We give an overview of the algorithms and implementations in the high-performance MPI libraries MPI/SX and MPI/ES of some of the most important collective operations of MPI (the M...
Abstract. An MPI profiling library is a standard mechanism for intercepting MPI calls by applications. Profiling libraries are so named because they are commonly used to gather p...

This paper describes a first approach to implement MPI-2’s Extended Collective Operations. We aimed to ascertain the feasibility and effectiveness of such a project based on exis...
Collective operations are an important aspect of the currently most important message-passing programming model MPI (Message Passing Interface). Many MPI applications make heavy u...
