CUDA Supports: ¡ Thread parallelism § each thread is an independent thread of execution ¡ Data parallelism § across threads in a block § across blocks in a kernel ¡ Task parallelism § different blocks are independent § independent kernels executing in separate streams 14/73
Synchronization ¡ Threads within a block may synchronize with barriers … Step 1 … __syncthreads(); … Step 2 … ¡ Blocks coordinate via atomic memory operations §e.g., increment shared queue pointer with atomicInc() ¡ Implicit barrier between dependent kernels vec_minus(a, b, c); vec_dot(c, c); 15/73
