1) Message boards : Number crunching : Unrecoverable error after 4100 hours :( (Message 27907) Posted 14 Apr 2007 by mray Post: And finally - the reason it was stopped was that it was aborted 10 minutes before you posted. http://climateapps2.oucs.ox.ac.uk/cpdnboinc/result.php?resultid=6206053 <core_client_version>5.4.11</core_client_version> <message> aborted by user </message> <stderr_txt> I restored from backup and then aborted that, probably not the best idea but I already deleted the one that had the computation failure. I don\'t think it made much difference though, but it may affect stats concerning computation errors vs user aborted.
2) Message boards : Number crunching : Unrecoverable error after 4100 hours :( (Message 27883) Posted 14 Apr 2007 by mray Post: I just had one end with a computation error when it was in the mid 90s percentile. My last backup was at 83%. It was reporting some kind of file I/O errors. I had to really struggle to get the last one to complete, many restores. This time it\'s to far back and I abandoned it. My last WU was on a network drive, but I had this one on a local drive. I have no idea what caused the errors this time around. This was the first error it had, made it all the way to the mid 90s with no problem, then BANG. I\'m abandoning the project for now, maybe forever. They need to work on this thing more to break the WUs up more, a single run takes far to long right now and there are too many possibilities for errors. Backing it up myself is not a viable solution, BOINC is not supposed to require user intervention.
3) Message boards : Cafe CPDN : Supervolcano Docu/drama (Message 25285) Posted 25 Nov 2006 by mray Post: 2.1 million years ago, 1.3 million years ago, and 640,000 years ago. that implies an eruption is occuring approximately every 600 to 700 thousands years does it???? 2.1-1.3=0.8 last time I checked. Wouldn\'t it have been better to indicate something more like 550 to 900 thousand year gaps? Or is there some evidence to indicate that the gap will be less than than the 800k years between 2.1MYA to 1.3MYA? Maybe, maybe not. Three points do not a trend make.
4) Message boards : Number crunching : Is this worth restarting from backup? (Message 25146) Posted 16 Nov 2006 by mray Post: I\'m giving it one more shot and I will backup daily this time. I\'ve got way too many hours on this WU. I\'d still like to know what exactly the error means though. Was it a write failure to the HDD or the Internet? My systems fault or CPDNs or what?
5) Message boards : Number crunching : Is this worth restarting from backup? (Message 25144) Posted 16 Nov 2006 by mray Post: After going to 95% without problems I\'ve now had two crashes. First one was related to a network write error and I restarted from my backup. Lost 5 days of CPU time. Now, just as I passed the previous point and gained a few days it crashed again. I don\'t know what caused it this time. Here is a pic of the message log: The tasks panel says \"computation error\". Is this related to a write error on my side or CPDNs? Should I go back to the backup? It hasn\'t reported back yet apparently and I stopped the client just in case. I\'d hate to lose these many months of CPU time. It\'s the same backup I went to last time!
6) Message boards : Number crunching : What exactly did I join? (Message 22576) Posted 3 May 2006 by mray Post: I\'m strictly an independant cruncher :-) Thanx for the invite though.
7) Message boards : Number crunching : What exactly did I join? (Message 22551) Posted 2 May 2006 by mray Post: Seems like I\'m on the right track, I\'m runing the hadcm3lb 5.08 client. Was a little confused... Thx
8) Message boards : Number crunching : What exactly did I join? (Message 22545) Posted 2 May 2006 by mray Post: The URL I used was http://climateprediction.net, and I connected from my standard BOINC client which also runs SETI and Einstein. However, when I bring up the graphics its says \"BBC climate change experiment\". I thought that was a separate but related project? So, am I part of the BBC spinoff or the original program? Does it make a difference? Is there a difference? I tried to study before I joined, not sure it helped though :-(
