Call multiple CUDA SVD (in cuSolver)

I would use the SVD routine of CUDA 7.0 (cuSolver), i need to perform the SVD on all parts where i split the matrix (for example, dividing the matrix into 2x2 blocks, I want to perform four times the SVD in parallel) . The idea would be to invoke several times the kernel in relation to the matrix subdivision. so:

for loop(istart){
   for loop(jstart){
       "invoke kernel"
   }
}

But in this way the call to the kernel is serial, not parallel. Since there isn't the possibility to invoke these functions from the kernel, how can I parallelise these calls?

Are you talking about cuSOLVER? How does your matrix structure look, for which parts do you need to perform SVD etc.? Be more specific. – m.s. Apr 01 '15 at 08:33
Yes m.s. sorry, i edit! – sim186 Apr 01 '15 at 08:34

Unfortunately not. This example run on the whole matrix. I need to invoke this routine on all parts of the matrix. – sim186 Apr 01 '15 at 08:55

The answer mentions the creation of streams for this exact problem, did you try this? – m.s. Apr 01 '15 at 09:05
