cmpxchg16 / c10kpp Goto Github PK

The goal of that project is to provide a research on network server programming approaches to solve the c10k problem (c100k...cNk as well). The programming approaches we will inspect:

• Native thread per socket (synchronous handling)
• State machine based on epoll (native thread per core, asynchronous handling)
• Green thread per socket (codenames: Coroutine/Fiber) (native thread per core, synchronous handling (asynchronous under the hood))

• gcc 4.7 ++ (or anything else that support rudimentary C++11)
• boost 1.49
• autoconf and automake

1. Run autoreconf -i to create the configure script.
2. Optional: Create a directory for the specific variant, e.g.: mkdir build_noaffinity. Change into it.
3. Run configure from the source dir. For the example in 2 above, run ../configure --disable-affinity.
4. make.
