which approach to these kinds of problems be more efficient? Is it mapping or using something like ISPC

@marwan I would think that ISPC is more efficient in terms of utilization, but doesn’t apply to as many problems. For example, I would think using ISPC to interact with objects would be complicated, is it may no longer be as simple as loading a vector of adjacent elements, but maybe having to stride memory accesses, or load at unrelated locations in memory of following a pointer, etc
