HyperFabric Configuration Guidelines

Hyper Messaging Protocol (HMP)

HP-MPI is a native implementation of version 1.2 of the

Message-Passing Interface Standard. It has become the industry

standard for distributed technical applications and is supported on

most technical computing platforms.

HMP is certified with HP-MPI 1.7 on both HP-UX 11.0, 11i

v1 and

11i v2.

HMP is also certified with HP-MPI 1.7.2 which uses HMP as the

default interconnect.There are distinct differences between the

feature set that is supported for HMP and the feature set that is

supported for TCP/UDP/IP.

Features

The following are the HyperFabric features on HMP:

• OnLine Addition and Replacement (OLAR): Not Supported

The OLAR feature, which allows the replacement or addition of

HyperFabric adapter cards while the system (node) is running, is not

supported when applications use HMP to communicate.

• Event Monitoring Service (EMS): Supported

Starting with the December 2000 releases of HyperFabric

(B.11.00.11 and B.11.11.01), the HyperFabric EMS monitor allows

the system administrator to separately monitor each HyperFabric

adapter on every node in the fabric, in addition to monitoring the

entire HyperFabric subsystem. The monitor can inform the user if

the resource being monitored is UP or DOWN. The administrator

defines the condition to trigger a notification (usually a change in

interface status). Notification can be accomplished with a Simple

Network Management Protocol (SNMP) trap or by logging into a

user specified log file with a choice of severity, or by email to a user

defined email address.

implementing this feature, see the HyperFabric Administrator’s
