Complex Matrix alignement

Dear Intel developers,

i'm trying to do cache alignement over struct array defined as is:

[cpp]struct complex_32 {
    float32 r;
    float32 i;
};
typedef struct complex_32 complex32;
static complex32  **traces;
traces = (complex32 **)malloc( *num_elems * sizeof(complex32 *));
for (i = 0; i < *num_elems; i++) 
    traces = (complex32 *)malloc( *num_samples * sizeof(complex32));[/cpp]

i want to align for 16 bytes. Which is the right syntax using __declspec(align(16))) ?

Actually, using _mm_malloc instead of malloc, the code crashes on forst _mm_load_ps intrinsic.

Thanks in advance for the help.

Hi unrue,

This forum is dedicated to MPI, Clusters, HPC and so on. Usually engineers who can answer your question visit other forums.

I hope that you got an answer in other thread, so I'll not move it.
