SWARM has been introduced as an open source parallel programming framework. It is a library of primitives that fully exploit the multicore processors. SWARM is built on POSIX threads that allow the user to use either the already developed primitives or direct thread primitives. SWARM has constructs for parallelization, restricting control of threads, allocation and de-allocation of shared memory, and communication primitives for synchronization, replication and broadcasting. The framework has been successfully used to implement efficient parallel versions of primitive algorithms. Viz. List ranking, Prefix sums, Symmetry breaking, etc. SWARM is available for Linux, FreeBSD, Solaris, AIX, and Microsoft Windows.
