Re: [Gems-users] Thread migration in Gems

[Dan Gibson <degibson@xxxxxxxx>]

If your work relies on having system-level effects of migration, I recommend you have a second thread in your application explicitly bind to cpu0 while your 'main' thread is doing work. You can even semi-synchronize the event with a CV if you so choose.

I would NOT suggest modifying CPU registers directly.

Hi Gems users

 

I want to migrate my test program from core 0 to core 1 in a x86 dual core system.

Can I do this by changing the CPU context directly?

For example, stall these two CPUs -> read all registers values from core 0 -> write these values into core 1 -> unstall core1
