iPerf is a tool for active measurements of the maximum achievable bandwidth on IP networks. It can be used to validate the throughput of the IP network path from an Isilon node to a compute node NIC. It can easily be scripted to run concurrently to allow all nodes to send or receive traffic.
FIO is a disk benchmark tool for Linux. It can be used to easily and quickly produce a storage workload that is nearly identical to the TensorFlow benchmark used in this document.
This section shows how to use iPerf and FIO.
To begin, on your head node (or first compute node), create a hosts file containing one host name (or IP address) per client. For example:
server1.example.com
server2.example.com
