[dpdk-users] Is DPDK compatible with C++11 threads?

[Pavey, Nicholas]

Yes, agreed. We only use the STL in general purpose code, not the DPDK fast path.

Also look at one of the DPDK examples as it uses a lthread on top of pthreads and it may give you some ideas as to how multiple threads can work. I am trying to remember which example and my dev machine is down at this time, but just search for lthread.

one more thing that you probably need to watch out for would be libc interactions within your C++11 application e.g. usage of stl containers might exact a severe performance penalty...
