Hello,

I keep getting "Computation errors" after 1-2 seconds on BOINC. Here is an example of the task output. I do not know where to start in thsi error output to find out what is going wrong.

Did these errors just start? Any recent changes to your hardware or OS?

You can try deleting and re-adding the project maybe? Might need to delete or move the files in your BOINC data directory.

Hello
I have an Amd Radeon 380X graphic card and I have lot's of computation errors almost 50%
Once again It seams that this project has unsolved computation issues on amd/ati graphic cards.

The team of this...so called "project" is probably not up to the task for fixing their own issues with graphic card computation. It is happenning very often, I mean very very often!

So it's a shit project for me !
I won't waste computation time and electricity on Milkyway anymore despite my respectable score and history.

If, like me you have lot's of computation errors with this...?project?
Crunch on Einstein at home wich is issue and error free !

Sincerly

Check your drivers, they don't appear to have been recognized by Boinc.
