Dear colleagues, 

I apologize for repeating myself.

Perhaps you could comment on
 James Demmel's recent posting in which he
refers to a nice result for the related objective of summation of
n numbers, accurately. This method can use one
or more processors such as are currently available, uses a
small number of registers, and is modestly slower than
 the obvious method for (unreliable) summation.


While your proposals are interesting, to achieve the claimed
speed would require special hardware (hardware which
is not commercially available).   So we must consider if
the EDP is worthwhile to incorporate in the 1788 standard
if it were inevitably implemented in software.  Which means
it should be compared to other software schemes such
as Demmel's  (and MPIR -- which of course does far more
than EDP).
