Hi, I'm looking for a fairly recent blog post. The author was looking at how to reduce (sum, or maybe count occurrences) an array quickly. I think this was specifically on a single core of a modern Intel CPU - i.e. looking at microarchitectural influences, rather than throwing relatively coarse parallelism at the problem. I do remember a specific trick used was to keep multiple copies of the reduction variable, because even on a single thread it allowed the scheduler to make better use of ILP in an unrolled loop (or similar). Does anyone have a link to the post I'm thinking of? Thanks. 82.13.241.56 (talk) 03:26, 7 February 2015 (UTC)
Does Qatar have "normal" IP addresses yet? MediaWiki:Blockiptext still mentions only Special:Contributions/82.148.96.68 and Special:Contributions/82.148.96.69, but both of them have been inactive for several years now. Nyttend (talk) 14:29, 7 February 2015 (UTC)
