[ANN] cpuminer-opt v26.1, Optimized multi-algo CPU miner for x86_64 and AArch64

[JayDDee]

Comparing different algos will only add to the confusion. Figuring out P vs E vs HT is confusing enough.
I suggest you stick with one algo until it makes sense. The radically different results on similar CPUs is
of concern.  Some factors to consider are L2 cache size, and monitoring the CPU cores to confirm thread
distribution is as intended.

So if yespower is memory bond than cpu speed, how i can configure the memory in Linux to work best for cpuminer-opt v25.1? Is hugepages setting has any effects for cpuminer-opt? Or that it just need ram with recent speed or l1,l2,l3 of processor size?

There's no real short answer for this, pretty much all of the above. You can enable transparent huge pages on Linux and give it a try.
If hugetlbfs is enabled verthash and scryptn2 will try to use them.

Edit: a little clarification: I/O bound doesn't mean it uses a large amount of memory, it means it accesses memory a lot. Huge pages won't help with that.

enable huge pages is possible on windows too, just a few steps in regedit!

Is there any CUDA/GPGPU miner for SHA-256 hashing?

Preferably a recent one with optimizations for modern nVidia GPUs with big L2 caches.

Although it is of course impractical to mine on GPUs, you may refer to ccminer, which implements several algos in CUDA:

There is no recent GPU miners with SHA-256 support. It doesn't make sense.
