Phoronix: A Look At DragonFlyBSD's Kernel Tuning Performance On The AMD Threadripper 2990WX

Last week I posted some initial tests and benchmarks of DragonFlyBSD/FreeBSD on the AMD Threadripper 2990WX. While that went well and the BSDs scale with this 32-core / 64-thread processor better than Windows, lead DragonFly developer Matthew Dillon had picked up a 2990WX system and has been tuning the kernel ever since. Here are some benchmarks looking at some of his recent optimizations...

Hi

Of course, that is an implicit multistage, because it gives the most accurate result due to its iterative scheme. But at the same time, implicit multi-step methods are difficult to implement in practice, because they are quite voluminous.It should be noted here that for solving differential equations both explicit and implicit methods are used, as one step and multi-step. Which one is the best?
