These are the building blocks for the implementation of applications with Readers \& Writers semantic, like for example distributed hash tables. This paper discusses the implementation of MPI passive target synchronization on a non-cache-coherent multicore, the Intel Single-Chip Cloud Computer. The considered algorithms differ in their communication style (message based versus shared memory), their data structures (centralized versus distributed) and their semantics (with/without Writer preference). It is shown that shared memory approaches scale very well and deliver good performance, even in absence of cache coherence.}, language = {en} }
