I am totally a novice in Multi-Core Programming, but I do know how to program C++.
Now, I am looking around for Multi-Core Programming library. I just want to give it a try, just for fun, and right now, I found 3 APIs, but I am not sure which one should I stick with. Right now, I see Boost’s MPI, OpenMP and TBB.
For anyone who have experienced with any of these 3 API (or any other API), could you please tell me the difference between these? Are there any factor to consider, like AMD or Intel architecture?
Under the hood OpenMP is multi-threaded programming but at a higher level of abstraction than TBB and its ilk. The choice between the two, for parallel programming on a multi-core computer, is approximately the same as the choice between any higher and lower level software within the same domain: there is a trade off between expressivity and controllability.
Intel vs AMD is irrelevant I think.
And your choice ought to depend on what you are trying to achieve; for example, if you want to learn TBB then TBB is definitely the way to go. But if you want to parallelise an existing C++ program in easy steps, then OpenMP is probably a better first choice; TBB will still be around later for you to tackle. I’d probably steer clear of MPI at first unless I was certain that I would be transferring from shared-memory programming (which is mostly what you do on a multi-core) to distributed-memory programming (on clusters or networks). As ever , the technology you choose ought to depend on your requirements.
