#4625 — More about scalability...

Hello,


You have seen me doing some scalability projections and
calculations for my parallel Dual Simple system solver,
and i have come to the conclusion that on DDR3 memory systems
you will get  around 4X scalability for larger problems,
but i have forgot to tell you that the future stacked memory
at 1TB/s will allow my parallel Dual Simplex to scale much more than 4X, 
cause the serial part that constitutes the memory transfers of
my parallel algorithm on stacked memory will become more and more 
smaller  compared to the parallel part that constitutes the Divive and 
Multiply and Add asm instructions on two doubles of my parallel 
algorithm , and that will get more and more exciting on stacked memory, 
so i think that i will write my parallel Dual Simplex algorithm.

Read about the stacked memory here:

Thank you,

I mean here parallel Dual Simplex solver, not parallel Dual simple solver.
