Good post.
On these topics, I find the definition of the term is relative to where the person "sits".
For example, HPC to a web architect is very different than HPC to an ASIC designer and is also very different to a trading systems architect. That is why I said the use of the term is relative.
The same is true for other TLA, like SOA, for example. To a CIO, a "service" might be defined as a massive globa IT system. To the web architect, a "service" might be a payment gateway. To a programmer, a "service" might be a piece of code in an object oriented design library. To a chip designer, a "service" might be a graphics card on the motherboard bus.
"High Performance" is relative to the application, which is very different depending on where you "sit". This is also very true for the term "computing".
These terms are relative to the level of architectural and application abstraction and granularity.
This concept is hard for many people to grasp, especially those who work in a specific area and who define terms based on their own perspective; and often this is a major cause of problems in IT systems design because people tend to forget that the perspective of the user defines their worldview.
Another way of saying this is "All politics are local."

net::dbus::service
Net::DBus::Service(3pm) User Contributed Perl Documentation Net::DBus::Service(3pm)
NAME
Net::DBus::Service - Provide a service to the bus for clients to use
SYNOPSIS
package main;
use Net::DBus;
# Attach to the bus
my $bus = Net::DBus->find;
# Acquire a service 'org.demo.Hello'
my $service = $bus->export_service("org.demo.Hello");
# Export our object within the service
my $object = Demo::HelloWorld->new($service);
....rest of program...
DESCRIPTION
This module represents a service which is exported to the message bus. Once a service has been exported, it is possible to create and
export objects to the bus.
METHODS
my $service = Net::DBus::Service->new($bus, $name);
Create a new service, attaching to the bus provided in the $bus parameter, which should be an instance of the Net::DBus object. The
$name parameter is the qualified service name. It is not usually neccessary to use this constructor, since services can be created via
the "export_service" method on the Net::DBus object.
my $bus = $service->get_bus;
Retrieves the Net::DBus object to which this service is attached.
my $name = $service->get_service_name
Retrieves the qualified name by which this service is known on the bus.
