After implementing the DC_setcpu() as provided by Roger, the assignment of CPU core works, however, the assignment is based on the last CPU# saved in the file created. Therefore, it can end up with a situation where the same core is running for a few application when all application in other core qu...

I have removed all codes and left with very simple program as attached. You can build the exe and run it to see the runtime error.

Attached is x123.prg and x123.xpj.

Hi Tom There is no problem when I run from ..\Source\Samples\Solution\Smp. The problem arise only when I copy and paste the SMP code into my own program. When I remove the SMP code, my application run well. Once I add in the SMP code, runtime error occur. I am still using xbase 1.8 and express build...

I attach the print screen for the error.

Thanks Tom.

The error is function not defined. Nothing to do with the variable in DLL.ch. I don't know where is the function 'DllprepareCall'. In which library and why is it not defined if it is part of the system library.

DLL.ch is already included, otherwise error is 'unknown variable dll_cdecl'.
The error is function not declared for 'DllprepareCall'.

Thanks

Most other program automatically run on multiple core. Can anyone advise how to make xbase exe run on multi-core? Re...
