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."

esd-config

esd-config(1)							   User Commands						     esd-config(1)

NAME

       esd-config - helper script for building with the Enlightened Sound Daemon (esd)

SYNOPSIS

       esd-config [--version] [--prefix=dir] [--cflags] [--libs] [--exec-prefix=dir]

DESCRIPTION

       The  esd-config	tool  enables  you to specify which compiler and linker flags should be used to compile and link programs that use the esd
       library.

OPTIONS

       The following options are supported:

       --cflags        Print the compiler flags that are necessary to compile a program using the specified library.

       --libs	       Print the linker flags that are necessary to link with the specified library.

       --exec-prefix=diIf specified, use dir instead of the installation exec prefix that the library was built with, when  computing  the  output
		       for the --cflags and --libs options. This option must be specified before any --libs or --cflags options.

       --prefix=dir    If specified, use dir instead of the installation prefix that the library was built with, when computing the output for the
		       --cflags and --libs options.  This option must be specified before any --libs or --cflags options. This option is also used
		       for the exec prefix, if the --exec-prefix option is not specified.

       --version       Print the currently installed version of the library on the standard output.

EXAMPLES

       Example 1: Getting the Enlightened Sound Daemon version

       example% esd-config --version

       Example 2: Determining the libraries required to link with the Enlightened Sound Daemon

       example% esd-config --libs

EXIT STATUS

       The following exit values are returned:

       0	Application exited successfully

       >0	Application exited with failure

FILES

       The following files are used by this application:

       /usr/bin/esd-config     Executable for Enlightened Sound Daemon helper script
