Generally speaking, if you want to unroll loops and derive a significant performance benefit from it, it is advantageous to move loop-dependent if- statements out of the loop body first. The CUDA compiler knows how to fully and partially unroll loops where it is deemed profitable by heuristics.

WebKARL MAYER’s unwinding creels offer the right solution for every warping job requiring a twist-free operation. These creels are intended for the unwinding of wires, monofilament yarns, tapes and technical yarns which are not allowed to get any additional twist by overhead draw-off. The yarn unwinding tension can be adjusted centrally, and the ... newsinhealth nih
