3. Enabling IP over Myrinet (Ethernet emulation) (OPTIONAL)

If you wish to run IP over Myrinet (ethernet emulation), the Linux command to enable IP

over MX is as follows:

/sbin/ifconfig myri0 <ip_address> up

where you must replace myri0 with the appropriate name (myri1, myri2, etc.) if you have

more than one Myrinet NIC per host.

VI. GM-2 Software Installation

GM-2 installation is performed in three easy steps:

1. Configuring and compiling GM-2.

2. Installing the GM-2 driver.

3. Enabling IP over Myrinet (ethernet emulation) (OPTIONAL)

For detailed installation instructions for GM-2 with FMS diagnostic monitoring, refer to

the FMS webpage (http://www.myri.com/scs/fms/#install-tarball).

These installation instructions assume that your cluster is not diskless. If you have a

diskless cluster, please contact help@myri.com for the proper installation procedure. We

currently recommend GM-2.0.26_Linux for clusters with PCIXD or PCIXF NICs, and

GM-2.1.26_Linux for clusters with PCIXE NICs. For full details, please refer to

http://www.myri.com/scs/#downloads. For purposes of this document, we will only

discuss the installation of GM-2.0.26_Linux. The installation of GM-2.1.26_Linux

follows the same procedure. After you have completed these installation steps, proceed to

Section VII. Testing/Validation (page 27).

1. Configuring and compiling GM-2.

Download GM-2

http://www.myri.com/ftp/pub/GM/gm-2.0.26_Linux.tar.gz

gunzip -c gm-2.0.26_Linux.tar.gz | tar xvf -

cd gm-2.0.26_Linux

./configure --with-linux=<linux-source-dir>

make

where <linux-source-dir> specifies the directory for the Linux kernel source. Note that

as of GM-2.0.15 and later, if the --with-linux= option is not specified, the default is

"/lib/modules/`uname -r`/build". This is the default location used by all major

distributions. The default in previous releases of GM was /usr/src/linux/.
