After 6 years of work, the MPI Forum has released version 4.0 of the Message Passing Interface (MPI) Standard. New features include persistent collectives, partitioned communication, MPI Sessions, a new tool interface, better error semantics, improved support for hardware topologies and more. The standard is available on the MPI Forum webpage.
Prof. Schulz chaired the MPI forum during the creation of this standard and was re-elected to also lead the efforts towards MPI 4.1.
