cleanup msg actions + MPI stuff is deprecated, no need for so much example files + keep it though for illustrative purposes
reimplement reduce and bcast (non tested) w/o spawns uncomment the comm_destroy modify the action files to add init and finalize git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/simgrid/simgrid/trunk@9058 48e7efb5-ca39-0410-a469-dd3cf9ba447f
Repair collective operations (changes made for asynchronous end to end communications had a bad impact) !!! WARNING !!! In order to save space the arbitrary choice changed. The processes now have to be named p0, p1, ..., pN instead of process0, process1, processN The resulting gain becomes impressive for large traces. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/simgrid/simgrid/trunk@7055 48e7efb5-ca39-0410-a469-dd3cf9ba447f
First implementation of allReduce action (Refactoring will be needed at some point) All involved processes exit at the same time git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/simgrid/simgrid/trunk@6833 48e7efb5-ca39-0410-a469-dd3cf9ba447f
add a flat broadcast action requires a comm_size action to set the size of the MPI_COMM_WORLD communicator update the actions_with_isend.txt to include the Isend action git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/simgrid/simgrid/trunk@6823 48e7efb5-ca39-0410-a469-dd3cf9ba447f
