Even if pointer assignment is atomic, you have to consider cache coherency

my understanding is that cache coherency is taken care of at the hardware level and that only very low-level stuff like kernel drivers and such would need to worry about it.


this particular app would fall under the "multimedia" umbrella... video playback and such, but nothing kernel-deep.

knowing this, is it possible that pointer assignment will be effectively atomic even across multiple cores?

thanks.
