topoDebug
Select a virtual topology to return
Synopsis
int topoDebug(int kind)
Input Parameter
- kind
- Kind of topology to return.
Return value
0 on success, non-zero on failure.
Notes
Normally, the topo routines return information about the real topology
of the underlying hardware. However, this can make debugging programs
that want to make use of these routines difficult, since the tests would
have to be run on the target hardware system. This routine allows the
use of dummy, virtual topologies. Valid values for kind include:
kind = 1: Use a multiple of 8 processes, provide a Cray XE6-like
topology
