That isn't really a failure case in cuda (or opencl). It's very common to launch more blocks/workgroups than can be resident simultaneously on the GPU.

Is it just the normal difference between e.g. an engineer's approach to real analysis and a mathematicians (but complex analysis swapped in), or something else? I can think of a lot of fields where a decent grasp of complex analysis co

For reference (because I didn't know the comparison): MI60 has 7.4 TFLOPs double precision at TDP=300W.

access violations are generated internally by a single instruction, and all mainstream CPUs guarantee precise exceptions. PMU interrupts for sampling are external so the CPU picks wherever it wants to stop in the program.

I didn't say you could materially reduce fires, only the ones caused by PG&Es negligence. There will still be fires, but maybe they won't be caused-in-fact by lack of reasonable maintenance of power lines.

If you are trying to reduce the risk of wildfires caused by PG&Es negligence, increasing its legal liability is the best place to push.

He did always strike me as more of a bullshitter profiting off of ML hype than anything else, so this actually makes a lot of sense.

OP, I'd be interested if you could highlight what interested you about CDs.

This would make a lot more sense if the failures of PG&E infrastructure that caused previous fires were not because of negligence. It's one thing to criticize the utility for a rare failure when they engaged in reasonable maintenan

Lempel-Ziv isn't a language, it's a class of compression algorithms. And personally I have a hard time directly consuming compressed text.

No, that page is about kernel performance, not sanitizer performance. The idea is that if you omit READ_ONCE/WRITE_ONCE when they are needed, it doesn't matter if the code is faster because it is wrong.
