Multi-core support since AS\AR V6.1
Automation Studio V6.1 is released in December 2024.
Together with Automation Runtime 6.1 this enables multi-core support.
Already a lot of current cpu’s are multi-core, but until now only one core was used for AR.
In AS V6.1 on a multi-core cpu a process (background task) can be assigned to the extra core(s).
This results in more performance for the core assigned to AR.
On a dual-core cpu, which contains a powerlink interface, the powerlink stack is always assigned to a core.
Examples : X20CP0482, X20CP0483, X20CP0484, 4PPC50.101E-10B.
On a dual-core cpu without a powerlink interface the extra core could be used for the OPC UA stack/communication.
Examples : X20CP0410, X20CP0411
This is also the case for quad-core cpu’s like X20CP3687X and 5APC2200.AL18-00.
In the AsArProf library extra function blocks are added to read out the number of cores and the load on these cores.
- CpuGetNumberOfCores()
- CpuIsCoreReserved()
- CpuGetLoadByCore()
Example program
CASE Step OF
0:
NumberofCores := CpuGetNumberOfCores();
IF ((NumberofCores > 0) AND (NumberofCores <5)) THEN
FOR i:=0 TO (NumberofCores-1) DO
CoreReserved[i] := CpuIsCoreReserved(i);
LoadByCore[i] := CpuGetLoadByCore(i);
END_FOR
END_IF
Step := 1;
1:
;
END_CASE
Another background task is for instance mapp Robotics.
This SMP support for mapp Robotics is featured in mappMotion 6.2. (Release in March 2025)
