[mpich-discuss] Get universe size no longer supported?

[Reuti]

Hi,

a call:

error=MPI_Comm_get_attr(MPI_COMM_WORLD, MPI_UNIVERSE_SIZE, &universe_sizep, &flag);

worked in MPICH2 1.4.1p1. But the "flag" returned unsupported in 1.5 and 3.0.2. Was this info removed from being retrieved?

PS: I found http://trac.mpich.org/projects/mpich/ticket/1426 mentioning MPI_UNIVERSE_SIZE but it throws an error:

TracError: The Trac Environment needs to be upgraded.

Run "trac-admin /www/trac.mpich.org/projects/mpich upgrade"
