But because I am not an expert on alignment and memory optimization, I will try to use something "more standard", actually I am going trying to use the allocator to compute the "right" address to place an object of a given type that is greater that a "free" memory pointer. In that way, I also expect to take advantages of allocator such as tbb cache aligned allocator.
I know nothing about how 'to use the allocator to compute the "right" address'; hence, I'm afraid I can't be any help there. Could you maybe give a brief summary of how that works?
No idea, I was just speculating, actually, I am not sure I will be able to do it. On the other hand, I suppose there should be a way to do it. Just need some time and thought.
Allocator itself is not suitable for determining object address. Its interface is tailored for allocating objects and arrays of objects of the same type. If you want something more elaborate, you have to implement it yourself, I'm afraid. I might add that you're treading on the memory management field. This can be a rather complicated matter, which deserves a dedicated library, IMHO. Things like efficient (both in terms of space and time) allocation strategies and dealing with fragmentation are point of a serious research, which is in most part beyond a container library. The container should allocate memory in the way most suitable for the intended use of the container. It is the allocator's job to perform these allocations efficiently. So, my advice would be to focus on the container interface design first.
