    Guys, I must be really smart. If you want to run PI Segment at one core simply set your cache to 1 WU every time the agent will fill op your cache. This mean the second core gets the status “waiting”. I have test it because i want to se what happen when the WU was finished if it should change core but it never happen. On core is occupied by D2OL.

    Since I think D2OL do not set the affinity of CPU, you can try to do following operations to balance the resources:

    1. Close Pi Segment
    2. Open "config.ini" by notepad
    3. Find [P0] and [P1] section and change them to
    [P0]
    Init=1
    Enable=1
    Affinity=3
    [P1]
    Init=0
    Enable=0
    Affinity=0
    4. Save the file and run Pi Segment again. Then Windows will balance the two cores to Pi Segment and D2OL

    I see now my smart solution wasn’t so good. It seems as PI Segment and D2OL had chare the same core. One core use 100 % of its recourse and eOn the other core with less recourse. PI is now calculating faster. If I run eOn it will slow down PI. I thought if I ran D2OL and the started PI it automatic should feel which core as was free.

    Try switching P0 off and leave P1 on. That way, D2OL should use core #1, then PI Segment will use Core #2.

    Any as remember the settings for Init, Enable and Affinity if I will run both cores? I forgot write it up before I change settings.

    This is from my config.ini

    Code:
    [P0]
    Init=1
    Enable=1
    Affinity=1
    [P1]
    Init=1
    Enable=1
    Affinity=2
