If you loose vectorization, you might be loosing a 4x, 8x, 16, ... 32x perf difference by organizing your data in such a way that memory operations and data manipulation can't be vectorized.

This is how I think about it as well. Which makes me wonder if Mach wasn't right all along.

This seems to have been downvoted. If someone knows of any performance analysis of wlroots, with a per frame analysis of perf, please go ahead and share it.

If your problem is "speeding up X", one of, if not the first question you should ask is: "how fast can X be"? If you don't know, find out, because maybe X is already as fast as it can be, and there is nothing to spe

Sure, its more complex than that, and an accurate model would be more complex as well. But hey, doing science[0] is hard, better not be scientific instead /s [1] science as in the scientific method: model->hypothesis->test , impr

Are they the small disaster ? What do you think is going to happen with all the lithium after being bounded by a 10 year old with a rock? Probably just going to land in the river, and then the sea.

Your network links supports certain throughput and latencies depending on the packet sizes. Your vendor should tell you what these are, and provide you with benchmarks to reproduce their claims (OSU reproduces these for, e.g., MPI). The net

Nobody here is talking about vectors of integers. From the first post, this is all assuming that the objects in the vector are "big". A modern CPU has 200Gb/s of bandwidth. If the objects in your array are 200 Gb in size each
