I tried to compile the fftw project with Parallel Composer but get error... it will have a 64bit project, but this is win32.
Looks like I must additional install the Composer for 32bit..
Please have a look at the resultfiles from the fibonacci project, it is 64 bit compiled with Composer

Hi Heinz, Why did it choose 5 threads instead of 8 ?
--- Quote ---Threads number is 5
--- End quote ---
test before that is 4, next is 16, so it seems a bit weird. I have some fibonnaci example project I did here with TBB a while ago. Will see if I can dig it out.

5:8 should be 5(1) to 8, hmmm 1:4 did work as you can see
echo off
echo please wait
echo fibonacci result in fibonacciopt_1000_out.txt
rem no second parameter means standard(1:4)
fibonacci.exe 1000 >fibonacciopt_1000_out.txt
echo fibonacci 1000 5:8
fibonacci.exe 1000 5:8 >>fibonacciopt_1000_out.txt
echo fibonacci 1000 16
fibonacci.exe 1000 16 >>fibonacciopt_1000_out.txt
echo fibonacci 1000 32
fibonacci.exe 1000 32 >>fibonacciopt_1000_out.txt
echo fibonacci 1000 64
fibonacci.exe 1000 64 >>fibonacciopt_1000_out.txt
echo ready
you can compare with the other result file to see differences

Downloading Parallel Composer beta now, for cooperative exploration & development. If we can do something with FFT & FFA that would be good IMO for astropulse, but there are strong possibilities for Multibeam softawre as well (maybe more, because it has a higher degree of serial optimisation already)... Will See.... This Beta software better not mess up my ICC/IPP installation! :o
