Scalability of communicators and groups in MPI

  title={Scalability of communicators and groups in MPI},
  author={Humaira Kamal and Seyed M. Mirtaheri and Alan Wagner},
As the number of cores inside compute clusters continues to grow, the scalability of MPI (Message Passing Interface) is important to ensure that programs can continue to execute on an ever-increasing number of cores. One important scalability issue for MPI is the implementation of communicators and groups. Communicators and groups are an integral part of MPI and play an essential role in the design and use of libraries. It is challenging to create an MPI implementation to support communicators… CONTINUE READING
