Hi David, or whomever
We have found that to make best use of vector operations in the Xeon Phi
machines that we have to de-interleave the complex data. That is a
single long array of length 2N
[re1, im1, re2, im2, ....,reN, imN]
gets de-interleaved into two arrays
[re1, re2, ....,reN]
[im1, im2,..., imN]
before the data are loaded into the vector registers. Is this done in
XGPU, or is it not necessary?
If de-interleaving is done, then where is it done? In the GPU? Or in
memory prior to GPU?
Thanks
Gerry
