Hi
I'm drowning in IPP and MKL documentation
I have been using nsp up till now but now consider changing to IPP or MKL.
It would be very helpful for me if I can get some suggestions on porting.
I'll then would have a starting point.
Myapplication works with lots of large (512*512 up tp 8k*8k) images and fft's,but only one in memory at a time.
I have used the strategy of allocating each row for it self, both image and fft.
That means that I have to build coulmn vectors myself for the vertical FFTwhich slows things down I'll guess.
To use a "Intel" memor allocation would make bigger demand on contimuous free space, wouldnt it?
Up to now, I have used this type ofcall:
nspcrFft( PFloat(floatRArray),
PFloat(floatIArray),
Bits,
NSP_Forw OR NSP_NoBitRev OR NSP_DoFastMMX);
Can someone please comment on the validit of my heap concerns and offer
a suggestion to replacement function (just as a starting point for me)
Also
1: is it to optimistic to hope for a doubled performance on a P4 ?
2: how do I choose between IPP and MKL ?
3: I will extend to 3d soon with objects up to 1k*1k*64, does that have any bearing on the choise above?
