HOWTO: Building and configuring the Myrinet drivers

1. compile the source and install the myrinet driver on any of the nodes that contains a myrinet card and contains the linux-kernel source RPM.
• ./configure
• make
• cd binary
• ./GM_INSTALL /opt/gm
  
  
2. nfs export the myrinet build directory so the driver can be installed on other nodes with a myrinet card
   
• nfs export the build directory by adding entry to /etc/exports
• /export/gm-1.6.3_Linux              *(ro)                                 
• /etc/rc.d/init.d/nfs restart 
  
  
3. create a group in CSM for all nodes that contain a myrinet card
   
   
4. now run the following script against this node group
• dsh -N myrinet_group install_myrinet.sh BUILD_HOST:/BUILD_DIR
  
  
5. FIXME:  add info on running the GM Mapper in a HA environment
