How to use all the processors (cores) on the PC when calculating the movement of the mill ?

PowerMill does not always use the whole CPU's power.

Anyway, this can help: ( I tried it on several PCs without any problem, it works, but it also can reduce your CPU's life. You do it at your own risk.)

How To Disable CPU Core Parking For Dual And Quad Processors:

1. Copy the following registry key entry between the brackets [ 0cc5b647-c1df-4637-891a-dec35c318583 ].
2. Select your start button.
3. In the search box, type ‘regedit’ and press enter.
4. Once your registry editor is open, select ‘Edit’ and ‘Find…’.
5. Paste the above registry key in the box and select ‘Find’.
6. Once it has located it, look for the keys on the right hand side labeled MinValue and MaxValue.
7. Double click on each value and make sure they are both set to ‘0’.
8. Select ‘Edit’ and ‘Find Next…’.
9. Continue to replace MinValue and MaxValue for each entry until you have replaced them all.
10. Close the registry editor and shut down your computer.
11. Power the computer back up.
12. Core Parking should now be disabled.

To check whether or not your cores are parked simply press ctrl + alt + del and open the task manager.  You can then select the ‘Performance’ tab and open the ‘Resource Monitor…’.  Within the resource monitor, select the ‘CPU’ tab and look at the graphs on the right hand side.  None of the CPUs should say, in text, that they are parked.  If they do not, then your processor cores are not parked.

I noticed about 7 % improvement with my tests.

Hello,

As far as I know, one PowerMILL session will only use a maximum of 4 logic CPU's. Even so, this depends on the kind of strategy used. Some are more prone to parallel processing than others.

In order to take full benefit of your PowerMILL license and your Intel Core i7 CPU, you should run at least two sessions in parallel, which is what most of our users do. Actually, performance is OK for up to 4 parallel sessions.

In case some forum member's didn't know: while under Delcam, a PM seat could run only two concurrent sessions. This limitation is gone under Autodesk, so you can open as many PM sessions as you wish.

Regards,

Vitor

The way PowerMILL works is that it will use 4 physical cores for a single toolpath calculation. So if you have a 8 core and which to to use all 8 you should "Queue" a toolpath and it will start calculation using 4 cores. Then create a another toolpath and use the "Calculate" button. This will then start another calculation simultaneously using another 4 cores. Doing this will leverage all 8 physical cores.
