Hi everyone, I am testing LoopVectorization in my program and since it did not produce any change in speed, I boiled it down to an exemplary function. Here I found something which puzzled me because although the function is basically a glorified scalar product, which worked well for me in LoopVecto…

Regarding performance of different architectures, here is a table giving the performance of 256-bit gathers using 4 x Int64 indices and loading 4 x Float64. The throughput figures give the reciprocal throughput. Lower is better; you can interpret this as the average number of clock cycles per compl…

Looks like a bug. I would file an issue.
