speedup for non square matrix multiplication

[ssara]

hi everyone

am using multicore toolkit for matrix multiplication 4x4 with 4xV where V vary from 100 to 10000000

why the speedup decrease for larger value of V ?

I'd wager the computer gets occupied with memory management instead of calculating.

You did not attach your subVI.

Your "computation time" graph would look better with logarithmic Y mapping.

Why do you again create such a worm of a sequence structure (compare to our old discussion!).

i just work in this vi to display various size together, regardless the worm structure also in the (old vi) the speedup decreased for large # of points!

are there any error in the vi??
