Is this the right Scenario for TBB ?

Hello,

I have to the develop the following project:

My data is divided into 12 **2D **complex float matrices.

Each complex matrix is then separated into 2 float matrices: Real and imaginary.

The reason for this: The signal processing contains also transpose.

There is no IPP transpose for complex float.

So I have 24 float matrices. Each row is consecutive in RAM.

On each marix I have to run FFT on each row, multiply each row by a constant vector (sample by sample) and then FFT on columns.

Before FFT on columns I will have to transpose because FFT on columns will be slower due to cache.

Now to my question:

Is it right to use TBB on each matrix in order to use all cores ?

I have 24 matrices but only 4 cores in my CPU.

Thank you,

Zvika
