Hi
after running a module for 198 hours and over 51% completed I got a computation error. I have uploaded it but was there anything else I could have done and is it worth getting a new one to do
thanks Paul

Hi Paul, welcome to CPDN.

Although HadSM3H models are sometimes prone to crashes, there is nothing obvious with your crash. Others have got further.

I would recommend that you read the \"Information of running the climate models\" here. The \"README - Crashes and other problems\" has a wealth of guidance README here on avoiding crashes. CPDN programs/models do stress the hardware so much more than the other programs you are running, so I would suggest that you run a stability test using PRIME95 (description and link in the hardware section of the readme) for 24 hours. This will check for problems that could be instability in your setup.

I see you have downloaded a new model to run. Welcome again and good luck.

Hi, Paul

After checking the stability of your system you should learn how to make backups. They don’t take long, (only about 5 minutes) and they guard against disaster. I make one every morning. Once you have a recent backup the occasional model crash becomes nothing but a minor annoyance. Doing a restore take even less time than making the backup. It can prevent the loss of hundreds or even thousands of hours of computer time. I hope this one setback doesn’t cause you to give up on project.

Hi
many thanks

I have a few questions
I have found the BOINC folder but this just seems to have the main BOINC files and nothing dated earlier than 2 weeks ago
I have done a search for a file name with Climate in it and it did not find anything. I did a search on hadam and it found 3 files in C:windows:prefetch
so I am not sure what to backup as doing windows prefetch seems risky.
thanks for any advice
regards Paul

With version 6 of BOINC, the program was split into 2 parts;
1) Program
2) Data

The part that needs to be backed up is the Data part.
There\'s info about version 6 here

But if you specified a different location for the data, then it\'s up to you to remember where.

Also, Windows normally sets the area used for the default location to hidden.
You\'ll need to look at
Tools -> Folder Options -> View (In Windows Explorer), and check the setting for
Hidden files and folders
