Now, for the real kicker. The 5800X3D has a 96MB L3 cache (32+64) as compared to the 32MB cache found on the standard 5800X. That’s a whole 64MB more, putting it above even the Ryzen 9 5950X in terms of cache.

The general conception of a tipping point is that there’s some fixed physical threshold beyond which the system trips into a different state. But they found that a lesser-known phenomenon known as a rate-­induced tipping point, triggered by a sudden increase in the system’s rate of change, might halt the currents as well. In other words, too much change occurring too fast could cause the system to break down. The Atlantic circulation could be susceptible to this if the water flowing from ice sheets increases rapidly enough, according to the study, which was published in the Proceedings of the National Academy of Sciences in March.

It’s just one model and one study, but it suggests that the climate system could be more fragile than previously appreciated. These “chaotic dynamics” mean that “we maybe cannot expect, even if our models get much better, to be able to predict with 100% confidence whether such an element of the climate system will go into another state or not,” Lohmann says.

Sadly, it has been suggested several times to the project that they reduce the length of deadlines. I am not sure what the reluctance is about.

... with adding a second getting close to doubling throughput but the third and fourth tasks only gave marginal gains.

Some have been as low as 4GB/task in the past so this small testing batch of three tasks is no guarantee that they will be as heavy on RAM when they finally make it to the main site or it may be like the testing ones, some are as bad and others are lower. But I am ordering some more RAM as with 8 real cores, it is pretty clear 32GB does not cut the mustard any more.

Peak usage for latest OpenIFS tasks in testing is about 12GB!

It's amazing how much math my generation can do in our heads compared to kids today that need a calculator to do the most rudimentry arithmetic.

Any thoughts about my questions on CPU cache limits and using sec/TS?

China broke the record by keeping the Experimental Advanced Superconducting Tokamak (EAST) by achieving plasma temperature at 120 million Celsius for 101 seconds and 160 million Celsius for 20 seconds, a major step toward the test run of the fusion reactor.

And now a paper is suggesting the AMOC might stop working.

I don't think there has been a lot new in the science of fusion. It has been an engineering problem for a long time now.
