NUMA aware cache aligned memory allocation

In linux systems, pthreads library provides us a function (posix_memalign) for cache alignment to prevent false sharing. And to choose a specific NUMA node of the arhitecture we can use libnuma library. What I want is something needing both two. I bind certain threads to some certain processors and I want allocate local data structures for each thread from the corresponding NUMA node in order to decrease delay in memory operations for the threads. How can I do this?
