Hello, I'm trying to do my first steps with ISPC.
I understand the concept of ISPC that you write the programs from the point of view of a single element. It is easy to understand in the case there is an array as input and array as output and the ISPC program is the whole program. What I don't get is how it the Box Blur example <https://ispc.github.io/ispc.html#uniform-control-flow> should be used by the host program. let's say we have an image (Single Channel) as mI. Should we iterate it like: for(ii = 0; ii < numRows; ii++){ for(jj = 0; jj < numCols; jj++){ mO[ii, jj] = box3x3(mI, jj, ii); } } But then it doesn't make sense. As it seem a "Gang" will update single value. Could someone show a simple example how to utilize ISPC for Image Filtering?
