1 > The mere fact you are asking/questioning with the term….

3 Well… sorry, I'm not asking :) As you probably can see, I'm trying to
4 give some input of basic Scal@Grid assumptions and to hear some
5 opinion back from people who believes they're men on this.

7 I agree with your statements/terms above and RT as a science on the
8 end – there is no magic or questions around - too much info is
9 available from lots of universities, papers, researches, etc.
10 And of course there is no question for FT and HA, techniques,
11 approaches, methodologies, but...
12 But let me please to continue in a different way. We will remove a
13 science, a fault tolerance, HA and other thing that can confuse you,
14 James (in advance – please be sure - I'm really happy that I found you
15 and you can express your opinion on the subject)

18 So, we're considering some system that (we think so here) can
19 guarantee (by some way that is not important at this step) meeting its
20 deadlines with a given (by the operator) probability. It uses some
21 techniques that adapts to the given (read - required) probability and
22 actually proves that it achieves the requirement with the probability.
23 Does it mean a system is a HRT? why/thoughts (?)
24
25 We imply here that true HRT is impossible in reality and any single
26 system that exists in the word meets hard real-time requirements with
27 some probability. If it does not – HRT speaks of system failure.
28
29 Please note, we speak of free programmable generic system here,
30 something like a programmable logic microcontroller for custom
31 application development. Any systems like DSP/matrix/etc are out of
32 scope.
