3. Questions related to any architectures. 3.1 Kernel Side. Does Linux support multi-threading? If I start two or more processes, will they be distributed among the available CPUs? Yes. Processes and kernel-threads are distributed among processors. User-space threads are not. What kind of architectures are supported in SMP? From Alan Cox:
https://en.wikipedia.org/wiki/Symmetric_multiprocessing
Symmetric multiprocessing (SMP) involves a multiprocessor computer hardware and software architecture where two or more identical processors are connected to a single, shared main memory, have full access to all input and output devices, and are controlled by a single operating system instance that treats all processors equally, reserving none for special purposes.

In this project, we aimed at implementing Symmetric multiprocessing (SMP) support in Laptop Linux Kernel (version 3.5). That way, we would be functional in revolutionizing the purpose with which children utilize their laptops.

The Linux kernel is a free and open-source, monolithic, Unix-like operating system kernel.The Linux family of operating systems is based on this kernel and deployed on both traditional computer systems such as personal computers and servers, usually in the form of Linux distributions, and on various embedded devices such as routers, wireless access points, PBXes, set-top boxes, FTA receivers ...Developer: Linus Torvalds and thousands of collaborators

Because the Linux kernel supports symmetric multi-processing (SMP) it must use a set of synchronization mechanisms to achieve predictable results, free of race conditions. ... A similar implementation with support for fairness (the CPU cores are allowed in the critical section based on the time of arrival) is used in the Linux kernel (the ...

The following sections describe the changes that have been made to the eCos kernel to support SMP operation. System Startup. The system startup sequence needs to be somewhat different on an SMP system, although this is largely transparent to application code. The main startup takes place on only one CPU, called the primary CPU.

Aug 18, 2008 · Enabling Multiple CPUs (SMP) in Ubuntu Many of today's computers have multiple CPUs. Some are physically distinct, and others are virtual, such as hyper-threading and dual-core. ... all of the default kernels have SMP support enabled. The developers found that there was no significant speed impact from using an SMP kernel on a non-SMP system ...

https://stackoverflow.com/questions/20852902/how-to-check-whether-smp-is-enabled-or-disabled-in-the-kernel
I was wondering how can I check on my running machine, whether the kernel is configured for SMP or not? Of course, I can look into the kernel .config file and can search for it. But, the question is let's say I don't have a source code, how will I check the SMP configuration? Is there any proc file to check it?
