Bitonic sort gpu
WebBatcher's odd–even mergesort is a generic construction devised by Ken Batcher for sorting networks of size O(n (log n) 2) and depth O((log n) 2), where n is the number of items to be sorted. Although it is not asymptotically optimal, Knuth concluded in 1998, with respect to the AKS network that "Batcher's method is much better, unless n exceeds the total … WebSep 7, 2016 · 1. Try adding the compile flag "-fopenacc-dim=1024:1:128". GCC 6.1 defaults to using a single gang. This flag sets the default to 1024 gangs, 1 worker, and 128 vectors. – Mat Colgrove. Sep 8, 2016 at 19:38. I get the following message: lto1: warning: using vector_length (32), ignoring 128 I assume the other two values are ok though.
