruncher in Belgium.
- We have risen to position 28 in the world ranking.

Great achievement, everybody. Keep filling those glasses.

I got the same error as John for this work unit: http://climateapps2.oucs.ox.ac.uk/cpdnboinc/result.php?resultid=6506855

The machine is running XP. It\'s got 2GB of RAM, and plenty of disk space. The model runs alongside either MalariaControl or Leiden.

I have no antivirus software installed, so the crash definitely was not the result of a virus scan in progress.

One thing worth mentioning about the work unit. It was only running for a couple of days. After about 40 hours CPU time, BOINC suddenly showed only 24 hours CPU time. The BOINC message log did not show any crash or stop/restart. But in task manager I saw that the process was only running for 3 hours, where it had ran non-stop since the start. Luckily (I thought) the current timestep had not dropped back, so I thought no work was lost. You can see this clearly in the work unit\'s trickle info.

The server would just ignore the repeated trickle and would start acknowledging trickles again from the first new one. (Says one who has restored from backups often!) However, if it crashes again in the same place, you\'ve probably got a looper :-( and should abandon it.


Thanks for reply. But it turns out this was a hypothetical question. I checked the backup. As this machine is no longer in production, it is also no longer included in our backup cycle. Pity.

What are the chances of success if I restore a backup from that directory? It has trickled about an hour before the error, and the backup is at least a day old. So the same trickle would be sent more than once to the server. Any idea what would happen?

Posted 2697 days ago by Profile Guy Pauwels
My work unit errored out after over 4100 hours and almost 80% complete. That\'s really too bad. What might have caused this? The machine was dedicated only to this project. No task switching, no new version installed, no Windows update. Just crunching happily and then the error :(

Posted 2780 days ago by Profile Guy Pauwels
It just means that the server routine to display the perturbed parameters is playing up...


Thanks, Mike. I will let it crunch happily into the new year then :)

Since a few days my cpdn results page is displaying a table of \'perturbed parameters\'. There is some mention in these boards of something similar, but I can\'t make out if it\'s worrying or not. Does it mean my model has gone to the dogs? Or should I just continue?

Perturbed Parameters for Result # 5276332
HadCM3L Coupled Model Experiment
Description Value Used Default Value Unit
ice fall speed 2.00000 1. m/s
ice fall speed 0.500000 1. m/s
etc...

The 2 largest Belgian teams BOINC.BE and Belgian MoOo Farm have joined forces. Together they will take on even bigger challenges and put Belgium on the Boinc map.

Belgian MoOo Farm lives on as a subteam of boinc.be, alongside BAT, boinc.be\'s special operations subteam. The subteams independently choose their course and can join the other subteams in their actions. Or take them on head-to-head in internal competions.

If you are from Belgium, or just like Belgians, come join us at http://climateapps2.oucs.ox.ac.uk/cpdnboinc/team_join_form.php?id=148. If you have an own Belgian team and would like your team to be part of our effort to put Belgium on the Boinc map, come talk to us in our forum at http://www.boinc.be/vbulletin.
