Implementation of MPI on Fujitsu AP1000 <contact>David Sitsky (David.Sitsky@cs.anu.edu.au) <abstract> Work is currently being done to implement MPI on the Fujitsu AP1000 on top of the native message passing routines provided by the CellOS operating system. The operating system has been modified to directly support MPI contexts and provides a powerful selective broadcast operation which is used to implement many of the collective and communicator constructor functions. Currently, release 1.4 of the software is available. <description><url>ftp://dcssoft.anu.edu.au/pub/www/dcs/cap/mpi/mpi.html</url> <keywords>message passing library; MPI; architecture dependence <category>ppt-comm </urc>
