HP-MPI V1.1 for Windows Release Note

Myrinet MX setup

Select Reinstall Driver (although no driver has been previously installed). This will

initiate 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

MX files are installed and select Next. Windows will search for compatible devices and should

find that the MX driver can be installed. You may receive a message that a digital signature

has not been found for the driver. Select Continue anyway.

Installing the Myrinet mapper

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 mx_mapper or

mx_mapper --map-once. mx-mapper starts a mapper that runs forever, much like the server.

mx_mapper --map-once causes the mapper to map the network once and then terminate.
