How to determine whether a given Linux is 32 bit or 64 bit?
... ==> 32-bit kernel
Otherwise, not for the Linux kernel, but for the CPU, you type:
cat /proc/cpuinfo
or:
grep flags /proc/cpuinfo
Under "flags" parameter, you will see various values: see "What do the flags in /proc/cpuinfo mean?"
Among them, one is named lm: Long Mode (x86-64: amd64, a...
Why is Node.js single threaded? [closed]
...In my opinion that theory's been borne out. A node.js app that isn't doing CPU intensive stuff can run thousands more concurrent connections than Apache or IIS or other thread-based servers.
The single threaded, async nature does make things complicated. But do you honestly think it's more complica...
Is volatile expensive?
...n the page I see that LoadLoad and LoadStore are effectively no-ops on X86 CPUs. Does this mean that volatile read operations can be done without a explicit cache invalidation on x86, and is as fast as a normal variable read (disregarding the reordering constraints of volatile)?

Multiprocessing vs Threading Python [duplicate]
...m though if there are too many processes being spawned too often since the CPU might run out of processes/memory. But it can be the same in case of too many threads spawned too often but still lesser overhead than multiple processes. Right?

What are the differences between the threading and multiprocessing modules?
...cores, and change your code to use 8 threads, it won't be able to use 800% CPU and run 8x faster; it'll use the same 100% CPU and run at the same speed. (In reality, it'll run a little slower, because there's extra overhead from threading, even if you don't have any shared data, but ignore that for ...
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 do I fix the Visual Studio compile error, “mismatch between processor architecture”?
...rying to warn you when you state that your project is compatible with "Any CPU" but you have a dependency on a project or .dll assembly that is either x86 or x64. Because you have an x86 dependency, technically your project is therefore not "Any CPU" compatible. To make the warning go away, you shou...
