We can probably discuss endlessly, and its fine if we have a different perspective on the topic. But for the sake of discussion, I'd like to reply anyway: it is the area I am working in, and I have thus some vested interest to represent it in a way I deem correct, but also I am interested to see how other people perceive the topic.

I absolutely grant you that the term HPC has a variable definition, in the sense that (a) problems and computers perceived as HPC vary over time, and (b) that it is often used as a marketing label. But that can be said for many aspects in IT: security, Cloud Computing, Grid Computing, P2P, ...

That does not mean that there is not a clear definition, or at least a clear understanding, on what HPC encompasses: in general, it is the area in IT which tries to solve advanced computational intensive problems on clusters or supercomputers.

Now, 'advanced computational problems' - that's a flexible term, and 'clusters' have not been around a couple of years ago, and who knows what the HPC resources will look like in 5 years. But people working in the area have a pretty good understanding of what advanced problems are (no obvious satisfyingly performant solution known on commodity hardware), and of what clusters and supercomputers are.

Best, Andre.

NAME

       term::ansi::code - Helper for control sequences

SYNOPSIS

       package require Tcl  8.4

       package require term::ansi::code  ?0.1?

       ::term::ansi::code::esc str

       ::term::ansi::code::escb str

       ::term::ansi::code::define name escape code

       ::term::ansi::code::const name code

_________________________________________________________________

DESCRIPTION

       This package provides commands enabling the definition of control sequences in an easy manner.

       ::term::ansi::code::esc str
	      This command returns the argument string, prefixed with the ANSI escape character, "33."

       ::term::ansi::code::escb str
	      This command returns the argument string, prefixed with a common ANSI escape sequence, "33[".

       ::term::ansi::code::define name escape code
	      This  command defines a procedure name which returns the control sequence code, beginning with the specified escape sequence, either
	      esc, or escb.

       ::term::ansi::code::const name code
	      This command defines a procedure name which returns the control sequence code.
