I want to keep my code from flushing off the L2 cache as much as possible. How would you achieve that in C++ / C# and how would you make it accountable. EDIT : can I collect number of L2 cache misses alternatively? Answer : Yes Can I get the L2 cache miss count of each process on the windows platform?

Jul 30, 2010 · As stated in this thread, simply using the CPU can cause the contents of cache to change. Since (most) cache implementations are intentionally completely transparent to the CPU, you will not be able to view the contents of the cache directly from within software running on traditional CPUs.

Cache Hierarchy So far, only one layer of cache has been discussed. If cache is fast but small and DRAM is large but slow, why not just add more layers of cache that get progressively larger, but slower? That is exactly what modern CPUs do.

I understand that the processor brings data into the cache via cache lines, which - for instance, on my Atom processor - brings in about 64 bytes at a time, whatever the size of the actual data being

Aug 16, 2018 · It's best to leave cache at stock. Overclocking cache doesn't really do too much for performance and it can destabilise your overclock. AFAIK, overclocking cache helps with L1/2/3 cache bandwidth and latency.

Jun 12, 2021 · On the cpu cache issue, try making a large 2d array of equal width and height. Write a for loop within a for loop to increment every value in the array and time how long it takes.

Feb 4, 2014 · What is a speed of cache accessing for modern CPUs? How many bytes can be read or written from memory every processor clock tick by Intel P4, Core2, Corei7, AMD? Please, answer with both theoretic...

Jan 28, 2011 · The answer to this question strongly depends upon the architecture and the cache level, along with where the threads are actually running. For example, recent Intel multi core CPUs have a L1 caches that are per-core, and an L2 cache that is shared among cores that are in the same CPU package; however different CPU packages will have their own L2 caches. Even …

Jun 24, 2021 · Modern CPUs ( I'll use the 5950x for example) only have around 64mb of L3 cache. Why can't we just put gigabytes worth? I always wondered why they don't just build larger CPUs to fit the cache. Or maybe with the shrinking of components, they could fit larger amounts in the same size chip.

Sep 26, 2014 · The CPU and the RAM are separate objects, though, so it takes time, albeit a very small amount of time, to transfer something from RAM to the CPU so that it can actually do stuff with that data. The cache is a much smaller memory storage that's actually on the CPU, so it can be accessed much faster.
