Win-7 64b, XFX HD6990, AMD 955BE 3.9GHz

BOINC version 7.0.3, ATI 12.1 Beta Catalyst Drivers

I discovered 7.0.3 is enforcing the CPU load thing. So, when I run Milkyway, it adds up the 0.80 CPU load and disables one core. A look at Task Manager shows this is not required since it is only 75% loaded.

I have no problems running any other tasks, but I used to be able to run Milkyway 0.82 with all 4 cores crunching other tasks.

Now, when I run Milkyway, I loose 25% of my crunching capability.

Could someone fix the 0.82 (ati) tasks so the CPU's is set to 0.08 instead of 0.80?

Thanks!

They have updated the server software. The server calculates the CPU-usage by himself. I don´t know the algorithm, but it leads to a false estimated CPU-usage. I have seen this at collatz after updating the server software. After that Jon hardcoded the CPU-usage for Collatz-tasks. IMHO I see two ways to resolve this issue:

1. hardcode real CPU-usage in the server code.
2. use an app_info.xml to adjust the usage by yourself.

Should be fixed.

Good grief... never such a fast reponse to a question/problem as here at Milkway!

The tasks run perfectly now without an app_info.xml..

Many thanks!!!!
