vslzConvExec .. ways to make it faster???

[Paul_Margosian]

With considerable help from a Member of this group (Vladimir) have gotten this convolution function to work properly.

In my application, do sets of 2D convolutions (8, 16, etc) and add the results as part of an MRI parallel imaging reconstruction. Currently call vslzConvExec once for each convolution and manage rest of the math externally. It works but, of course, I wish it were faster.

Question: Is there a way to load several sets of data into this function (8, 16, etc) and have the convolutions done all at once? Even if possible don't know whether this would be faster, but it's worth a try.

Hi Paul,

MKL don't provide such functionality.

You couldusenext mode:VSL_CONV_MODE_DIRECT.It may give speed-up forsmall problems.
