How does BLAS get such extreme performance?
...se fixed-size small-dimension operations (called kernels) are hardcoded in CPU-specific assembly code using several CPU features of their target:
SIMD-style instructions
Instruction Level Parallelism
Cache-awareness
Furthermore these kernels can be executed in parallel with respect to each other...

How to calculate a time difference in C++

clock() returns the CPU time consumed by the program. So if the program is run in parallel the time returned by the function would be the accumulated of the time spent on all CPUs, rather than the time elapsed cplusplus.com/reference/ctime/cloc...
CPU指令集avx程序无法运行，运行崩溃 - C/C++ - 清泛网 - 专注C/C++及内核技术
CPU指令集avx程序无法运行，运行崩溃cpu_avx_run原因就是CPU不支持相应的指令集导致的。Linux上使用 lscpu 命令查看CPU指令集，看是否支持。比如_mm256_cmpeq_epi64 这个函数需要avx2指令集，但是CPU不支持，就导致程序崩溃起不来。原因...
Make a program run slowly
... in turn slow everything down. This requires a kernel rebuild.
You can use CPU Frequency Scaling mechanism (requires kernel module) and control (slow down, speed up) the CPU using the cpufreq-set command.
Another possibility is to call sched_yield(), which will yield quantum to other processes, in p...

Android studio using > 100% CPU at all times - no background processes appear to be running
I've noticed Android Studio (when running) uses greater than 100% CPU at all times, even when it appears there are no background processes that the IDE is running (indexing, etc). I might suspect this were something specific to my box, but some fellow developers are encountering this as well.

How does one write code that best utilizes the CPU cache to improve performance?
...
The cache is there to reduce the number of times the CPU would stall waiting for a memory request to be fulfilled (avoiding the memory latency), and as a second effect, possibly to reduce the overall amount of data that needs to be transfered (preserving memory bandwidth).
