The implementation of the SMP system requires collaboration between software and hardware. As a hardware, the CPU that makes up an SMP system must support inter-processor communication, and the hardware must provide a mechanism to maintain the consistency of cache content between CPUs. As a software OS, it is necessary to work with hardware to schedule processes among various CPUs and handle various externa

SMP(symmetrical multi-processing), a symmetric multi-processing system, refers to a group of processors (multi-CPU) that are pooled on a single computer, sharing the memory subsystem between CPUs and the bus structure. It is a kind of parallel technology with relatively asymmetric multi-processing technology and widely used. In this architecture, one computer is no longer composed of a single CPU, while a single copy of the operating system is run by
Reproduced:
Linux has increased support for SMP systems starting with 2.0. In the 2.2 kernel, the SMP implementation at the user level, the Linux kernel itself can not be accelerated because of multiple processors, after the 2.4 kernel, SMP implementation at the core level, the use of multiprocessor can speed up the processing speed of the kernel.

Mutual exclusion under the lock mutex up system under the SMP system
On a single-processor (unique process) system, any number of control paths (multiple threads or multiple processes) that are allowed to occur will have a race condition.
1) Short-term mutual exclusion: in a single processor, if the system is not allowed in the kernel state preemption, then there will be no mutex problem, only allow in the kernel preemption, that is, when the time-sli

1. Summary SMP is called shared memory mulptiprocessors, also known as symmetric multiprocessors ).
The shared storage multi-processor has three models: the uniform-memory-access (UMA) model and the nonuniform-memory-access (NUMA) model) the model differs from the cache-only memory architecture (coma) model, which only uses high-speed cache.
The UMA multi-processor model 8.23 is shown in. As shown in the figure, physical memory is evenly shared by all
In the SMP environment, how does one operate registers on different processors? In the SMP environment, your current code can only run on a certain processor at the same time, so how does this code operate registers on other processors? Let's take a simple example.

The parallelization of matrix multiplication is basically based on the jiagnong algorithm, but with the shared memory, I think jiagnong has no advantage.
Jia Nong ensures a higher degree of parallelism when each variable is a global single copy. When shared memory is used, there is no variable replication cost, so direct use of Band Division can avoid barrier overhead in the middle of iteration and improve efficiency.
