Direct communication between distributed gpus
WebThe results show that a global address space is best for applications that require small, non-blocking, and irregular data transfers, and that by using GPU optimized communication … WebThe above script spawns two processes who will each setup the distributed environment, initialize the process group (dist.init_process_group), and finally execute the given run function.Let’s have a look at the init_process function. It ensures that every process will be able to coordinate through a master, using the same ip address and port.
