d.Open a terminal or graphic window and access the
e.Execute the command ./tsinstall in a terminal window. This program automatically detects the available kernel and installs the appropriate drivers as RPM packages. By default, topspin files are saved in the /usr/local/topspin directory.
#cdmount ./tsinstall
4.Configure the HCA drivers.
a.Configure the IPoIB driver by assigning an IP address to interface ib0 and/or ib1, which corresponds to the two HCA ports. IPoIB drivers load when the interfaces are used for the first time.
To assign ib interfaces, enter ifconfig ib#
Example of One HCA
#ifconfig ib0 192.168.0.0 netmask 255.255.255.0
#
#ifconfig ib1 192.168.0.1 netmask 255.255.255.0
Example of Two HCAs
#ifconfig ib0 192.168.0.0 netmask 255.255.255.0
#ifconfig ib1 192.168.0.1 netmask 255.255.255.0
#ifconfig ib2 192.168.0.2 netmask 255.255.255.0
#ifconfig ib3 192.168.0.3 netmask 255.255.255.0
a.(Optional) Configure MPI.
•Make sure that your connections to the HCA uses port 1 of the first HCA. MPI requires the use of HCA 1, port 1.
•Setup rsh or ssh on two nodes so that you can run commands between a remote and local node without entering a login or password. This is required to use the MPI protocol.
•Add paths to your environment PATH: /usr/local/topspin/mpi/mpich/bin /usr/local/topspin/bin
or
•Add the paths for all users by adding the following line to your /etc/profile.d script: export PATH=$PATH:/usr/local/topspin/mpi/mpich/bin:/usr/local/topspin/bin
b.Configure all other drivers, including SDP.
