"For extreme performance, we discover and use a behavior-out-of-doc PTX instruction: ld.global.nc.L1::no_allocate.L2::256B. This instruction will lead to an undefined behavior: accessing volatile GPU memory with non-coherent read-only PTX modifiers .nc. But the correctness is tested to be guaranteed with .L1::no_allocate on Hopper architectures, and performance will be much better. If you find kernels not working on some other platforms, you may add DISABLE_AGGRESSIVE_PTX_INSTRS=1 to setup.py and disable this, or file an issue."
In the introduction of the paper it says: "Despite its excellent performance, DeepSeek-V3 requires only 2.788M H800 GPU hours
for its full training. In addition, its training process is remarkably stable. Throughout the entire
training process, we did not experience any irrecoverable loss spikes or perform any rollbacks." They have indeed a very strong infra team.
I completely agree with the point you made, as in the choice is much more nuanced, and you do not have to guess my position by the punchline. I never thought of US, in fact I do not know the vaccine policy there. If I was thinking some country while I wrote the comments that would be EU from 2021, when people have to endured some months of inconvenience for not taking any shot. I know some anti-vaxxers even bought virus from other country so that they did not need the vax pass.
Ok I now recall some counterpoints I only heard from my family. In the local community, community workers do visit the seniors to sell off vaccines. So that indeed prove the government did not forget this part. But they certainly not enforce it. To think in other ways, if they should enforced it, maybe it will be even an earlier disaster.
Sinovac is effective to omicron but only with the third booster. In contrast, Pfizer is almost as effective as sinovac with merely two shots in preventing the COVID. So the problem there first is not why they don't import Pfizer, it is why they do not even have sinovac booster.
The answer here is simple: the government do not enforce anybody to get vaccinated. No one. If you missed a corona test at 7am you might be grounded for the rest of week, but if you don't get any vaccine nobody cares. I got two shots of Pfizer not recorded in China, and no one comes to my place like when they want to test you.
Plus there are sporadic side symptoms getting a shot, like arm sore and allergy, some even last to now. Plus plus, for most of people they don't see virus around. So the incentive is zero.
You probably don't have to right to travel freely, but you have the right to not get an injection in China. FWIW.
I could provide maybe another data point there. I lived at a village in a east province for some months and has just left. People are living their normal life, albeit ofc a slightest bit of concern to Corona. But people are more worried that they could not make money now and in near future than having the virus. They are not fearful of starving either, not like people living in the city, farms and fields are everywhere. In the worst time when the town has one or two cases, some are restricted from leaving the county and has to do corona test once for every a while. Some roads are blocked. That is all. But I have heard some worse cases recently, where the cases stays high.
Agricultural population accounts for almost a third of the whole population in China.
To quote an old proverb in Chinese: when there is small turbulance, stay in the city; when there is a big riot, live in your hood.
