Chapter IV. iWARP (RDMA)

2.2. Compiling and Loading iWARP driver

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

will fail.

i. Change your current working directory to driver package directory & run the following

commands:

[root@host]# make

[root@host]# make install

ii. To load the iWARP driver we need to load the NIC driver & core RDMA drivers first. Run the

following commands:

[root@host]# modprobe cxgb4

[root@host]# modprobe iw_cxgb4

[root@host]# modprobe rdma_ucm

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