A detailed description of how Python handles concurrency using the Asyncio package

This article mainly for you in detail the Python use Asyncio packet processing concurrency related data, with a certain reference value, interested in small partners can refer to Blocking I/O and Gil The CPython interpreter itself is not thread-safe, so there is a global interpreter lock (GIL) that allows only one thread to execute Python bytecode at a time. Therefore, a Python process typically cannot use multiple CPU cores at the same time. However, all functions in the standard library that

address space and physical address correspond to the virtual address space and virtual address. In most cases, the physical address space of our system is only a subset of the virtual address space, here is a simple example to illustrate the two. For a 32-bit x86 host with a memory of MB, its virtual address space ranges from 0 ~ 0 xffffffff (4G), and the physical address range is 0x000000000 ~ 0x0 fffffff (256 MB ).On a machine that does not use virtual memory, the virtual address is directly

Those things on Tianhe 2 (1)

I believe everyone knows about Tianhe 2, ranking first among the top 2013 and 2014 top500, which is one time faster than the top 2nd Titan, what kind of architecture does Tianhe 2 use to achieve this capability? Let's take a look at it. Tianhe No. 2 Model for TH-IVB-FEP, using the central processor and co-processor computing architecture layout: Tianhe 2 has a total of 16,000 computing nodes, each of which is equipped with two Xeon E5 12 core central processors and three Xeon Phi 57 core coproc

The "non-preemptible multitasking" slows down when there are more programs, because it allocates a lot of time to programs that are useless to users.

enhances this SIMD capability and introduces the SSE (streaming SIMD extensions) extension. This feature enhances the functionality of 8 128-bit registers (XMM registers). These registers do not overlap with FPU/MMX registers, so they can be mixed with FPU/MMX instructions. Pentium IV also introduced sse2 extensions that support high-precision floating point values. sse2 and SSE use the same XMM register group. The 80x86 microprocessor does not store FPU, MMX, and XMM register values in TSS, bu
