These programs demonstrate Uni20's epoch-ordered async runtime from basic Async<T> expressions through TBB execution, Tensor kernels, failures, and DAG diagnostics.

Fundamentals

async_example.cpp: basic reads, writes, try_await, and scheduler progress.
async_example2.cpp: interactive expression graphs, assignment/rebinding, and stepping DebugScheduler one task at a time.
async_ops_example.cpp: expression-DAG composition and all(...).
async_buffer_semantics_example.cpp: read/write ownership, release ordering, cancellation, and exception routing.
async_buffer_await_paths_example.cpp: borrowed and owning value, storage, and consuming await paths.
future_example.cpp: a graph blocked on FutureValue until late fulfillment.

Kernel And Scheduler Shapes

async_kernel_shapes_example.cpp: equivalent compact-expression and explicit captureless-coroutine implementations.
async_tensor_matrix_product_example.cpp: async Tensor matrix-product overwrite and update through normal kernel dispatch.
async_tbb_matrix_product_batch_example.cpp: configurable parallel Tensor GEMM batch with scheduler concurrency, backend, and precision selection.
async_tbb_reduction_example.cpp: paused construction and parallel TBB execution of a map/reduction tree.
async_fib_example.cpp: recursively scheduled Fibonacci DAG on TBB.
async_ad_stress_example.cpp: configurable AD/dataflow stress workload with dead and failing branches.

DAG And Failure Diagnostics

async_dag_debug_example.cpp: basic task-registry Graphviz capture.
async_dag_gallery_example.cpp: branching, kernel-shape, and lifecycle DAG snapshots.
async_dag_deadlock_tbb_example.cpp: deliberate TBB dataflow deadlock and diagnostic snapshot.
async_diagnostics_guide_example.cpp: presentation-layer guide to registry reports, stacktrace capability, Graphviz output, and runtime controls.
async_coroutine_failure_example.cpp: deliberate coroutine failure propagated through writer boundaries, with optional automatic Graphviz capture.

The deadlock and coroutine-failure examples intentionally exercise failure paths. See the examples index, Async Documentation, Async Kernel Authoring, and DAG Debug Examples.
