The simpleCUDAGraphs sample shows the migration of simple explicit CUDA* Graph API's such as cudaGraphCreate, cudaGraphAddMemcpyNode, cudaGraphClone, etc., to SYCL equivalent API's using Taskflow programming model which manages a task dependency graph. The original CUDA* source code is migrated to SYCL for portability across GPUs from multiple vendors.

Key Implementation Details

SYCL simpleCUDAGraphs sample performs a reduction operation to obtain the sum value from 16777216 number of elements in two different computational kernels reduce() and reduceFinal(). These kernels are scheduled through taskflow which develops a simple and powerful task programming model to enable efficient implementations of heterogeneous decomposition strategies and leverages both static and dynamic task graph constructions to incorporate computational patterns.
