Hi,

my Windows WS stalled on wu 40146072. I stopped it after 51,509.33 sec @ 50%.

https://universeathome.pl/universe/workunit.php?wuid=40146072

Afterwards it was processed easily by to Linux machines. In 5k an 3k something seconds.

Is there a bug in the windows code?

Kind regards,

Nikolas

I see 2 errors occured for your computer.
Each error says :
- Unhandled Exception Record -
Reason: Breakpoint Encountered (0x80000003) at address 0x00007FFBDECED162

Here is maybe a way to fix your problem.
It"s a tutorial which explores several different ways.
I advise you to try it.It may help you...
Good Luck.

Hi,

Thank you. Interesting.

I now decided to use Linux in future.

Just put ubuntu on a pen drive. Works twice as fast than under windows for my computer.

Kind regards,

Nikolas

I didn't understand what you meant when you questioned the windows code for crunching work units.
After seeing your performance on Linux, I ran another test.
I kept windows as the OS and installed a virtual machine with ubuntu in it just to see the difference in execution time. Here is a tutorial And incredibly, I get the same performance gains as you.(x2).
I understand better now the leaderboard ranking where the first places are given to linux.
I advise each windows cruncher to do the same.You'll spend less electricity to do the same amount of scientific work.
By the way , it seems there is maybe a difference between the linux distros.
The first 8 cores (40 nth) and the first 4 cores (46 nth) both run arch linux.This is maybe worth exploring further...for linux crunchers...

Thanks to have open my eyes.
