Myrinet2000 Switch Configurations

The Easy Installation Tool automatically creates a Myrinet 2000 switch configuration file for PM/Myrinet. Myrinet2000 switches are built from switch enclosures(E16, E32, E64, and E128), Line switch cards(SW16) and SPINE cards(SPINE). In order to build Myrinet2000 or Myrinet XP cluster, after you recongnize your switch hard ware, lease connect the Myrinet network using one of the following allowed connections: If you want to build a cluster of more than 128 compute hosts, please contact us using SCore Users ML.

Myrinet2000 SAN switch:

When you use Myrinet2000 SAN switch, please be sure jumper switch on line switch card: speed setting and HA feature. When you use SCore,the default setting for HA feature must be off.

Myrinet2000 SAN Card:

When you use Myrinet 2000 cards, please be sure trimmer switch on the cards: speed setting.

Myrinet 2XP

If you want to use Myrinet 2XP, Please keep same toporogy with each Myrinet 2XP port.

If you have 2 Myrinet 2000 switches, please connect one switch to port 0, and connect the other switch to port 1. You don't need connect to both switches.

If you have 1 Myrinet 2000 switch, please select configuration to double number of hosts. And please connect the host to port 0 of Myrinet 2XP. And please connect port 1 from the beginning of the multiple of 8.

For example, if you want to 20 hosts Myrinet 2XP hosts, You select "33 compute hosts to 64 compute hosts". Please cobnect from comp0 to comp19 with port0, And connect from comp24 to comp43 with port1.

Configuration file: 8

2 compute hosts to 8 compute hosts

Using one E16, E32, E64 or E128 with one SW16 card:

Configuration file: SPINE-LINE, LINE-LINE and 16
