ROCm also refers to them as warps https://rocm.docs.amd.com/projects/HIP/en/latest/understand/hardware_implementation.html https://rocm.docs.amd.com/projects/HIP/en/latest/understand/... : >The threads are executed in groupings called warps. The amount of threads making up a warp is architecture dependent. On AMD GPUs the warp size is commonly 64 threads, except in RDNA architectures which can utilize a warp size of 32 or 64 respectively. The warp size of supported AMD GPUs is listed in the Accelerator and GPU hardware specifications. NVIDIA GPUs have a warp size of 32.
