As a former Terp, I could care less! : )
Bombastic Vishkin, way to go!
I got the latest issue of Terp Magazine in the mail the other day (Univ. of MD alumni magazine). Some professor was harping about how distressing it is that since its already been established that global warming (G2K) is man’s fault, he’s so upset that some people still question that.
That was enough for me to tear the thing up and throw it away.
Wow! Now I’ll be able to get my spam email really, really fast...

Thank you for not recycling. No sarcasm intended.
I’d have burned it, makes more CO2.
(humor)
LOL.
I submitted a proposed name: ParTrek.
Is that worth $500?? I definitely think so :)
I took a look at his papers and, best that I can tell, he assumes that calculations can in essense be reduced to tree-searches/operations (e.g., when adding eight numbers, add #1, #2 and #3, #4 and #5, #6 and #7 and #8 (all in parallel) and then add the 1st and 2nd results and the 3rd and 4th results (all in parallel) and then add those two together to get the final number: 7 additions instead of 8 but in, more of less, only about 3/8ths of the time (it gets better with a larger number of numbers to add — assuming a lot of processors).
However, I expect that his method will fail the test of practicality in “The Real World” because of the old problem that *all* parallel processing has - the requirement to rewrite all of that legacy software...
Such rewrites just will not work in the commercial world.
Now, if he could figure out how to build an automatically parallelizing compiler, then he *would* definitely have something :)
Pretty stuff anyhow.
PVC chassis and a radiator fan :)
However, preparing 100 page document for printing isn't much faster today than it was back then.
A perfect example how bloatware wastes resources.
100x faster than today's PC does not mean that the actual work will be much faster.
100 times faster until Mircosoft sends out service pack 1,2,3....9 and you still need Norton......
Just Damn.
I want a galvanized rigid conduit case and fan. Then I’ll be impressed.
With that prop it looks like it could fly....
Preferably, somebody that remembers when memory and cpu cycles weren't cheap.
There are actually parallel libraries out there that work —
But how often does the typical PC user invert a matrix or calculate a heat flow problem (partial differential equation thingus)...
I would argue that typical PC stuff is inherently I/O bound rather than compute bound.
I don’t think fine-grained parallelism will be of much use these days for PCs...
Intel already released a compiler that makes parallelizing code a lot easier, and does some of it by itself. Apple also already has many of its OS Core libraries set up so that a call to one of them automatically runs parallel.
What's new in this?
