| Post subject: | Multicore processing |
Hello, I have tested version 7.31 with Win XP SP3 on a core i5 Computer. The effect is, that the load at the 4 cores is very different. The first core is near the maximum, while the others are at 20/30%. Multicore processing is switched on. What i´m doing wrong? Is there a way to better the load balance? Regards, Robert |

What i recommend you us to use "multicore". Also to set Stereo Tool to work only on 2. Reason is that ST anyways use not more then 2 cores, and also you will have another 2 cores totally free. This is for Windows7! Here is how to do it: You just need to edit your shortcut. - Right click on ST shortcut and hit "Properities" - In new window you should edit "Target" Usual ST target for XP is "C:\Program Files\Stereo Tool\StereoTool.exe" and for Windows7 "C:\Program Files (x86)\Stereo Tool\StereoTool.exe" - For XP put this as target "C:\Windows\System32\cmd.exe /C start "StereoTool" /affinity 3 "C:\Program Files\Stereo Tool\StereoTool.exe" Number 3 there determines on what cores will program work, so core 1 and 2. Don't get confused, cores are market as 0,1,2 and 3, meaning core 1,2,3 and 4. Here is list of possible combinations for quads. 1=Core 0 2=Core 1 3=Core's 0+1 4=Core 2 5=Core's 0+2 6=cores 1+2 7=cores 0+1+2 8=core 3 9=core's 0+3 10=core's 0+1+2+3 1a=core's 1+3 1b=core's 0+1+3 1c=core's 2+3 1d=core's 0+2+3 1e=core's 1+2+3 1f=core's 0+1+2+3 To check is this really work, open Tack Manager right click to StereoTool.exe process and click on "Set Affinity" You should see only core 1 and 2 checked. (0 and 1). |

Wow, thank you, i didn´t know this. But my Windows XP pro (german, SP3) doesn´t seem to know the /affinity" command. It says "unknown option "/affinity""... Do you have an idea? Or is this command only valid for Windows 7 If i right click the process stereotool.exe - affinity, all 4 cores (0-4) are checked. Is that coorect? |
