Things have changed, but mainly (perahaps all), it is a difference in
licensing.
Previously (i.e.version 6 or earlier), if you want to use parallel
computing, you had to either.
1) Buy Mathematica plus the parallel computing toolkit (PCT), plus I
assume some licenses (perhaps the PCT comes with one). The PCT is a
mathematica package, which adds some new functions for parallel
computing.
2) Buy Mathematica Personal Grid, which allows up to 4 CPUs. I do not
believe you can extend it beyond 4 CPUs - a license rather than a
technical limit.
3) Buy gridMathematica, which comes with licenses for up to 8 CPUs,
which can be on different machines. You can also purchases licenses
for as many CPUs as your budget permits.
The difference is now that with Mathematica 7.0, up to 4 CPUs can be
used with no extra charge. I assume this effectively means that
'Mathematica Personal Grid' is a defunct product. Likewise I assume is
the parallel computing toolkit.
That at least is my understanding of it.
