Supported iWARP Applications
Linux-supported RDMA applications for iWARP include the following:
ibv_devinfo, ib_devices
ib_send_bw/lat, ib_write_bw/lat, ib_read_bw/lat, ib_atomic_bw/lat
For iWARP, all applications must use the RDMA communication manager
(rdma_cm) using the
-R
option.
rdma_server, rdma_client
rdma_xserver, rdma_xclient
rping
NFS over RDMA (NFSoRDMA)
iSER
Running Perftest for iWARP
All perftest tools are supported over the iWARP transport type. You must run the
tools using RDMA connection manager (with the
-R
option).
Example:
1.
On one server, issue the following command:
#
ib_send_bw -d qedr1 -F -R
