Section:

C-2 Install Scali MPI Connect for TCP/IP

To install Scali MPI Connect for TCP/IP, please specify the -t option to smcinstall. No further configuration is needed.

C-3 Install Scali MPI Connect for Direct Ethernet

To install Scali MPI Connect for Direct Ethernet, please specify the -e option to smcinstall. This option has the following additional syntax :

-e<eth devs> : configures DET provider(s). Use comma separated list

for channel aggregation. Use multiple -e options for additional DET providers.

Example:

root# ./smcinstall -e eth0 -e eth1,eth2

The command in the example will create a DET device (det0) using Ethernet interface eth0 and then a DET device (det1) using eth1 and eth2 aggregated. Please not that aggregated devices usually require special switch configurations, for example separate switches for each interface channel or in some cases two different VLANs one for each channel.

C-4 Install Scali MPI Connect for Myrinet

To install Scali MPI Connect for Myrinet, please specify the -m option to smcinstall. This option has the following additional syntax :

-m<filenamepath>Install Scali MPI Connect for Myrinet. <filename> is gm-2.x source file package (.tar.gz) <path> is path to an exisitng gm installaton.

Examples:

root# ./smcinstall -m /home/download/gm-2.0.8_Linux.tar.gz

uses the GM source package /home/download/gm-2.0.8_Linux.tar.gz.

root# ./smcinstall -m /usr/local/gm

uses the GM installation in /usr/local/gm

When this option is selected SMC will default to Myrinet as the default transport device.

If this is not desired, modify the networks line in the global /opt/scali/etc/ScaMPI.conf configuration file. See chapter2.2 “SMC network devices” on page 12 for more information regarding network selection.

When SMC has finished installing all the required packages and an existing installation isn’t found, the Myrinet GM drivers will start to build. If the build process finishes successfully, it will install a package containing the relevant GM libraries, driver and binaries. The location of the libraries and binaries is /opt/gm, and the kernel driver is installed in the appropriate kernel module directory.
