[OMPI devel] two questions about 1.7.1

[Paul Kapinos]

Hello All,

I.
Using the new Open MPI 1.7.1 we see some messages on the console:

> example mpiext init
> example mpiext fini

... on each call to MPI_INIT, MPI_FINALIZE at least in Fortran programs.

Seems somebody forgot to disable some 'printf'-debug-output? =)

II.
In the 1.7.x series, the 'carto' framework has been deleted:

> - Removed maffinity, paffinity, and carto frameworks (and associated
>   MCA params).

PROGRAM PK_MPI_Test_2

USE MPI
IMPLICIT NONE
!include "mpif.h"

INTEGER :: ierr

CALL MPI_INIT (ierr)
CALL MPI_FINALIZE(ierr)

END PROGRAM PK_MPI_Test_2

! ?????
! $ ./a.out 
! example mpiext init
! example mpiext fini

Is there some replacement for this? Or, would Open MPI detect the NUMA structure of nodes automatically? Background: Currently we're using the 'carto' framework on our kinda special 'Bull BCS' nodes. Each such node consist of 4 boards with own IB card but build a shared memory system. Clearly, communicating should go over the nearest IB interface - for this we use 'carto' now.
