Here is a forum thread that tries to explain, why it can lead to problems and decreased performance when there are too many CEP2 workunits running simultaneously on one computer.

We had a maintenance session on jabba1 today - turns out that one of the PCI cards seems to have gone bad. No big issue.

Here is another forum thread which discusses what happens, when a calculation does not converge, und what that means in the first place.

Another two milestone passed: We have now collected over 6,000 years of computing time and 7 million primary results! How cool is that?

I have had an issue occasionally, not sure if it was a bad data set or what, and it was not just unique to CEP either, but the drive would start 'tinking' ie thrashing, and sure enough give it about a minute or two and blue screen.
At first I thought it was possibly a bad spot on the drive, but after extensive tests, find out it is just .. probably a windows thing. (gee go figure), the task aborts and everything is back fine. One thing I found that helps is to set in advanced / disk memory use / set checkpoint at most every 300 seconds or more, instead of the normal 30 or 60 is it? This seems to save a lot of wear and tear on the drives I find. On a similar note, I have fufilled my obligations on another project and am back to crunching CEP now along with another project. In a few months once I hit 2 years on the other project, unless something else new comes up, I foresee running CEP primarily on my machines. Too bad there isn't a CUDA app for CEP, id be flying then!! Aaron |

Have you run windows defender and see if the blue screen is caused by some third party program?
Had similar blue screens and running windows defender twice found a program and upon removal of the third party program the blue screens ceased to occur. Took windows defender twice to remove all traces of the program. |
