Web1.6 Primitives for distributed communication source from which the data is to be received (this could be a wildcard), and the user buffer into which the data is to be received. There are two ways of sending data when the Send primitive is invoked – the buffered option and the unbuffered option. WebMar 23, 2024 · However, in the distributed training of large model, pure set communication mode is adopted more directly because the unified update of single point parameter server is reduced. In deep learning framework, communication primitives of distributed training and communication implementation mode play a very important role in distributed …

WebMPI stands for Message Passing Interface. MPI is used to send messages from one process (computer, workstation etc.) to another. These messages can contain data ranging from primitive types (integers, strings and so forth) to actual objects. MPI is only an interface, as such you will need an Implementation of MPI before you can start coding.
