Hi all, I would like to know how do the IB atomic operations work and how much can one rely on them? Particularly, how does the interaction with the CPU takes place when for example the CPU is referencing and possibly modifying the same address, atomically . Does one need to take care of memory say, with memory barriers? Does anyone has experience with this? There must be also different hardware support from the vendors, right?
I hope I'm not sounding too vague, I'm not such a kernel or hw guy. I tried to look for information on this but found pretty much nothing. Can the experts shed some light on the problem?
