Topic Title: Atomic reads and writes to memory Topic Summary: Do AMD Athlon/Opteron behave similarly to Intel IA-32 with respect to atomic read/write operations Created On: 04/17/2008 08:06 PM Status:
Intel IA-32 architectures behave in a way such that a 32-bit write to a memory location that is aligned on a 32-bit boundary will be an atomic operation. I have not been able to confirm that this is also true on the AMD Athlon and AMD Opteron chips. Does anyone know if this is a safe assumption. Also, is there an AMD document that states this fact?
