I will post a small example for testing.
It is interesting to note though that this happens only
when MPI_ALLREDUCE is called in a recursive kind of way.
Is there a possibility to limit the OMPI_free_list groth, via an --mca parameter ?

Subject: [OMPI users] OMPI_LIST_GROW keeps allocating memory
Content-Type: text/plain; charset=ISO-8859-15
using ompi 1.4.5 or 1.6.5 for that matter, I came across an
when an MPI function is called from in a recusivly called subroutine
the MPI_ALLREDUCE function allocates memory in the OMPI_LIST_GROW functions.
It does this indefinitly. In our case OMPI allocated 100GB.
is there a method to limit this behaviour ?
