# mount /mnt/cdrom

An integrated suite of drivers is provided, including IPoIB, SRP, SDP, uDAPL and MPI .

a.Make sure your Linux kernel is supported. Contact the Technical Support website at http://www.topspin.com/support/

b.Insert the supplied CD-ROM into the CD-ROM drive. The CD-ROM is provided in the box with the Switched Computing system.

c.(Optional) Mount the file-system for the CD-ROM drive if your platform does not auto-mount devices.

d.Open a terminal or graphic window and access the top-level directory on the CD-ROM

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.

# ./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# ip address netmask netmask:

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.

•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

•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.

Refer to the Host Channel Adapter Installation Guide for instructions.
