Edgar Gabriel 2ec5fa5d24 - The component will remove itself from the list of potential collective
modules, if its priority is zero (the default value). Reason for that is
  + if there is no other module with a priority > 0, the hierarchical
    collective module has a problem anyway, since it has to rely on the coll
    modules of the subcommunicators. On the other hand, if its priority is
    zero, it won't be chosen anyway, and we can simply save the
    allreduce/allgather and comm_split operations which might occur during
    hierarchy detection.
  + to improve the startup times until we have the modex thing which we
    discussed with Jeff and Tim in Knoxville in place

- adding an mca parameter indicating a symmetric configuration. This can 
  speed up startup times, since each process can conclude from its data onto
  the data of the other processes -> no need for the allreduce operations. Per
  default  this parameter is set to "no".

coll_hierarch_tmpcoll.c further bugfixes. The hierarchy detection works now as far as I can see (even in unsymmetric sitations). Bcast and reduce work as well. Still to test: the code which generates new local leader communicators, in case the root of the operation is not yet part of the lleader comm. 2005-10-15 19:36:54 +00:00
