Generic Workflow

Below is a generic flow for using C++ API of oneCCL:

1. Initialize the library:

   ccl::environment::instance();
   

   Alternatively, you can create communicator objects:

   ccl::communicator_t comm = ccl::environment::instance().create_communicator();
   

2. Execute collective operation of choice on this communicator:

   auto request = comm.allreduce(...);
   request->wait();
