1) Message boards : Cafe CPDN : BOINC projects? (Message 38234)

Ahoy, shipmates!

Came to think about various BOINC uses. I am participating in two projects: SETI@home and Climateprediction.net. The first one is fascinating considering the philosophical consequences of the issue. The second one is related to one of our most pressing global—planetary, if you like—problems for the time being.

There certainly are many other laudable BOINC based operations as well, see e.g. http://boinc.berkeley.edu/projects.php. Also: climate change is one of our most pressing global problems, but I didn’t say the only one. In some of those other problems no BOINC might be able to help the least bit at any case, but in some others no doubt it can. And of course the good Climateprediction.net project alone is not sufficient either, but let’s hope the December Copenhagen summit will be most successful.

However all this for the purpose of this message now, I sometimes feel tempted to attach my BOINC application to some more projects, too. Yet so far have always decided to keep concentrated into those two.

How have you other guys chosen and decided about your BOINC projects? Of course, as I am sending this message to a SETI@home forum and a Climateprediction.net message board, I am pretty sure most of you run one or the other of those. But what else perhaps, and based on which reasoning?

Hello, shipmates!
Before trying to download new work from CPDN be sure that you have no CPDN models suspended.
Yes, sure. But the thing is, as follows.
* One HADAM3P running, almost 30 % progress, says about 850 hours to completion; I believe will be much less eventually.
* Another HADAM3P suspended at 6,8 %. I shall allow this to run again after the first one is completed. Also, the Climate Prediction project is presently told not to get new tasks for me; it will be let to do so again when this second job is finished.
* At the same time SETI work units are now again able to be downloaded, ran and reported with no problem; this was not the case with this BOINC version 6.6.36, if I allowed two HADAM3Ps to run simultaneously.

So, a bit more monitoring is required than usually, but no big deal. Hopefully later BOINC versions indeed will have a fix to the bug on the bottom of this, as Richard Haselgrove said earlier in this thread.

It's possible that your last CPDN Model(s) ran in priority mode to meet the "deadline", keeping other Projects from getting time.

Yes, could be of course, but my both present CPDN work units have their "report deadline" in early July 2010 only. I have now one of those running, the other one suspended, and a SETI job is being computed by the other processor. So basicly this is as I want it to be, only that a bit more monitoring is required than usually. I may have to make sure personally, that new work units are able to be downloaded from time to time.

A different thing is, that after latest updates my BOINC application seems to overestimate running times remarkably. It thinks e.g. a new CPDN HADAM3P 6.06 toil would take about 1800 hours, when about 500 is nearer to the final outcome.

Hello, shipmates,

Experienced a minor technical problem – seemed one project work units running on my present BOINC 6.6.36 version prevented the thingamajig from downloading jobs from another. The start and happy end of the story, for your kind information:

http://setiathome.berkeley.edu/forum_thread.php?id=54764&nowrap=true#921044

I am glad to be able to tell, that at the moment my BOINC is happily munching both projects toils again.

Good June!

This present technical problem with CPDN system irritated me slightly in the beginning: "Why don't these guys take necessary steps in advance...?"

However, I soon calmed down as remembered an old story from my country. There was a certain extremely high ranking military officer, Marshal of Finland C. G. E. Mannerheim, who was the Commander-in-Chief in all Finnish wars last century. It seems, that sometime during WWII, when he was doing some travelling, his car broke down. The discussion was something, as follows.
"Driver, why didn't you take this vehicle to workshop in time?"
"Sir, do you take your watch to clocksmith before it stops?"
A long pause ensued..., then with different tone...
"No, actually, I don't..."
