VII. GM-1 Software Installation

GM-1 installation is performed in four easy steps:

1. Configuring and compiling GM-1.

2. Installing the GM-1 driver.

3. Running the GM-1 mapper.

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

For detailed installation instructions for GM-1 with FMS diagnostic monitoring, refer to

the FMS webpage (

http://www.myri.com/scs/fms/#install-tarball).

After you have completed these steps, proceed to Section VII. Testing/Validation (page

27).

1. Configuring and compiling GM-1.

Download GM-1

http://www.myri.com/ftp/pub/GM/gm-1.6.7_Linux.tar.gz

gunzip -c gm-1.6.7_Linux.tar.gz | tar xvf -

cd gm-1.6.7_Linux

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

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

make

If you would like to have FMS diagnostic monitoring with GM-1, refer to the FMS

Download page (http://www.myri.com/scs/fms/) for installation instuctions.

2. Installing the GM-1 driver.

Select an installation directory path <install_path>. It is usually best for <install_path>

to be the path to an NFS directory available on all machines that are to share this GM

installation. The directory must be accessible using <install_path> on all machines that

are to share the installation. <install_path> must be an absolute path; it must start with /.

However, <install_path> may contain symbolic links.

Note: The <install_path> installation directory must be created prior to invoking the

GM_INSTALL script.

cd binary

./GM_INSTALL <install_path>

If you omit <install_path>, the driver will be installed in the default directory, /opt/gm/.

Next, you must run

su root
