Windows XP Support

The GM driver can be installed using the Device Manager. It can be reached by opening the System Control Panel applet and selecting the Hardware tab. The Myricom Myrinet Adapter should be listed as an unknown PCI device rooted off Other Devices. Right click on PCI device and select Properties to bring up the PCI Device Properties page.

Select Reinstall Driver... (even though no driver has been previously installed) to get to the Hardware Update Wizard. Choose to install from a list or specific location.

You will be prompted for the path to the driver files. Enter the path to the directory where the GM files have been installed and select Next >. Windows will spend some time searching for compatible devices and should find that the GM driver can be installed. Windows may complain that a digital signature has not been found for the driver. In this case, select Continue Anyway to continue with the installation.

The Myrinet mapper can be installed as a service that runs in the background or it can be run manually. The mapper service runs automatically when the system is booted and periodically remaps the entire network. Running the mapper manually is done with "gm_mapper_service active.args" or "gm_mapper_service map_once.args". The first invocation starts a mapper that runs forever, much like the server. The second invocation causes the mapper to map the network once and then terminate. The active.args file has comments describing the options that can be used for customization.

The installation of the mapper service begins from the Network Control Panel Applet.

Select the Local Area Connection that corresponds to the Myricom Myrinet Adapter. Right click on the icon and select Properties. From here, The Install... button allows the installation of various network components.

The mapper is a service, so select Service and then Add... Choose Have Disk... since this is not a service provided by Windows.

Select the active mapper and then complete the installation by pressing the OK button. The mapper will automatically run when the system is restarted. The mapper can also be manually started by executing "net start gm_mapper" at a command prompt.
