2. Software/Driver Loading

2.1. Compiling and Loading iWARP driver

The driver must be loaded by the root user. Any attempt to load the driver as a regular user will

fail.

 Change your current working directory to driver package directory and run the following

command :

[root@host]# make

[root@host]# make install

 To load the iWARP driver we need to load the NIC driver and core RDMA drivers first. Run

the following commands:

[root@host]# modprobe cxgb4

[root@host]# modprobe iw_cxgb4

[root@host]# modprobe rdma_ucm

 Set Chelsio driver option for MPI connection changes. Run the following command on all

systems:

[root@host]# echo 1 > /sys/module/iw_cxgb4/parameters/peer2peer
