ibnd_discover_fabric: initialize ibnetdiscover library.
NAMEibnd_discover_fabric, ibnd_destroy_fabric, ibnd_debug ibnd_show_progress - initialize ibnetdiscover library.
#include <infiniband/ibnetdisc.h> void ibnd_destroy_fabric(ibnd_fabric_t *fabric) void ibnd_debug(int i) void ibnd_show_progress(int i) int ibnd_set_max_smps_on_wire(int i)
DESCRIPTIONibnd_discover_fabric() Discover the fabric connected to the port specified by ibmad_port, using a timeout specified. The "from" and "hops" parameters are optional and allow one to scan part of a fabric by specifying a node "from" and a number of hops away from that node to scan, "hops". This gives the user a "sub-fabric" which is "centered" anywhere they chose.
ibmad_port must be opened with at least IB_SMI_CLASS and IB_SMI_DIRECT_CLASS classes for ibnd_discover_fabric to work.
ibnd_destroy_fabric() free all memory and resources associated with the fabric.
ibnd_debug() Set the debug level to be printed as library operations take place.
ibnd_show_progress() Indicate that the library should print debug output which shows it's progress through the fabric.
ibnd_set_max_smps_on_wire() Set the number of SMP's which will be issued on the wire simultaneously.
RETURN VALUEibnd_discover_fabric() return NULL on failure, otherwise a valid ibnd_fabric_t object.
ibnd_destory_fabric(), ibnd_debug() NONE
ibnd_set_max_smps_on_wire() The previous value is returned
Discover the entire fabric connected to device mthca0, port 1.
Discover only a single node and those nodes connected to it.
