TCI is an interface for creating and organizing teams of threads. It uses a communicator model, similar to MPI, where threads synchronize and share data through a handle (the communicator) to a shared state object (the context). Communicators may be split into smaller sub-communicators for hierarchical parallelism, with independent synchronization and communication.
Threads may be initially created using the tci_parallelize construct, which blends pthreads-style thread creation with semantics similar to OpenMP parallel blocks. Alternatively, thread contexts may be created ad-hoc and thread communicators joined as needed.
A C++11 interface is also available that provides convient template and object-oriented wrappers.
