CATC IBTrainer InfiniBand Exerciser, August 2002
Determining the Performance of
InfiniBand Traffic
The performance measurement counts values such as the size of
payload, the number of good and bad packets and the number of link
packets received and transmitted by the exerciser.
The two performance counters that hold the results of the performance
measurement are implemented in the software. For each counter, you
can separately determine which virtual lanes are to be monitored for
incoming and which VLs are to be monitored for outgoing packets.
Before starting the measurement, you must select the virtual lanes that
you want to monitor. Then you can start the measurement. When reading
out the measurement, the software displays following data in diagrams:
• The number of packets
• The payload and header data (in DWORDS)
• The payload data alone (in DWORDS)
• The number of link packets
• The accumulated values for each counter.
