As a software developer using a multi-core processor, you will face the following challenges: Determine whether Threading Technology helps improve performance, whether it is worth your effort, or whether it can be implemented.
Support OpenMP * Intel compiler and thread tools (Intel thread recorder and Intel thread checker) it helps you quickly evaluate the perfor
Enterprise Linux 6 kernel that contains this change from the Red Hat private Bug 765720 is warm booted (for example, via the shutdown -r command):
[sched] x86: Avoid unnecessary overflow in sched_clock
The kernel is warm booted on a machine with any of the Intel? Xeon? E5, Intel? Xeon? E5 v2, or Intel? Xeon? E7 V2 series
CNET Technology Information Network September 8 Beijing report (Text/Liangqing): This afternoon, Intel released three high-performance desktop processors in Beijing: Two Intel Core i7 processors and one Intel Core i5 processor.

process technology or micro-architecture, and continuously improve the processor computing performance, for software optimization and improvement provides an important platform, Enables software companies to provide innovative and optimized solutions for a variety of areas over time. Intel's software and hardware partners recognize that only the hardware is stable and efficient, it is possible to maximize the functionality of the software, and only powerful and reliable
Spectre patch stable version: Intel released micro-code updates for the Skylake, Kaby Lake, and Coffee Lake Processors
Recently, Intel has released stable Spectre patch micro-code updates for Skylake, Kaby Lake, Coffee Lake, and related processors.
The patch, still targeted CVE-2017-5717 Spectre vulnerability. Spectre
Recently saw some notebook upgrade configuration inside the Intel Pentium 2020M this CPU, which makes some people to choose Pentium B960 or 2020M and entanglements. This article will introduce the various differences between Intel Pentium B960 and 2020M processors for your participation.
What are the advantages of Intel
Intel processors implement 4 privilege levels Ring0-ring3
Windows uses two
The implementation of the permission is the range of the value of the address, and the value of several registers
In ring3 work, CS, DS, SS registers are always values 8, 10, and 10 respectively. This allows the system code to monitor the value of the segment registers. Select Sub 1b and 23 for addressing when the kernel (driver,

Comparison of 2.6.1 and Intel assembly language
We know that Linux is a member of the Unix family, and although the history of Linux is not long, many of the things associated with it originate from UNIX. In terms of the 386 assembly language used by Linux, it also originated from UNIX. UNIX was originally developed for PDP-11, and has been ported to the VAX and 68000 series
Compare with Intel assembly language recently in the study of assembly language, the results appear very strange is, under the vc++6.0 code, the GCC compiler code is not the same, later found that Linux inherits the Unix family assembly instructions, usually common is the Intel assembly language. Let's explore the relationship between the two in the next.1. Prefi
