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
