ipathbug-helper

The tool ipathbug-helperis useful for verifying homogeneity. Prior to seeking assistance from QLogic technical support, you should run this script on the head node of your cluster and the compute nodes which are suspected to have problems. Inspection of the output will often help you to see the problem. Simply run it on several nodes and examine the output for differences.

It is best to run ipathbug-helpermakes requires it. There is also a of gathered information.

with root privilege, since some of the queries it which greatly increases the amount

If you are unable to see the problem, send its stdout output to your reseller, along with information on the version of the InfiniPath software you are using.

C.9.11

ipath_pkt_test

This is a simple program that can be used to test the InfiniBand link and bandwidth between two InfiniPath HCAs, or, using an InfiniBand loopback connector, within a single InfiniPath HCA. It is runs in either ping-pong mode (send a packet, wait for a reply, repeat), or in stream mode (send packets as quickly as possible, receive responses as they come back).

On completion, the sending side prints statistics on the packet bandwidth, showing both the payload bandwidth, and the total bandwidth (including InfiniBand and InfiniPath headers). See the man page for more information.

C.9.12

ipathstats

The ipathstats program can be useful for diagnosing InfiniPath problems, particularly those that are performance related. It displays both driver statistics, and hardware counters, including both performance and "error" (including status) counters.

Running "ipathstats -c 10", for example, will show the number of packets and 32 bit words of data being transferred on a node in each10 second interval. This may show differences in traffic patterns on different nodes, or at different stages of execution. For more information see the man page.
