The P2P case this article discusses is "peer-to-peer lockstep", which is only a small subset of possible p2p systems. (it's called peer-to-peer instead of client-to-client, because there is no client role in such a system).

Somehow networked shooters manage to leverage it. They probably only use unreliable messages for the twich mechanic hot-path which is heavily analyzed, iterated and tested anyway.

If you don't trust it, it can do it any way it wants to - including spoofing traffic from the host or modulating timing of unaltered packets from the host.

Nitpicking: in the offline rendering world RenderMan had shaders ca. 1990[1], and graphics hackers got around to compiling those for research GPUs in the 90s too[2]. (Hardware had programmability equivalent to current shaders early as well

I find it's conductive to rewriting that I can iterate with only one or two codepaths of the remodeled core working before settling on something and fixing the rest of the codebase to match. (nit: dynamically typed != no types)

No functional need for a separate VM: xvfb-run -a will automatically pick the next free display number and set up the environment pointing to xvfb's $DISPLAY. Of course container/vm isolation is still a good idea for security and

Very US-centric view. In many places daycare is heavily subsidized and it makes financial sense to stay at work with 2-3 kids.

Your needles (search terms) need to be quite long if you want to save on memory traffic: cache lines are 64-128 bytes and random access to standard DRAM is slower than sequential access. It can help if your data is in-cache though. (Or if y

Depending on your language, you may not need explicit language support. For example these guys have a runtime codegen library that they use (on Scala): https://ppl.stanford.edu/papers/popl13_rompf.pdf There's also

Last I heard it was a fragile benchmark stunt, and compilers would enable the optimization in only very limited circumstances. Has there been progress since?

Good point, it's depressingly common. It's not hard to DTRT though. Eg Docker install instructions have 4. Add the new GPG key. $ sudo apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys 58118

If you look at the bug filed against the man page, it doesn't exactly make a strong case. It just suggests some weasel words, about qualifying "large amount of data" etc. ( https://bugzilla.kernel.org/show_bug.

Vegetarian diet isn't really connected to low-fat. Meat generally decreases your food's average fat content, since most meat is lean. Vegetarians make up lack of lean meat with more fatty dairy and cholesterol raising eggs.

SPMD is conceptually more like a job system, so this generates code that is not necessarily all executing same code in lockstep. SPMD/SIMD is "single program" vs "single instruction". The compiler does also exploit
